Method for preparing gingko powder

Abstract

The invention provides a method for preparing gingko powder. The method includes the following steps of 1) rinsing, wherein fresh mature gingko fruits without mildewing are picked, outer shells are removed, and the obtained gingko fruits are cleaned; 2) heating, wherein the cleaned gingko fruits are rapidly heated till inner shells are cracked; 3) peeling, wherein the obtained gingko fruits are poured into a gingko peeling machine, the shells and inter peels are smashed, the inner peels are blown away through a draught fan, fruit nuts are taken out, nut cores are removed, and the obtained fruit nuts are cleaned; 4) color protecting, wherein the obtained fruit nuts are smashed, soaked with a color protecting solution and filtered, and coarse gingko powder is obtained; 5) enzymolysis, wherein a solvent, a surfactant and enzymes are respectively added for enzymolysis; 6) extracting, wherein microwave-assisting extracting is carried out, and acid is absorbed with strong base; 7) adsorbing, wherein an adsorbent is added, and filtering is carried out; 8) sterilizing, wherein filtered liquor is physically sterilized; 9) drying, wherein vacuum concentration and drying are carried out; 10) smashing, wherein the obtained product is smashed and sieved, and the gingko powder is obtained. The gingko powder prepared with the method is safe, low in toxicity and rich in nutrient ingredient, and products with different kinds of flavor can be prepared by adding different regulators to meet the demands of various persons.

Description

technical field [0001] The invention relates to the preparation of ginkgo products, in particular to a processing method of ginkgo powder, and belongs to the field of food and medical raw materials. Background technique [0002] Ginkgo fruit, also known as ginkgo, is recorded in the Compendium of Materia Medica: "Ginkgo is edible and medicinal, and when eaten, it nourishes the heart and nourishes qi, nourishes the kidney and lungs, astringent essence and essence, and prolongs life; when used as medicine, it can relieve cough and asthma." Modern pharmacology proves that it has physiological effects such as lowering cholesterol, improving cerebral circulation, relieving spasm, and inhibiting bacteria, and has high edible and medicinal value. [0003] my country's ginkgo is widely distributed, and more than 20 provinces and cities (districts) have natural distribution of ginkgo. Among them, Taizhou, Jiangsu and Tancheng, Shandong account for about 70%, with an annual output of ...

Problems solved by technology

[0004] At present, the methods for removing toxins are mainly: CN105341628A etc. adopt simple heating method, high temperature and long time are easy to destroy active substances; CN1374302A etc. use organic solvents such as methanol and petroleum ether to repeatedly extract ginkgo leaves, and the solvent cost consumption is relatively high; CN101628018A and CN105901476A etc. adopt The fermentation method reduces the toxic components of ginkgo leaves and ginkgo fruit, the fermentation time is longer and the toxin removal is not complete; CN103960555A etc. adopt the strong alkali method for deacidification, and the loss of active substances is large; CN101531590A and CN102614229A etc. adopt the macroporous resin adsorption method, the amount of resin Many, not suitable for industrial production
