The invention relates to a preparation method of a sterilization type compound
protein enzymolysed and fermented dairy product, belonging to the technical field of dairy products. The sterilization type compound
protein enzymolysed and fermented dairy product contains milk, peanuts, white granulated
sugar, strains, a stabilizing agent, an
enzyme preparation,
polydextrose and water. The preparation method is characterized by comprising the following steps: screening a milk source, treating the peanuts, mixing
powder, dissolving
sugar and mixing, homogenizing, sterilizing, inoculating, fermenting, breaking
emulsion, refrigerating, carrying out
pasteurization and sterilely filling. According to the preparation method,
protein components and dietary fibers in the peanuts can be kept to the greatest extent; and meanwhile, an
enzyme preparation
hydrolysis process has the effects of reducing the foreign taste of the peanuts, improving the taste of the products and enhancing the absorption of a
human body. The dietary fibers are good for maintaining intestinal health. The content of animal and
plant compound proteins of the product reaches up to 2.3%, the nutritive value is high and the animal and
plant compound proteins are balanced and complementary. The product is particularly packaged by
tetra prisma or
brick type compound paper which has good barrier property so that the product in a
shelf life is not polluted by external
bacteria; and the
package facilitates drinking and carrying, and the
shelf life of the product at a
room temperature can reach 6 months.
