The Research of Physical and Chemical Properties of Casein Micelles in Milk and Thermal Stability Affecting Factors
Casein is the protein with the highest content and the richest nutritional components in different animal-derived milk.Casein usually exists in milk in the form of casein micelles.Casein is composed of 4 casein monomers,αs1-casein,αs2-casein,β-casein and κ-casein and mineral aggregates,suspended in solution.The physical and chemical properties and thermal stability of casein micelles determine the quality of milk and dairy products.Therefore,the composition and characteristics of casein,the characteristics of casein micelles and the factors affecting the thermal stability of casein micelles were comprehensively summarized in this paper,which can promote the understanding of casein micelles and establish a theoretical basis for the in-depth application of casein.
