Polyphenols as Natural Food Pigments: Changes During Food Processing
The colors of the foods and beverages contribute not only to their appearance but also to their agreeableness, which linked to both taste and flavor. Polyphenols, particularly flavonoids, are important pigments for determining food color, similar to carotenoids and chlorophylls. Food and beverages contain a mixture of intact pigments, which are derived from raw materials and artificial pigments that are generated by chemical and enzymatic reactions during processing and storage. This study provides and overview of the characteristics and contributions of native polyphenol pigments from plants materials, as well as those generated by chemical and enzymatic reactions during food and beverage productions.
