Abstract

The invention relates to the technical field of probiotics processing, and particularly discloses a preparation method of probiotics compound freeze-dried powder. The preparation method comprises thefollowing steps: step 1, preparing fruit and vegetable powder; step 2, culturing probiotics; step 3, carrying out mixing and stirring; and step 4, performing freeze-drying treatment; wherein the fruitand vegetable powder is prepared from the following raw materials in parts by weight: 4-6 parts of sweet potatoes, 5-12 parts of corn, 3-9 parts of common yam rhizomes, 5-9 parts of apples, 8-14 parts of strawberries and 4-8 parts of kiwi fruits; and compound probiotics includes: 1-3 parts of Bifidobacterium animal, 6-8 parts of Bifidobacterium lactis, 3-5 parts of Lactobacillus rhamnosus, 8-12 parts of Lactobacillus reuteri, 2-6 parts of Lactobacillus brevis, 6-10 parts of Lactobacillus fermentum and 3-6 parts of Lactobacillus acidophilus. The invention overcomes the defects of the prior art, and protective agents and the fruit and vegetable powder are added into the probiotics, on one hand, the survival number of probiotics is increased, on the other hand, the fruit and vegetable powderalso has the function of coordinating intestines and stomach; and the preparation method can improve the quality of the product and prolong the shelf life of the product.

Description

technical field [0001] The invention relates to the technical field of probiotic processing, in particular to a preparation method of probiotic composite freeze-dried powder. Background technique [0002] Probiotics are a type of active microorganisms that are beneficial to the host. They colonize the human intestinal tract and reproductive system, which can improve the host's micro-ecological balance and exert beneficial effects. Probiotic freeze-dried powder is a probiotic product obtained by freeze-drying technology. The drying of probiotics is basically carried out at a temperature below 0°C, generally not exceeding 40°C, so as to fully maintain the properties and activity of the probiotics themselves. [0003] The existing probiotic freeze-dried powder has probiotics that are easy to die, the number of viable bacteria in the freeze-dried powder is low, and the effect is unstable, resulting in unstable product quality and short shelf life, which cannot meet the needs of...
