A general flavonoid pathway is used by plants for their synthesis. Chalcone isomerases convert naringenin chalcone to naringenin [ 54 ]. Naringenin then undergoes several hydroxylation steps to form anthocyanins. A schematic representation of the anthocyanin formation pathway is provided in Figure 3. Biosynthesis of anthocyanins in plants. Traditionally anthocyanins from plants have been used for treatment of hepatobiliary issues such as hyperbilirubinemia, obstructed bile ducts and treatment of lack of appetite [ 55 ]. In this section several therapeutic uses of anthocyanins reported in literature are discussed. A list of the effect of anthocyanin treatment in disease conditions and the tested pathological markers is provided in Table 2. Effect of anthocyanin treatment in disease conditions and the tested pathological markers. Anthocyanins act as good free radical scavengers due to the keto group with a conjugated double bond. The high reactivity and instability of aglycones in their structure provides an advantage for anthocyanins in acting as antioxidant agents [ 61 ]. Glycosylation reactions reduce and diacylation reactions increase their free radical scavenging activity. Anthocyanins have been investigated in various systems and models for their antioxidant effect. In a study investigating the formation of malondialdehyde after UVB irradiation, delphinidinglucoside and pelargonidinglucoside exhibited significant antioxidant effects [ 62 ]. Pelargonidin acts as an excellent hydroxyl radical scavenger, and delphinidin acts as a good oxygen radical scavenger. Studies also report cyanidin and cyanidinglucoside to possess inhibitory effects against oxidation of low-density lipoproteins LDL [ 63 ]. Angiogenesis is the process of development of new blood vessels with the help of endothelial cells. Chemical mediators within the body angiogenic and antiangiogenic factors maintain the environment required for normal angiogenesis. Angiogenic factors include growth factors such as vascular endothelial growth factor VEGF , angiopoietin and fibroblast growth factor. Antiangiogenic factors include factors such as thrombospondins. Disruption in the balance between these factors can lead to complications in disorders such as diabetes and cancer. Reports published on evaluation of expression of VEGF reveal that colored berries due to their anthocyanin contents, reduce expression of VEGF and VEGF induced tube formation in ex-vivo models of human cell lines, under oxidative stress [ 64 ]. When high glucose concentrations were induced in human endothelial cells, anthocyanins from purple corn were found to inhibit expression of angiogenic factors [ 65 ]. Angiogenesis play a very critical role in proliferation of cancer cells. Reports suggest that anthocyanins extracted from berries have antiangiogenic effects in various cancer cell lines. Blue berry, bilberry and black rice anthocyanins are reported to exhibit anti-invasive properties in breast cancer cells and in in-vivo animal models by reducing the expression of cyclooxygenase-2 gene [ 65 ]. Other mechanisms of action reported for anticancer effect of black rice include suppression of activation of mitogen-activated protein kinase MEK , and decreased expression of matrix metalloproteinase 2 MMP2 and matrix metalloproteinase 9 MMP9 [ 66 ]. A study of purple potato anthocyanins in CF-1 mice model reports the antitumor effect of its extracts in colon cancer by induction of cell-cycle arrest [ 66 ]. Anthocyanins from Cornus fruits are reported to induce insulin secretion in ex-vivo rodent beta cells. Cornus fruits are used in Traditional Chinese Medicine as antidiabetic agents. It is reported that the property of inducing insulin secretion in anthocyanins may be due to the hydroxyl groups in their B-ring [ 67 ]. Anthocyanins reported to induce insulin secretion include delphinidinglucoside and pelargonidingalactoside. Seoritae extract is reported to inhibit diabetic nephropathy by suppressing renal lipid deposition [ 68 ]. Anthocyanins from Bilberries act as antihyperglycemic agents by stimulating the adenosine monophosphate-activated protein kinase AMPK. Bilberry extracts are also reported to improve visual function in patients suffering from diabetic neuropathy and glaucoma [ 69 ]. Neuroprotection is achieved by reduction in toxic effects and injuries caused to neurons due to oxidative reactions. Cyanidin glucosides are reported to inhibit DNA fragmentation and oxidative stress caused due to hydrogen peroxide formed in-vivo in human neuronal cells [ 70 ]. Tart cherry anthocyanins, when tested for neuroprotective activity in mice brain under oxidative stress inhibited generation of apoptosis-inducing factor [ 71 ]. CyanidinO-β- d -glucopyranoside and petunidinglucoside isolated from mulberry and black soybeans, are reported to exhibit neuroprotective activity in ex-vivo models. They inhibit cerebral ischemia and cell death caused due to hydrogen peroxide induced oxidative stress [ 72 , 73 ]. Incorporation of anthocyanins as an ingredient in foods and pharmaceutical has undergone several challenges. The prime issue with their use, is their stability and hence their effectiveness as a beneficial component in food and pharmaceutical. Anthocyanins are used as colorants in pharmaceuticals and food products as a substitute to synthetic colors. Studies have compared the stability of anthocyanins as colors with synthetic colors and have found that the synthetic colors have better stability than anthocyanins. In a study, stability of synthetic colors such as Carmoisine, Allura red and Ponceau were compared with natural anthocyanin colors, viz. enocyanin, dark carrot and cochineal. The results of the study indicate that at higher temperatures and higher pH conditions the stability of natural anthocyanins was much lower that the synthetic colors [ 74 ]. However, the beneficial effects of anthocyanins cannot be ignored due to their stability issue. In another study, the stability of freeze-dried powder of anthocyanin extract of wild blueberry was compared at various temperature values over a storage period of more than a month. It was observed that the total anthocyanin content and the content of individual anthocyanins was most retained at 25°C and reduced significantly at higher temperatures [ 75 ]. A combination of ascorbic acid with anthocyanins from plant extracts was evaluated for stability under varying humidity, temperature and pH conditions in both freeze dried and solution form. It was observed that in solution form the stability of the combination reduced with increase in pH and temperature. In freeze dried form the stability of the combination decreased with increase in humidity [ 76 ]. Commercially several yoghurt variants are available with a variety of fruits. Some studies carried out on extracts of blackcurrant and wine grape extracts in yoghurt indicate that the fermentation process and addition of some probiotics reduce the stability of anthocyanins [ 77 , 78 , 79 ]. Microencapsulation is another technique tested for anthocyanin release and stability. In a cell line study carried out microencapsulated glycons and aglycons of some anthocyanins, glycons of anthocyanins were found to be more stable than the aglycon counterparts [ 80 ]. The conventional extraction methods are cost intensive and employ application of heat for extraction. Ground breaking research has been carried out in metabolic engineering of microbes for production of anthocyanins. Cyanidin 3-O-glucoside has been successfully produced by E. However, its production at commercial scale poses challenges due to imbalances in the expression of other genes and lack of optimized transporters for extracellular secretion [ 81 ]. The merger of metabolic engineering with plant chemistry holds a promising future for anthocyanins and their application in food and drug industry. The evidences provided through scientific studies till date, demonstrate the therapeutic benefits of anthocyanins. The anthocyanins are excellent natural sources of bioactive compounds that can help in treatment and prevention of many disease conditions. With the multidisciplinary research carried out in the last few years, anthocyanins have a promising future for their commercialization and application in the pharmaceutical and health foods sector.

Despite this belief, there are still no reports of severe side effects caused by anthocyanins. To avoid all side effects, choose to obtain anthocyanins through food. If you do take supplements containing anthocyanins, use them only as directed, and never take more than you should. Some people may need to take extra precautions when using anthocyanins in supplement form. Anthocyanins are thought to be safe when consumed through food. However, the safety of anthocyanin supplements in certain populations has not been established at this time. Children, people who are pregnant or breastfeeding , and those with medical conditions should seek advice from their healthcare provider before using anthocyanin supplements. Always speak with a healthcare provider before taking a supplement to ensure that the supplement and dosage are appropriate for your individual needs. When it comes to anthocyanin supplements, there are no guidelines for recommended dosage. More research is needed to establish safe dosage information for all people. There is also no Dietary Reference Intake DRI for anthocyanins from food. However, a joint committee comprising the Food and Agriculture Organization of the United Nations FAO and the World Health Organization WHO has established 2. However, this recommendation applies to anthocyanins from grape skin extracts, not anthocyanins in general. The committee found this to be a safe, nontoxic dose. If necessary, your healthcare provider can help determine the right anthocyanin dose for you. You may be more likely to experience side effects if you take a dose of anthocyanins that is too high. However, anthocyanins are generally considered safe, especially when consumed through food. Reports of anthocyanin toxicity or overdose have not been made. Anthocyanins have also been labeled as having low to no toxicity. Regardless, it's still important to be safe and only use anthocyanin supplements as directed. You should also only consume anthocyanins through food in normal amounts. Anthocyanins may interact with certain nutrients and medications. Some research suggests that anthocyanins interfere with various enzymes and protein transporters responsible for helping the body absorb some nutrients, like thiamine and folic acid. Anthocyanins may also affect enzymes or transporters needed to metabolize certain medications. Unfortunately, anthocyanin interactions are not well-documented or understood. It is also important that you carefully read the ingredients list and nutrition facts panel of a supplement. This will ensure you know which ingredients are in the product and how much of each ingredient is included in the supplement. For best practice, please speak with your healthcare provider regarding the potential for interactions between anthocyanins and any other supplements or medications you take. Anthocyanin supplements should be stored in a cool, dry place. Keep them out of direct sunlight. Foods containing anthocyanins should be stored normally. To ensure proper shelf life, always keep supplements in their original bottle or packaging. You should also keep anthocyanins out of the reach of pets and children to prevent accidental ingestion. Discard all supplements once they reach their expiration date. Various supplements have been researched for similar uses to anthocyanins. These include:. Talk with your healthcare provider about which supplement is best for you. Anthocyanins contain antioxidant properties, which means they can act like antioxidants. In fact, many of the reported health benefits of anthocyanins are thought to be due to antioxidant activity. Antioxidants scavenge for potentially harmful free radicals in the body. Anthocyanins are a type of water-soluble flavonoid. Flavonoids are a type of phytochemical, which are compounds found in many plant foods. Flavonoids are said to contain antioxidant, anti-inflammatory, and even anticarcinogenic properties. Anthocyanins are a class of polyphenols. Polyphenols are found in many plant foods and contain various health benefits. Polyphenols are thought to be beneficial for heart health and may help treat other conditions like insulin resistance and inflammation. Although supplements are available, the best way to get anthocyanins is through food. A food-first approach to anthocyanins ensures better absorption and utilization of nutrients. However, supplements may be necessary in certain cases. Anthocyanins are found in many plant foods, most of which are fruits or vegetables. Plants that are rich in anthocyanins include:. Some foods, like baked goods, dairy products, and beverages may even be fortified with anthocyanins. You can also purchase anthocyanin-rich supplements, including tart cherry extract, blueberry extract , bilberry extract , and black raspberry extract. Fruits, vegetables, beans, and grains that are deep red, purple, or blue are generally rich in anthocyanins. You can also buy berry-based, anthocyanin-rich dietary supplements. Anthocyanin supplements are mostly available as various berry extracts. These may come in the form of capsules, soft gels, tablets, or gummies. Keep in mind that supplements containing anthocyanins typically have additional nutrients and ingredients. If you choose to take an anthocyanin supplement, you should also note that supplements are not regulated in the United States as strictly as drugs and conventional food products. Because of this, they can vary in quality and may contain ingredients you may not want. To better ensure quality and purity, look for products that have been independently certified by ConsumerLab, USP, or NSF International. Certification doesn't mean that supplements are safe or effective but that they contain the ingredients listed on the product label and in the advertised amounts. Anthocyanins are natural pigments in certain plants that give them their purple, blue, or red color. Anthocyanins are rich in antioxidants and other bioactive ingredients that may offer health benefits. Anthocyanin-rich foods are highly nutritious and an excellent part of a well-balanced diet, but it is still unknown if anthocyanin supplements provide any true benefits. If you're thinking about taking an anthocyanin supplement, talk with your healthcare provider first. Remember that supplements cannot cure or prevent any health condition and that nothing beats nutrition from whole food sources. Khoo HE, Azlan A, Tang ST, Lim SM.

Natural anthocyanins sources -
So how to add that extra touch to a food product without altering its quality and organoleptic characteristics? The answer is yes, and we are talking about anthocyanins! Anthocyanins are plant pigments belonging to the flavonoid group and are found naturally in many fruits, berries, vegetables, flowers and leaves in shades of purple, purplish red and blue.
They are particularly rich in anthocyanins: aubergines, berries such as blueberries and currants, beetroot, purple and red carrots and especially black grapes. The greater the intensity of the color, the greater the concentration of anthocyanins in the fruit.
In particular, enocyanin is obtained from black grapes, a completely natural dye derived from grape skins, which we will discuss in the next paragraph. The beneficial properties of anthocyanins are now well known, in fact they are very precious substances for health. Furthermore, anthocyanins would also have a positive effect on the capillaries of the eyeball, thanks to the beneficial effect they exert on the microcirculation.
As we have already anticipated, enocyanin is the pigment contained in black grapes. From a chemical point of view, enocyanin is a monoglucoside and the pigments it contains are the anthocyanidins of anthocyanins. This natural dye therefore belongs to the anthocyanin family and is obtained in Italy from the processing of the skins of Lambrusco, Ancellotta and Montepulciano grapes; precisely for this reason it can happen to hear improperly spoken of wine anthocyanins.
Commercially, enocyanin is presented as a liquid with shades ranging from red-purple to intense red-violet depending on the grapes of origin, known with the initials E Through a process of precipitation or more simply of separation and using very advanced extraction technologies, natural dyes are obtained in the range of browns, reds and purples, both in liquid and powder form.
Its uses in the food sector are very varied; in fact, enocyanin is used to naturally color foods and drinks such as:. Thanks to the high coloring power of enocyanin , the desired colors can be obtained even using minimal quantities , without thus altering the organoleptic qualities of the treated product.
Enocyanin also has excellent stability always making sure that the products or the dye itself are kept away from sources of light and heat.
Furthermore, enocyanin is easily soluble in water , alcohol and sugar solutions. However, it is not soluble in lipid solvents. It is not only from black grapes that high quality natural dyes are obtained, but also from red carrots , which are an excellent source of natural pigments for food use.
In fact, the anthocyanins of the red or purple carrot have a low pH and a good value for money , which allows to keep production costs lower. We have already mentioned that one of the great advantages offered by anthocyanins and grape and red carrot-based dyes is that they can be used in minimal quantities, without changing the taste and smell of the treated products.
Another great advantage of anthocyanins, however, is also that of being able to widely customize the color , to obtain specific shades. Geber collaborates with international producers and certified laboratories which, following specific customer requests, can develop a customized color to give a unique shade to each product.
The anthocyanin-based colors of grapes and red carrots are therefore an optimal solution for the preparation of foods that are not only beautiful, but also healthy, appetizing and good, both for humans and for the environment!
The pre-clinical, clinical and pharmaceutical applications are also discussed, to emphasize the consumer demands and medicinal value of anthocyanins. Since several decades, flavonoids have captured the attention of scientists worldwide. The popularity of flavonoids in the scientific world is due to their versatile applications, therapeutic uses and environmental significance.
They are reported to possess several beneficial pharmacological effects. Based on published reports, flavonoids exist in eight different classes and they are more than in number. These classes include anthocyanins, anthocyanidins, lipophilic flavones and flavonols, flavone and flavonol glycosides, chalcones, dihydrochalcones and aurones, flavanones and dihydroflavonols [ 1 , 2 ].
Anthocyanins occur in various parts of plants including flower petals, stems, leaves and fruits. They are polyphenolic pigments that range in colors from red to purple. Literature survey reveals the presence of more than anthocyanin compounds [ 3 , 4 ]. Anthocyanins have several phenyl groups in their structure and mostly occur in glycosylated form.
The anthocyanidins are reported to be less stable than anthocyanins [ 5 ]. The structural diversity of anthocyanins provides advantage to the chemical modifications that can be carried out.
The most reported structural modifications on anthocyanins include acylation. Routine consumption of anthocyanins is reported to be beneficial in preventing cardiovascular, neurological and metabolic disorders [ 7 ].
They are not essential constituents of diet but can be easily supplemented through intake of fruits and vegetables. There are no dietary intake reference levels established for anthocyanins till date. However, institutes worldwide recommend the use of anthocyanins for promoting good health.
Publications such as Dietary Guidelines for Americans have been published to create awareness among consumers about their health benefits [ 8 ]. A report published on the dietary intake of anthocyanins states that, on an average the female population has a higher intake of anthocyanins compared to males.
A report indicates that the intake of anthocyanins was found to be higher in white population compared to Hispanic and non-Hispanic other populations in the USA [ 9 ].
Traditionally, fruits especially berries have been recommended as rich sources of anthocyanins. Despite their long use in traditional medicine, the use of anthocyanins in western medicine is still awaited.
With their increasing popularity, the application of anthocyanins as a substitute to synthetic colors in food products is gaining acceptance. In the current chapter, the chemistry, pre-clinical, clinical and pharmaceutical uses are discussed in detail. The natural sources of anthocyanins and their traditional medicinal uses are also discussed in detail.
The natural sources of anthocyanins include fruits, flowers, leaves and roots of plants. The most widely consumed anthocyanin natural products include cherries, berries and cereals. Scientific reports reveal several anthocyanins and their derivatives isolated from natural sources.
A comprehensive list of some sources with specific anthocyanins is provided in Table 1. Anthocyanins occurring in flowers are observed to be more stable than the anthocyanins found in grapes. Studies that investigated the chemistry behind intensification and stability of grape wine color upon storage reveal that a cycloaddition reaction leads to the formation of 4-substituted anthocyanins.
These anthocyanins are suggested to be the possible reason for stability of wine color upon maturation. The grape varieties that contain 3,5-diglycosides produce wine of an inferior quality compared with the varieties that contain high levels of 3-monoglycosides [ 45 , 46 ]. The cycloaddition reaction leading to formation of 4-substituted anthocyanins was also observed in seeds of red currant [ 1 ].
Cereals form an important part of human diet and they are available in various colors ranging from red, yellow, purple and black. These colored cereals are a rich source of anthocyanins and include common cereals such as wheat, barley, sorghum, rice, maize, rye, oats, etc. Structures of some representative anthocyanins found in cereals, and fruits and flowers are represented in Figures 1 and 2 , respectively.
Structures of representative anthocyanins and their derivatives found in cereals. Structures of representative anthocyanins obtained from fruits and flowers.
Anthocyanins are naturally occurring pigments. They are phenolic compounds that are mostly hydroxy derivatives of flavylium salts or glycosides of methoxy derivatives.
Anthocyanins vary in forms based on the attachment of acids and hydroxyl groups to the sugar moieties within their structure. The anthocyanins found in plants include: cyanidin, delphinidin, pelargonidin, malvidin, peonidin and petunidin.
Of these, cyanidin 3-glucoside is the most widely found anthocyanin [ 51 ]. The anthocyanins have an ionic structure and thus their color in solution is pH dependent [ 52 ]. They possess colors in shades of blue as the solutions approach a neutral pH and a red color shade as the solutions are made acidic.
Lower pH values provide higher stability to anthocyanins. The flavylium cations increases the solubility of colored pigments in water at low pH.
With increase in protonation caused due to increase in pH, the concentration and stability of pigments reduces. Polymerization reactions are also reported to increase their color stability.
Purple-colored stable quinonoid anions are formed at neutral pH [ 53 ]. Plants synthesize anthocyanins and store them in vacuoles.
The colors of anthocyanins in the vacuoles will vary depending on the existing pH conditions. A general flavonoid pathway is used by plants for their synthesis. Chalcone isomerases convert naringenin chalcone to naringenin [ 54 ]. Naringenin then undergoes several hydroxylation steps to form anthocyanins.
A schematic representation of the anthocyanin formation pathway is provided in Figure 3. Biosynthesis of anthocyanins in plants. Traditionally anthocyanins from plants have been used for treatment of hepatobiliary issues such as hyperbilirubinemia, obstructed bile ducts and treatment of lack of appetite [ 55 ].
In this section several therapeutic uses of anthocyanins reported in literature are discussed. A list of the effect of anthocyanin treatment in disease conditions and the tested pathological markers is provided in Table 2.
Effect of anthocyanin treatment in disease conditions and the tested pathological markers. Anthocyanins act as good free radical scavengers due to the keto group with a conjugated double bond.
The high reactivity and instability of aglycones in their structure provides an advantage for anthocyanins in acting as antioxidant agents [ 61 ]. Glycosylation reactions reduce and diacylation reactions increase their free radical scavenging activity.
Anthocyanins have been investigated in various systems and models for their antioxidant effect. In a study investigating the formation of malondialdehyde after UVB irradiation, delphinidinglucoside and pelargonidinglucoside exhibited significant antioxidant effects [ 62 ].
Pelargonidin acts as an excellent hydroxyl radical scavenger, and delphinidin acts as a good oxygen radical scavenger. Studies also report cyanidin and cyanidinglucoside to possess inhibitory effects against oxidation of low-density lipoproteins LDL [ 63 ]. Angiogenesis is the process of development of new blood vessels with the help of endothelial cells.
Chemical mediators within the body angiogenic and antiangiogenic factors maintain the environment required for normal angiogenesis. Angiogenic factors include growth factors such as vascular endothelial growth factor VEGF , angiopoietin and fibroblast growth factor.
Antiangiogenic factors include factors such as thrombospondins. Disruption in the balance between these factors can lead to complications in disorders such as diabetes and cancer.
Reports published on evaluation of expression of VEGF reveal that colored berries due to their anthocyanin contents, reduce expression of VEGF and VEGF induced tube formation in ex-vivo models of human cell lines, under oxidative stress [ 64 ].
When high glucose concentrations were induced in human endothelial cells, anthocyanins from purple corn were found to inhibit expression of angiogenic factors [ 65 ].
Angiogenesis play a very critical role in proliferation of cancer cells. Reports suggest that anthocyanins extracted from berries have antiangiogenic effects in various cancer cell lines.
Blue berry, bilberry and black rice anthocyanins are reported to exhibit anti-invasive properties in breast cancer cells and in in-vivo animal models by reducing the expression of cyclooxygenase-2 gene [ 65 ]. Other mechanisms of action reported for anticancer effect of black rice include suppression of activation of mitogen-activated protein kinase MEK , and decreased expression of matrix metalloproteinase 2 MMP2 and matrix metalloproteinase 9 MMP9 [ 66 ].
A study of purple potato anthocyanins in CF-1 mice model reports the antitumor effect of its extracts in colon cancer by induction of cell-cycle arrest [ 66 ]. Anthocyanins from Cornus fruits are reported to induce insulin secretion in ex-vivo rodent beta cells. Cornus fruits are used in Traditional Chinese Medicine as antidiabetic agents.
It is reported that the property of inducing insulin secretion in anthocyanins may be due to the hydroxyl groups in their B-ring [ 67 ]. Anthocyanins reported to induce insulin secretion include delphinidinglucoside and pelargonidingalactoside.
Seoritae extract is reported to inhibit diabetic nephropathy by suppressing renal lipid deposition [ 68 ]. Anthocyanins from Bilberries act as antihyperglycemic agents by stimulating the adenosine monophosphate-activated protein kinase AMPK.
Bilberry extracts are also reported to improve visual function in patients suffering from diabetic neuropathy and glaucoma [ 69 ]. Neuroprotection is achieved by reduction in toxic effects and injuries caused to neurons due to oxidative reactions. Cyanidin glucosides are reported to inhibit DNA fragmentation and oxidative stress caused due to hydrogen peroxide formed in-vivo in human neuronal cells [ 70 ].
Tart cherry anthocyanins, when tested for neuroprotective activity in mice brain under oxidative stress inhibited generation of apoptosis-inducing factor [ 71 ]. CyanidinO-β- d -glucopyranoside and petunidinglucoside isolated from mulberry and black soybeans, are reported to exhibit neuroprotective activity in ex-vivo models.
They inhibit cerebral ischemia and cell death caused due to hydrogen peroxide induced oxidative stress [ 72 , 73 ]. Incorporation of anthocyanins as an ingredient in foods and pharmaceutical has undergone several challenges.
The prime issue with their use, is their stability and hence their effectiveness as a beneficial component in food and pharmaceutical. Anthocyanins are used as colorants in pharmaceuticals and food products as a substitute to synthetic colors.
Studies have compared the stability of anthocyanins as colors with synthetic colors and have found that the synthetic colors have better stability than anthocyanins.
In a study, stability of synthetic colors such as Carmoisine, Allura red and Ponceau were compared with natural anthocyanin colors, viz. enocyanin, dark carrot and cochineal. The results of the study indicate that at higher temperatures and higher pH conditions the stability of natural anthocyanins was much lower that the synthetic colors [ 74 ].
However, the beneficial effects of anthocyanins cannot be ignored due to their stability issue. In another study, the stability of freeze-dried powder of anthocyanin extract of wild blueberry was compared at various temperature values over a storage period of more than a month.
It was observed that the total anthocyanin content and the content of individual anthocyanins was most retained at 25°C and reduced significantly at higher temperatures [ 75 ]. A combination of ascorbic acid with anthocyanins from plant extracts was evaluated for stability under varying humidity, temperature and pH conditions in both freeze dried and solution form.
It was observed that in solution form the stability of the combination reduced with increase in pH and temperature. In freeze dried form the stability of the combination decreased with increase in humidity [ 76 ]. Commercially several yoghurt variants are available with a variety of fruits.
Some studies carried out on extracts of blackcurrant and wine grape extracts in yoghurt indicate that the fermentation process and addition of some probiotics reduce the stability of anthocyanins [ 77 , 78 , 79 ].
Microencapsulation is another technique tested for anthocyanin release and stability. In a cell line study carried out microencapsulated glycons and aglycons of some anthocyanins, glycons of anthocyanins were found to be more stable than the aglycon counterparts [ 80 ].
The conventional extraction methods are cost intensive and employ application of heat for extraction. Ground breaking research has been carried out in metabolic engineering of microbes for production of anthocyanins.
Cyanidin 3-O-glucoside has been successfully produced by E. However, its production at commercial scale poses challenges due to imbalances in the expression of other genes and lack of optimized transporters for extracellular secretion [ 81 ]. The merger of metabolic engineering with plant chemistry holds a promising future for anthocyanins and their application in food and drug industry.
The evidences provided through scientific studies till date, demonstrate the therapeutic benefits of anthocyanins. The anthocyanins are excellent natural sources of bioactive compounds that can help in treatment and prevention of many disease conditions. With the multidisciplinary research carried out in the last few years, anthocyanins have a promising future for their commercialization and application in the pharmaceutical and health foods sector.

The simplest answer is: because we taste food with our eyes even before our palate! This is why presenting a dish or drink in the right way is important for its success. Anthocyanins as natural dyes Anthocyanins are plant pigments belonging to the flavonoid group and are found naturally in many fruits, berries, vegetables, flowers and leaves in shades of purple, purplish red and blue.
The main benefits of anthocyanins are: Antioxidants Anti-inflammatory Anti-aging Anti-free radicals Beneficial effect on microcirculation aid for cellulite and water retention Protective effect of veins and capillaries Positive effect on the cardiovascular system Furthermore, anthocyanins would also have a positive effect on the capillaries of the eyeball, thanks to the beneficial effect they exert on the microcirculation.
What is enocyanin and how is it obtained: wine anthocyanins As we have already anticipated, enocyanin is the pigment contained in black grapes. Its uses in the food sector are very varied; in fact, enocyanin is used to naturally color foods and drinks such as: Pastry and bakery products Ice creams and sorbets Syrups Jams and marmalades Yogurt Liqueurs and spirits Fruit juices and soft drinks Wines in countries where it is allowed Thanks to the high coloring power of enocyanin , the desired colors can be obtained even using minimal quantities , without thus altering the organoleptic qualities of the treated product.
Anthocyanins are a type of water-soluble flavonoid. Flavonoids are a type of phytochemical, which are compounds found in many plant foods. Flavonoids are said to contain antioxidant, anti-inflammatory, and even anticarcinogenic properties.
Anthocyanins are a class of polyphenols. Polyphenols are found in many plant foods and contain various health benefits. Polyphenols are thought to be beneficial for heart health and may help treat other conditions like insulin resistance and inflammation.
Although supplements are available, the best way to get anthocyanins is through food. A food-first approach to anthocyanins ensures better absorption and utilization of nutrients.
However, supplements may be necessary in certain cases. Anthocyanins are found in many plant foods, most of which are fruits or vegetables. Plants that are rich in anthocyanins include:.
Some foods, like baked goods, dairy products, and beverages may even be fortified with anthocyanins. You can also purchase anthocyanin-rich supplements, including tart cherry extract, blueberry extract , bilberry extract , and black raspberry extract.
Fruits, vegetables, beans, and grains that are deep red, purple, or blue are generally rich in anthocyanins. You can also buy berry-based, anthocyanin-rich dietary supplements. Anthocyanin supplements are mostly available as various berry extracts.
These may come in the form of capsules, soft gels, tablets, or gummies. Keep in mind that supplements containing anthocyanins typically have additional nutrients and ingredients. If you choose to take an anthocyanin supplement, you should also note that supplements are not regulated in the United States as strictly as drugs and conventional food products.
Because of this, they can vary in quality and may contain ingredients you may not want. To better ensure quality and purity, look for products that have been independently certified by ConsumerLab, USP, or NSF International.
Certification doesn't mean that supplements are safe or effective but that they contain the ingredients listed on the product label and in the advertised amounts.
Anthocyanins are natural pigments in certain plants that give them their purple, blue, or red color. Anthocyanins are rich in antioxidants and other bioactive ingredients that may offer health benefits. Anthocyanin-rich foods are highly nutritious and an excellent part of a well-balanced diet, but it is still unknown if anthocyanin supplements provide any true benefits.
If you're thinking about taking an anthocyanin supplement, talk with your healthcare provider first. Remember that supplements cannot cure or prevent any health condition and that nothing beats nutrition from whole food sources.
