Problems solved by technology

Normal fat-free cream is made by adding thickeners such as pectin, guar gum and other food additives to increase the surface viscosity and elasticity of the liquid film. Although this is in line with the regulations on food additives , but the whipping property is poor, but it is easy to cause consumers' concerns, thus affecting the application of non-fat cream in food

Abstract

The invention relates to a preparation technology of whey lactic acid bacterium fermentation liquid with an excellent whipping characteristic. The preparation technology comprises the following steps: 1) powder dissolving: dissolving whey protein powder into water to form a whey solution, 2) homogeneity, 3) sterilization. 4) cooling, 5) inoculating: inoculating lactic acid bacterium freeze-drying powder fermentation agent, 6) fermentation, 7) ripening, and 8) mixing: dissolving and heating 75wt% of white granulated sugar solution to 95 DEG C, holding for 5-10min, then cooling to the room temperature to form 75wt% of syrup, allowing a mixing mass ratio of 75%wt of syrup and the fermentation liquid to be 1:9-2:8 during mixing, and obtaining a finish product, wherein the inoculating amount of the fermentation agent is 0.01-0.1% of the weight of a laundry whey solution, and lactic acid bacterium freeze-drying powder is prepared by lactobacillus paracasei, lactobacillus acidophilus, lactobacillus helveticus and lactococcus lactis subsp lactis at a bacterial count ratio of 2:1:1:2. The whey lactic acid bacterium fermentation liquid produced by the technology is free from fat, and has the better whipping characteristic and characteristics of an active lactic acid bacterium product.

Description

technical field [0001] The invention relates to a preparation process of whey fermented liquid with excellent whipping properties, in particular to a method for increasing whipping foam retention by utilizing exopolysaccharide produced by fermentation of lactic acid bacteria without adding colloids. Background technique [0002] Whey protein is a kind of protein existing in milk whey, and it is the main component in milk whey. Its biological value can be evaluated from two aspects, namely the amino acid composition and physiological function of whey protein. Whey protein contains a complete range of essential amino acids, and its composition pattern is similar to that of the human body. It is easily digested and absorbed, and has a high bioavailability. Whey protein has various functions and comes from natural foods. It is the most economical available One of the sources of food protein. It has more obvious physical and chemical properties: gelation, whipping foaming, emuls...
