A method for preparing water-solubility ginkgo powder

Abstract

The invention relates to a production method of a water soluble gingko powder, and belongs to the gingko processing technical field. The invention takes fresh gingko as the raw material, the gingko seeds are crushed with water after being shelled, the gingko starch and the destarch gingko solution are respectively obtained through precipitation separation, the gingko starch obtains the gingko starch hydrolyzed solution through the enzymolysis of amylase and pullulanase together, and the gingko starch hydrolyzed solution and the destarch gingko solution adopt homogenization treatment and spray drying after being mixed, so as to produce a water soluble gingko powder of the residual of non-cyanide. The water soluble gingko powder holds the gingko fragrance and the nutrition component. And thereby the invention has vital significance to the comprehensive utilization of the gingko resources.

Description

technical field [0001] The invention discloses a production method of water-soluble ginkgo powder, belonging to the technical field of ginkgo processing. Background technique [0002] Ginkgo biloba, also known as ginkgo, is a unique rare fruit in my country and has high economic value. Ginkgo fruit is composed of fleshy outer testa, bony middle testa, membranous inner testa, and seed kernel. According to the "Compendium of Materia Medica": "Cooked food warms the lungs, nourishes qi, calms asthma and cough, reduces stool, stops white turbidity; raw food reduces phlegm, disinfects and kills insects." Modern science proves that the starch content in ginkgo seeds is 30%-35%, protein 5%-6.4%, fat 2%-2.4%, polysaccharide 0.87%-1.1%, water about 55%, and also contains selenium, phosphorus, Minerals and vitamins such as iron, carotene, riboflavin, thiamine and niacin, and various physiologically active substances have anti-Escherichia coli, diphtheria bacillus, staphylococcus, tub...

Problems solved by technology

The above products are directly oriented to the beverage terminal market, and the product shelf life is limited, making it difficult for enterprises to develop the market; in addition, the industrial chain is short, and the living space of enterprises is limited; The contradiction between the production of Ginkgo biloba and the limited processing capacity of enterprises, in the face of this situation, it is necessary to increase the deep processing of Ginkgo biloba

[0004] After the novelty investigation, there is no production method similar to the novelty investigation project at home and abroad (in the production of ginkgo dry powder, the ginkgo starch is first separated, and α-amylase and pullulanase are used to treat it with controlled enzymatic hydrolysis technology, and the processed modified Ginkgo starch is mixed with destarched Ginkgo solution, and finally spray-dried to form Ginkgo dry powder), and the production and research of Ginkgo dry powder with the same application range (medicinal food additive products) are published in the literature.
