Abstract

The invention discloses medicine and food homologous food extract freeze-dried powder with high nutrition value. Extracts obtained from medicine and food homologous food serving as a raw material with a low-temperature extraction process in the whole process keep the natural color, flavor and taste of the medicine and food homologous food to the greatest extent; an anti-freeze agent which is prepared from natural plant raw materials and has a remarkable cryoprotective effect replaces traditional and existing cryoprotective agents in the vacuum freeze drying process of extracts, the freeze loss caused by a freeze-drying process is further greatly reduced, biological activity and nutritional value of the freeze-dried powder of the extracts are effectively improved, the freeze-dried powder of the extracts is scientifically compounded with functional dietary fiber powder, prebiotic factors and lactobacillus plantarum powder, the medicine and food nutrition balance property as well as functionality, solubility and the probiotic property of the freeze-dried powder of the extracts is remarkably improved, the guarantee period of a product is prolonged, and finally, the medicine and food homologous food extract freeze-dried powder which contains more nutritional substances and bioactive substances and is strong in function, good in anti-freezing effect and solubility, low in cost and high in nutrition value is prepared.

Description

technical field [0001] The invention relates to the preparation of freeze-dried powder, in particular to a freeze-dried powder of food extract with high nutritional value 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 structure and characterist...
