Abstract

Anthocyanins represent a group of ubiquitous water-soluble pigments found in most flowers and fruits. These dyes are responsible for impressive colors in the range from orange-red to purple-blue, and thus are highly interesting for many applications. In this chapter, an explanation of the basic reactions leading to molecular rearrangement and loss of color of these dyes is given. Dependent on pH, a series of reactions including proton transfer, hydration, tautomerization and isomerization lead to irreversible formation of the colorless chalcones. Strategies for color stabilization for different applications are presented and examples for commercial products and processing are given.
