Natural Food Pigments and Colorants
Current Opinion in Food Science, 2016The natural color of foods is due primarily to carotenoids, anthocyanins, betanin and chlorophylls, either as inherent food constituents or as food or feed additives. These compounds have drawn considerable attention in recent years, not because of their coloring properties, but due to their potential health-promoting effects.

This introductory chapter provides a working definition of ‘natural’ pigments. The greater part of the chapter consists of a survey of pigmented compounds found in biology. Two systems of classification are adopted, one based on structural affinities, the second based on the natural occurrence of the pigment in biology.
