Abstract

The invention provides a preparation method of collagen polypeptide chelated calcium. The preparation method comprises the following steps of: performing enzymolysis on animal skin gelatin by a two-step enzymolysis method to prepare micromolecule collagen polypeptide abundant in oxyproline; and performing chelation reaction on the micromolecule collagen polypeptide and food-grade soluble ionized calcium to prepare the collagen polypeptide chelated calcium. The process for preparing the collagen polypeptide chelated calcium is simple; the chelation rate reaches 77 milligrams of ionized calciumper gram of collagen polypeptide; the prepared collagen polypeptide chelated calcium has high water solubility, is absorbed by a human body easily, supplements the calcium element required by the human body, also supplements the oxyproline for promoting calcium absorption, and is a good calcium supplement product.

Description

technical field [0001] The invention relates to a preparation method of collagen polypeptide chelated calcium, which belongs to the technical field of synthesis of food additives and calcium supplements. Background technique [0002] Calcium is one of the most abundant mineral elements in the human body. Among all the elements that make up the human body, it ranks fifth after carbon, hydrogen, oxygen, and nitrogen. Calcium is an important component of bones and teeth, an element necessary for animal life activities, and the source of animal body metabolism. Animal life activities such as transmission of nerve substances, heartbeat, muscle contraction, etc. are all using and consuming calcium. . Due to many reasons such as eating habits, living habits, age levels, etc., calcium is still one of the most deficient nutrients in the Chinese population. With the improvement of people's living standards and the enhancement of health awareness, people are increasingly aware of th...
