Abstract
The invention discloses a fruity probiotic yogurt slice containing antifreeze sericin peptide. The raw materials for preparing the fruity probiotic yogurt slice comprise 10-14 parts of skimmed milk powder, 2-5 parts of sucrose, 1-3 parts of sericin peptide, 1-4 parts of fruit material, 0.1-0.6 part of lyophilized active probiotics and 0.1-0.4 part of magnesium stearate. The invention further discloses a method for preparing the product which is the fruity probiotic yogurt slice. The method mainly comprises the following steps of: preparing a skimmed-milk food-grade culture medium, fermenting the probiotics, adding the antifreeze sericin peptide, freezing and drying fermented milk in vacuum, and pressing powder into slices. As the fruity probiotic yogurt slice contains the antifreeze sericin peptide and the lyophilized fruit powder which is rich in the vitamin B group, the number of the probiotics in the fruity probiotic yogurt slice can be increased, the retention time of the activity of the probiotics can be prolonged, and the taste, flavor and nutritional and healthcare values of the fruity probiotic yogurt slice can be improved. The fruity probiotic yogurt slice can serve as a functional food for supplementing the vitamin B group, improving the immunity and promoting the intestinal health.
Description
technical field [0001] The invention relates to a probiotic yogurt tablet and a preparation method thereof, in particular to a fruity yogurt tablet which is added with sericin antifreeze peptide and rich in Lactobacillus bulgaricus and Bifidobacterium bifidum and a preparation method thereof. Background technique [0002] Probiotics refer to single or well-defined mixed microorganisms that have beneficial physiological effects on the host by regulating the host's mucosal and systemic immune functions and improving the balance of intestinal nutrition and flora, thereby improving the health level and state of the host. In recent years, probiotics, as an important health-care functional factor, have been widely used in the development of products such as traditional dairy products, functional foods, dietary supplements, pharmaceutical biological agents, and feed. At present, the probiotic strains approved by the Ministry of Health of my country that can be used in health food m...
