Abstract

The present invention discloses active medicinal and edible food extract freeze-dried powder. The preparation method uses medicinal and edible food as raw materials and a low temperature extraction technology in the whole process, and the obtained extract maximally maintains the nature color and luster, tastes and mouthfeel of the medicinal and edible food. In the vacuum freeze-drying process of the extract, an antifreeze agent prepared by using natural plant raw materials and having significant antifreeze effects is used to replace traditional and existing cryoprotectants, which further greatly reduces the freeze losses caused by the freeze-drying technology and effectively improves the biological activity and nutritional value of the extract freeze-dried powder. The antifreeze agent is scientifically combined with functional dietary fiber powder, probiotic factors and lactobacillus plantarum powder, which significantly enhances the medicinal and edible nutritional balance and functionality, solubility and probiotic properties of the extract freeze-dried powder, and extends the shelf life of the products. Finally, the active medicinal and edible food extract freeze-dried powder is obtained, high in contents of the nutrients and bioactive substances, strong in functions, good in anti-freeze effects and solubility, 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 active medicine and food homologous food extract 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 char...
