Abstract

The invention relates to fish scale protein peptide calcium chelate, a microcapsule calcium supplement of the chelate and preparation methods thereof. In the invention, calcium chloride and the enzymatic hydrolysate of fish scale protein are chelated, thus improving the solubility of the calcium salt under a subalkaline condition in the intestinal tracts and improving the absorption utilization ratio of calcium, and the preparation process is safe and pollution-free. In the invention, an appropriate wall material is also adopted for microencapsulating the fish scale protein peptide calcium chelate to prepare the microcapsule calcium supplement of the fish scale protein peptide calcium chelate; the calcium supplement can cover up the off flavor of the calcium salt and can gradually release Ca<2+> under the subalkaline condition in the intestinal tracts, and the biological absorption utilization ratio of the Ca<2+> is high without toxic side effect; and due to the fish scale protein peptide, the fish scale protein peptide calcium chelate not only can prevent and treat osteoporosis, but also has the physiological functions of resisting oxidation, adjusting immunity, reducing blood pressure and the like.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to a fish scale protein peptide calcium chelate, its microcapsules, their preparation method and biological application. Background technique [0002] Calcium is one of the essential mineral elements for the human body. Calcium is an important component of bones and teeth. Calcium participates in the stress process of nerve and muscle tissue, and also participates in blood coagulation, regulation of enzyme activity, hormone secretion, and maintenance of acid-base balance of body fluids. And regulate the normal physiological function of cells. However, ingredients such as phosphate and oxalic acid in food interfere with the absorption of calcium, and the absorption and utilization rates of inorganic calcium supplement products and organic calcium supplement products are also low. Therefore, finding a safe and effective calcium supplement product is of great significance to h...
