Abstract
The ethanol extraction of blueberry pigment from blueberry was studied in this paper. The results showed that the optimal ethanol concentration, extraction time, extraction temperature, pH value and the ratio of solid to liquid were 80%, 30 min, 30℃, 2 and 1: 10, respectively, under which the yield of the extracted pigment achieved 92.4%.
