The invention discloses freeze-dried powder of fruit and vegetable extracts. Fruits and vegetables are taken as raw materials, a low-temperature extraction technology is adopted in the whole process, and obtained extracts keep natural color, flavor and taste of the fruits and the vegetables 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 freeze-dried powder of fruit and vegetable extracts is prepared, contains more nutritional substances and bioactive substances and is high in function, good in anti-freezing effect and solubility and low in cost.

The invention discloses a functional compound protein composition and a preparation method thereof. According to the functional compound protein composition and the preparation method thereof, soybean protein isolate, whey protein concentrate and phospholipids are utilized as main raw materials; low-temperature processing is performed on stevia rebaudiana so as to prepare a stevia rebaudiana extract to preserve active ingredients and biologically active ingredients of the stevia rebaudiana to the maximum extents; the prepared stevia rebaudiana extract is high in extraction rate, pure in flavor, natural in color and luster, and free of liquorice smell; the stevia rebaudiana extract and the main raw materials are scientifically compounded, and antifreeze polypeptides, dietary fiber powder, bee pupae enzymatic hydrolysate and wheat malt flour are added, so that the functional compound protein composition is prepared; and the prepared functional compound protein composition is appropriate in taste, good in solubility, whole in nutrition, good in biological activities and suitable for a wide range of people. The preparation method adopts a non-thermal processing technology, so that the preparation method is high in work efficiency, small in energy consumption, friendly to the environment and free of pollution; moreover, the preparation method reduces introductions of food additives and chemical additives, so that safety of the foods is effectively improved, qualities of the foods are improved and production costs are reduced. The preparation method of the functional compound protein composition realizes low-carbon production target, and is capable of realizing scale development and industrialized development.

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.
