Abstract

The invention provides an extraction method of selenoprotein in cardamine violifolia, the selenoprotein obtained by the extraction method and application of the selenoprotein. The extraction method comprises the following steps of carrying out enzymolysis on the cardamine violifolia by adopting enzymes including cellulase to obtain a cardamine violifolia enzymatic hydrolysate; and concentrating the cardamine violifolia enzymatic hydrolysate, and drying the concentrated cardamine violifolia enzymatic hydrolysate. According to the method disclosed by the invention, the selenoprotein in the cardamine violifolia is extracted through enzymolysis of the enzymes including the cellulase, so that nutritional ingredients in the cardamine violifolia are not damaged, the efficiency of extracting the selenoprotein through enzymolysis is high, the yield of the selenoprotein is relatively high, the protein content in the selenoprotein is high, the content of total selenium is high, and the total selenium is organic selenium; and in addition, the extraction method is simple, efficient, low in cost, environmentally friendly and easy for large-scale industrial production.

Description

technical field [0001] The invention relates to the technical field of biological extraction, and in particular to a method for extracting selenoproteins in broken Viola leaves, selenoproteins obtained by the extraction method and applications thereof. Background technique [0002] In recent years, studies have found that the genus Myrina has a super selenium-accumulating ability. At present, as the public's understanding of the relationship between selenium and health is getting deeper and deeper, the research on selenoproteins in Viola sativa has gradually become a hot spot. The main form of selenium in Violet-leaf catkins is organic selenium. There are a few patents and literature reports on the extraction and preparation of selenoproteins from Viola-leaf catkins. [0003] The existing technology for extracting selenoproteins in Viola leaf broken rice chestnuts generally adopts hot acid solution extraction method or alkaline solution extraction method, which takes a long...
