Anthocyanin research paper

Abstract Anthocyanin pigments and associated flavonoids have demonstrated ability to protect against a myriad of human diseases, yet they have been notoriously difficult to study with regard to human health. Anthocyanins frequently interact with other phytochemicals to potentiate biological effects, thus contributions from individual components are difficult to decipher. The complex, multicomponent structure of compounds in a bioactive mixture and the degradation of flavonoids during harsh extraction procedures obscure the precise assignment of bioactivity to individual pigments.

Research over the past decade has produced incontrovertible evidence for a vast array of health benefits arising from the consumption of fruits and vegetables.

In an endeavor to identify the active health-promoting ingredients, many researchers have focused on the properties of the flavonoids, a large class of phenolic compounds that is abundant in such foods.

Most prominent among the flavonoids are the anthocyanins—universal plant colorants responsible for the red, purple, and blue hues evident in many fruits, vegetables, cereal grains, and flowers. Represented by over molecular structures as identified to date, anthocyanins are of particular interest to the food colorant industry due to their ability to impart vibrant colours to the product.

Now it seems highly likely that they also enhance the health-promoting qualities of foods. Anthocyanins were incorporated into the human diet many centuries ago.

They were components of the traditional herbal medicines used by North American Indians, the Europeans, and the Chinese, and were habitually derived from dried leaves, fruits berriesstorage roots, or seeds.

Anthocyanin-rich mixtures and extracts though not purified compounds have been used historically to treat conditions as diverse as hypertension, pyrexia, liver disorders, dysentery and diarrhoea, urinary problems including kidney stones and urinary tract infections, and the common cold.

They have even been purported to yield improvements to vision and blood circulation. Recent studies using purified anthocyanins or anthocyanin-rich extracts on in vitro experimental systems have confirmed the potential potency of these pigments.

Demonstrable benefits include protection against liver injuries; significant reduction of blood pressure; improvement of eyesight; strong anti-inflammatory and antimicrobial activities; inhibition of mutations caused by mutagens from cooked food; and suppression of proliferation of human cancer cells.

Along with other phenolic compounds, they are potent scavengers of free radicals, although they can also behave as pro-oxidants.

Because of their diverse physiological activities, the consumption of anthocyanins may play a significant role in preventing lifestyle-related diseases such as cancer, diabetes, and cardiovascular and neurological diseases.


We do not know, for example, whether these apparent health benefits stem from anthocyanins alone, or from their synergistic interactions with other phenolic compounds.

Are the health-promoting qualities of anthocyanin-phenolic mixtures preserved across the various food systems? What is the fate of anthocyanin molecules after consumption?

Are the health-protective qualities observed in in vitro studies also displayed in vivo? If so, what might be the mechanism of the biological activity of anthocyanins?

The Third International Workshop on Anthocyanins organized by the Cooperative Research Centre for Bioproducts and Food Science Australia in Sydney, Australia, January 27—29,provided a forum for discussing the nutritional, physiological, and therapeutical functions of anthocyanins, and the opportunities for development of novel anthocyanin-based functional foods in compliance with regulatory requirements.

Through scientific presentations and dialogue among researchers, industry managers, and invited consumers, one aim of the workshop was to popularize the application of anthocyanins as natural food colorants with nutraceutical qualities.

Indeed, insightful comparisons were drawn between the effects of anthocyanins on animal cells and their native functions in plant cells. Display and degustation of anthocyanin-based food products was provided by Wild GermanyNutrinova Australia Ltd, Kingfood Australia Ltd, Tarac Technologies Ltd Australiaand The Natural Confectionery Co Australiaand served as an encouraging example to both researchers and industry managers through their search for novel anthocyanin-based food products promoting good health.

The presentations were accompanied by 26 posters. It reflects the diversity in presentations and discussion, and aims to disseminate information gathered during the workshop.The anthocyanin pigments that provide the "blood" color of blood oranges are not produced in significant amounts unless the fruit is exposed to cold conditions during its development or post-harvest.

A type of flavonoid called anthocyanin gives blueberries many of their health benefits. Flavonoids are plant compounds that often have a powerful antioxidant effect.. Anthocyanin is responsible.
