Problems solved by technology

[0003] Milk protein is an important source of protein needed by the human body. It contains the essential amino acids needed by the human body and is rich in nutrition. It is currently an important source of protein in foods and medicines such as formula foods for special medical purposes, infant formula foods, health foods, and enteral nutrition preparations. However, under the process conditions such as heat and shear, the properties of milk protein are unstable, and it is easy to precipitate and gel, which will have a negative impact on the taste, shelf life, reconstitution and other properties of the food, which makes milk The application of protein in food has been limited

Abstract

The invention relates to a stable lactoprotein liquid system and application thereof. The liquid system contains lactoprotein, Ca<2+>, Mg<2+> and citrate ions, wherein the mass fraction of milk protein is 0.01-20%, the difference value between the total molar concentration of the Ca<2+> and the Mg<2+> and the molar concentration of the citrate ions is less than or equal to 10mmol / L, and the pH ofthe liquid system is 7.0-10.0; the lactoprotein in the liquid system provided by the invention is high in stability, and can avoid precipitation and coagulation of the lactoprotein under the technological conditions of heating, shearing and the like, so that the application range of the lactoprotein is expanded; furthermore, the mouthfeel and the brewing property of the prepared product are improved.

Description

technical field [0001] The invention relates to the field of food and medicine processing, in particular to a stable milk protein liquid system and its application. Background technique [0002] Milk protein in emulsion includes whey protein, casein, caseinate, concentrated milk protein and some special protein mixtures for specific purposes. Protein structure, charged groups, and charge distribution will all vary with different protein types. Casein, for example, is a random linear, loose structure, while whey protein is a compact spherical structure. [0003] Milk protein is an important source of protein needed by the human body. It contains the essential amino acids needed by the human body and is rich in nutrition. It is currently an important source of protein in foods and medicines such as formula foods for special medical purposes, infant formula foods, health foods, and enteral nutrition preparations. However, under the process conditions such as heat and shear, t...
