Abstract

The invention discloses a method for improving the dissolubility of proanthocyanidins of grape seed extract in a press-shear assisted interaction manner, and belongs to the technical field of extraction of active ingredients of plants. The method comprises the following steps: cleaning, drying and crushing grape seeds to obtain coarse grape seed powder; performing ultrafine grinding on the coarse grape seed powder and a physical auxiliary to obtain press-shear assistant powder; removing grease in the press-shear assistant powder by virtue of petroleum ether, performing ultrasonic ethanol extraction, distilling an extracting solution under reduced pressure after ultrasonic extraction, and concentrating dry powder to obtain the grape seed extract; detecting the content of the proanthocyanidins in the extract to determine the release rate of the target component by virtue of iron salt catalytic colorimetry. Compared with the prior art, the method has the advantages that the proanthocyanidins of grape seeds are extracted in the press-shear assisted interaction manner, the dissolubility of the proanthocyanidins in an aqueous solution can be effectively improved in a press-shear assistant powder state, and the precipitation rate of the proanthocyanidins is further increased.

Description

technical field [0001] The invention belongs to the technical field of extraction of plant active components, and relates to the extraction technology of grape seed components of new resource food, in particular to the extraction method of functional active components of grape seeds. Background technique [0002] Grapes are one of the largest fruit crops in the world with an annual production of 69 million tons. Grape seeds make up 5% of most grapes and are a major by-product of the grape processing industry such as grape juice and wine. Today, grape seed extract (GSE) is gaining increasing interest from scientists, nutritionists and consumers due to reports of potential health benefits of grape seed for a variety of health disorders. Based on their potential antioxidant, anticancer, antibacterial, antiaging, antihepatotoxic, and anti-inflammatory activities, they are widely used as dietary supplements and certified safe by the Food and Drug Administration. The beneficial ...
