| The use of natural pigments as colorants is a trend in food technology because of the safety hazard and long-term repercussions on health from the chemically synthetized pigments. Anthocyanins are flavonoid pigments with a general C6single bondC3single bondC6 structure widely spread in fruits, flowers, leaves, and other vegetal tissue. The color of natural anthocyanins covers most of the visual spectra from yellow-orange to blue-violet so they are a very interesting tool to improve the color of many foods and beverages. Also, flavonoids, being polyphenol molecules, have an interesting repercussion on human health as antioxidants. The stability of anthocyanins depends on several parameters, such as pH, temperature, and oxidative conditions, but they are normally quite stable in acidic media. A lot of research has been done on stability of anthocyanins and derived pigments. The present chapter describes the nature and properties of anthocyanins detailing the main natural sources and how these molecules can be used as pigments in beverages. | |
