Effects of Extraction Conditions on Bioactive Anthocyanin Content of Vaccinium Corymbosum in the Perspective of Food Applications

2012

Abstract Bioflavonoids, in particular anthocyanins have made the topic of many scientific research, mainly for two reasons: their beneficial effects on human health and applications as potential sources of natural food dyes. Natural extracts of these pigments may also find useful application for textiles dying, as an eco-friendly alternative to synthetic dyes. The aim of the present paper was to apply conventional extraction procedures in order to isolate an enriched crude extract of pigments from highbush blueberries (Vaccinium corymbosum L.). Water, hydroalcoholic solution and acidified alcoholic solvent were tested to extract anthocyanins by a discontinuous process. Also, temperatures of…
