Method for extracting grape anthocyanins

The invention discloses a method for extracting grape anthocyanins, which comprises the following operation steps: (1) taking a grape raw material, adding an extractant and standing, wherein the extractant is prepared by mixing ethanol and furan, and the volume ratio of ethanol to furan being (1 to 2):(0.5 to 1.5); (2) placing the matter obtained in the step (1) by standing at subzero 8 DEG C to subzero 1 DEG C, taking out, heating to 40 DEG C, and then heating to 65 to 85 DEG C, and maintaining the temperature for extraction for 1 to 3 hours, so as to obtain the grape anthocyanins. By adoption of the method disclosed by the invention, the extractant can extract more anthocyanins contained in grapes, the method is simple and time-saving, and industrialized production is easy to realize. 本发明公开了种葡萄花青素的提取方法，包含以下操作步骤：(1)取葡萄原料，加入提取剂，静置；其中，所述的提取剂由乙醇和呋喃混合而成，按照体积比乙醇：呋喃＝1～2:0.5～1.5；(2)将步骤(1)中静置后所得物质放入-8～-1℃放置，取出，升温至40℃后，再升温至65～85℃，保持该温度提取1～3小时，即得。采用本发明方法后提取剂能够提取更多葡萄中含有的花青素，且本发明采用简洁，耗时短，更容易实现工业化生产。
