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.

Preparation of sponge-like porous materials of silk protein is carried out by converting its conformation with denaturant at low temperature to have frozen phase separation to obtain the product. Its parameters can be regulated by controlling concentration of the silk protein, amount of denaturant or its characteristics, freezing time or post-treatment in porosity, pore size, and mechanical performance. Neither cross-linker nor pore-generating agent nor surfactant nor organic solvent with strong toxicity is used. It is produced in a simple process, and has a uniform texture, high porosity up to 98%, good toughness and elasticity and reliability, water absorbing rate up to 5000%, elastic recovery rate 100% and press deformation >90%.
