Abstract

The invention provides red ginseng whole powder prepared through a composite enzymolysis method assisted by an extrusion technology and a preparation method. Red ginseng is pretreated through the extrusion technology, the red ginseng is subjected to enzymolysis through the composite enzymolysis method, and the prepared red ginseng whole powder is very high in total saponin content, soluble dietary fiber content and protein content; the nutritional value is more comprehensive and richer, and small molecules after enzymolysis are easier to absorb by a human body; the product is good in solubility, faint yellow in color and luster, free of earthy smell and good in sensory value; and the comprehensive utilization of ginseng products with high added value is realized, the obtained red ginseng whole powder can be used as a food base material, and a new method is provided for the development of ginseng food.

Description

technical field [0001] The invention provides a composite enzymolysis method assisted by extrusion technology to prepare red ginseng whole powder, and also discloses the preparation method, which belongs to the technical field of food processing. Background technique [0002] Red ginseng is the dried root and rhizome of the cultivated product of Araliaceae ginseng after steaming. During the high-temperature steaming process of red ginseng, a series of physical and chemical changes will occur, which makes red ginseng have higher nutritional value than ginseng. The recognized active ingredients of ginseng mainly include ginsenosides, ginseng polysaccharides and ginseng proteins. How to extract these active ingredients more efficiently and then add them to food is a practical problem in the development of ginseng series products. [0003] At present, there are mainly two kinds of common ginseng powder base materials, one is directly obtained by physical methods, such as extru...
