Abstract

The invention discloses extract frozen-dried powder of fruit and vegetable medicine-food-homologous food.The fruit and vegetable medicine-food-homologous food serves as the raw material, the low temperature extraction technology is adopted for the whole process, and obtained extract maintains natural color, lustre, flavor and mouthfeel of the food raw material to the maximum extent; in the vacuum freeze-drying process of the extract, an antifreeze agent which is prepared from natural plant raw materials and has a remarkable antifreezing effect replaces traditional and existing cryoprotectant, freezing losses caused by the freeze-drying technology are further greatly reduced, biological activity of the extract frozen-dried powder is effectively improved, nutritive value of the extract frozen-dried powder is effectively raised, the extract frozen-dried powder is scientifically compounded with functional dietary fiber powder, health-care factors and lactobacillus plantarum powder, medicine-food nutrition balance, functionality, dissolvability and health care performance of the extract frozen-dried powder are remarkably enhanced, the shelf life of a product is prolonged, and the extract frozen-dried powder of the fruit and vegetable medicine-food-homologous food is finally obtained, wherein the food is high in nutrient substance content, biologically active substance content, great in function, good in antifreezing effect and dissolvability and low in cost.

Description

technical field [0001] The invention relates to the preparation of freeze-dried powder, in particular to a freeze-dried powder of fruit, vegetable, medicine and food homologous food extracts 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 struct...
