Abstract

The invention discloses blueberry liposome freeze-dried powder and a preparation method thereof. The preparation method of the freeze-dried powder comprises the following steps: stirring and uniformly mixing main materials, namely blueberry and bee milk and auxiliary materials which comprise lyase, a nano-carrier, a lipidosome material, a solubilizing agent and a filling agent with injection water according to a ratio, homogenizing and carrying out ultrasonic treatment to prepare a slurry, putting the slurry into a dish and flattening, freeze-drying to obtain a semi-finished product, then crushing and sieving the semi-finished product to obtain finished blueberry liposome freeze-dried powder. Due to the adoption of nanometer immobilized enzyme technology in the preparation process of the blueberry liposome freeze-dried powder, the bioavailability of the active ingredients is greatly improved; due to the adoption of sealing function of the lipidosome material and the substances sensitive to heat, the damage to the active ingredients which comprise anthocyanin in fresh blueberry fruits and the bee milk are avoided; meanwhile, due to the adoption of homogenization and ultrasonic treatment in the preparation process, the freeze-drying process and parameters are further optimized; the content of the anthocyanin which is taken as an effective nutrition component in the product is increased by over 20%.

Description

technical field [0001] The invention belongs to a blueberry freeze-dried powder and a preparation method thereof, in particular to a blueberry liposome freeze-dried powder and a preparation method thereof. Background technique [0002] Blueberry fruit is rich in nutrients and is one of the five healthy fruits recommended by the World Food Organization. It has high economic value and broad development prospects. Nutrients include: anthocyanins, total and organic acids, phenolic acids, superoxide dismutase, pectin, pterostilbene. Blueberries contain a large amount of anthocyanins, the content of which is the highest among all fruits and vegetables. Its antioxidant properties are 50 times higher than vitamin E and 20 times higher than vitamin C. Blueberries can reduce eye fatigue And improve night vision, prevent cataract, protect capillaries and anti-oxidation, inhibit platelet coagulation, prevent the formation of thrombus and arteriosclerosis, enhance the function of joints...
