[0035] A method for preparing selenium-enriched black peanut double-protein flavor fermented milk at room temperature, the method comprising the following steps:

[0036] (1) After soaking black peanuts, refining and sieving, black peanut pulp is obtained;

[0037] (2) After preheating the raw milk, add the black peanut pulp obtained in step (1), whey protein powder, sweetener, and stabilizer for mixing, homogenize, sterilize, and cool to obtain a mixture liquid;

[0038] (3) adding a starter to the mixed material liquid obtained in step (2), fermenting to obtain a mixed fermented liquid;

[0039] (4) cooling, sterilizing and filling the mixed fermented liquid obtained in step (3), to obtain final product;

[0040] Based on 100% of the total mass of the mixed material liquid, the added amount of black peanut pulp is 13-20%, the added amount of whey protein powder is 0.3-1.0%, the added amount of sweet substances is 5-8%, and the stabilizer The addition amount of the powder i...

Abstract

The invention discloses normal-temperature selenium-rich black peanut double protein-flavor fermented milk and a preparation method thereof. The method comprises the following steps: (1) soaking blackpeanuts, carrying out pulping and sieving, so as to obtain black peanut pulp; (2) preheating the raw materials, adding the black peanut pulp, whey protein powder, sweet substances and a stabilizer, mixing, carrying out homogenization and sterilization, and cooling, so as to obtain mixed material liquid; (3) adding a fermenting agent into the mixed material liquid for fermenting, so as to obtain mixed fermented liquid; and (4) cooling the mixed fermented liquid, and carrying out sterilization and encapsulation, so as to obtain the fermented milk. By utilizing the black peanuts with a relatively high addition amount during the fermentation, the prepared normal-temperature selenium-rich black peanut double protein-flavor fermented milk has good stability and excellent taste and flavor and has a stable tissue state in a guarantee period, and whey is not separated out.

Description

technical field [0001] The invention relates to the field of dairy products, in particular to a normal-temperature selenium-enriched black peanut double-protein flavored fermented milk and a preparation method thereof. Background technique [0002] Black peanut is a new variety of peanut that has attracted much attention recently, also known as selenium-enriched peanut. Its appearance is the same as that of ordinary peanuts, but the inner skin is black, and the kernel is still white. Its quality advantage is mainly reflected in the nutritional components. Black peanuts are famous for their rich selenium content of 0.083mg / g, which is 101% higher than that of ordinary peanuts. A large number of animal models and human experiments have proved that selenium has chemopreventive function. Selenium deficiency is related to various tumors. Selenium can induce apoptosis and produce anticancer effects. Black peanuts contain 30.68% crude protein, which is an excellent source of ve...
