A kind of polypeptide low water emulsion loaded with oil and its preparation method and application

Abstract

The present invention provides a polypeptide low-water emulsion loaded with oil and fat, and its preparation method and application, which relate to the field of food or health food. The polypeptide low-water emulsion loaded with oil and fat is made of raw materials including the following components: aqueous phase raw materials, including polypeptide, water-soluble emulsifier, sugar substance, glycerin and water; oil phase raw materials, including fat-soluble emulsifier and oil and fat. The present invention is the first to use high-concentration polypeptide as an aqueous phase filler to construct a low-water emulsion system, and uses a water-soluble emulsifier with good emulsification effect to improve the stability of the system, and combines sugar and glycerin to optimize the flavor and viscoplasticity of the emulsion, thereby obtaining a polypeptide low-water emulsion with good protective effect on oil and fat and the lipophilic active ingredients therein. The low-water emulsion system is beneficial to improving the stability of lipophilic active ingredients in oil and fat, preventing the active ingredients from oxidative deterioration and causing quality deterioration, and extending the shelf life of the product; the bad flavor of oil and fat is concealed by emulsion encapsulation, avoiding the use of chemical flavors, and improving the sensory experience of consumers.
