Abstract

The invention discloses instant medicinal and edible food extract freeze-dried powder. Medicinal and edible foods are used as raw materials, a low-temperature extraction technology is adopted in the whole process, and an obtained extract furthest reserves natural color, natural flavor and natural mouth feel of the medicinal and edible foods; in the vacuum freeze drying process of the extract, an anti-freezing agent which is prepared from natural plant raw materials and has remarkable anti-freezing effects is used for replacing conventional existing cryoprotectants, so that further freezing loss caused by a freeze-drying technology is greatly reduced, and the biological activity and the nutritive value of the extract freeze-dried powder are effectively improved; besides, when the extract, functional dietary fiber powder, prebiotic factors and lactobacillus plantarum powder are scientifically compounded, the medicinal and edible nutrition balance, the functionality, the solubility and the prebiotics of the extract freeze-dried powder are obviously strengthened, the guarantee period of products is prolonged, and finally the instant medicinal and edible food extract freeze-dried powder which is high in content of nutrient substances, high in content of biological active substances, powerful in functions, good in anti-freezing effects, good in solubility and low in cost is prepared.

Description

technical field [0001] The invention relates to the preparation of freeze-dried powder, in particular to an instant freeze-dried powder of food extracts of the same origin as medicine and food and a preparation method thereof. Background technique [0002] Freeze-dried powder is a sterile powder obtained by freezing the medicinal liquid into a solid state in a sterile environment, and sublimating and drying the water in a vacuum. Freeze-drying is an effective method for drying heat-sensitive products and substances that need to maintain biological activity. This method is to freeze the moisture contained in the product to be dried at a low temperature, and then dry it in a vacuum environment, so that the moisture is directly sublimated from a solid state to water vapor and removed from the product to make the product active and dry. This method effectively prevents changes in the physical, chemical and biological properties of the product, and causes less damage to the stru...
