Several studies have shown that anthocyanin stability increases with decreased water content, i.e., decreasing water activity (aw) (Wrolstad, 2000). Dry anthocyanin powders (aw < 0.3) are stable for several years when stored in hermetically sealed containers (Jackman and Smith, 1996). This property is advantageous when anthocyanins are produced into dry products and powders. Zajac et al. (1992) reported anthocyanin losses of 14% after 15 months of storage of a dry powder from black currant extracts at 20°C. When starch syrup or maltodextrins were included as carriers during the drying of the extracts, the anthocyanin losses were reduced to 2% and 3%, respectively.

The percolate is concent ra ted by evaporation until tlic residue has the consistency of a thin syrup and is then poured, with constant stirring, into 100 ml water containing I ml llCl (38%), and precoofed to a temperature below 10°C. The precipitate is decanted and washed with two 100-ml portions of cold water 0.1 g dried resin is dissolved in 2 ml methanol, and 20 [d is used for TLC.
