Efficient extraction method for blueberry anthocyanin

Abstract

The invention discloses an efficient extraction method for blueberry anthocyanin. According to the method, blueberry fruits or blueberry leaves are taken as raw materials for extracting the blueberry anthocyanin and the method comprises extraction and purification of a blueberry anthocyanin crude extract and specifically comprises the following steps of carrying out enzymolysis and alcohol extraction in turn to obtain the blueberry anthocyanin crude extract, then purifying the blueberry anthocyanin crude extract, degreasing by extraction and removing impurities with macroporous resin to obtain the refined blueberry anthocyanin. According to the method disclosed by the invention, solvent extraction and enzyme extraction are simultaneously combined, enzymolysis is firstly used for improving the juice yield of the blueberry anthocyanin and a solvent is further used for extracting the blueberry anthocyanin. By adopting the extraction method, the extraction time can be greatly shortened, the active ingredients can be extracted to the greatest extent, and the extraction rate can be significantly improved; furthermore, the operation is simple and easy to operate, the parameters of the production process are stable, the product quality is stable, and the extraction method is suitable for industrial production; and in addition, the highest content of an extracted and purified blueberry anthocyanin fine product can achieve 49.6%, and the application value is very high.
