Abstract

The present invention provides a preparation method of Schizochytrium peptide chelated calcium with antioxidant activity, comprising the following steps: (1) ultrasonic-assisted cellulase and amylase hydrolysis; (2) compound hydrolysis of three kinds of proteases; ( 3) Separation by ultrafiltration; (4) Ultrasound-assisted chelation of peptides and calcium ions to prepare Schizochytrium peptide chelated calcium with antioxidant activity. The preparation method of the Schizochytrium peptide chelated calcium with antioxidant activity is simple in process and can be applied in large-scale actual production. The remaining algae residue after oil extraction from Schizochytrium is used as raw material, which improves the resource utilization of Schizochytrium rate; the schizochytrid peptide chelated calcium prepared by the method of the present invention has dual biological activities of anti-oxidation and promotion of calcium ion absorption.

Description

technical field [0001] The invention belongs to the technical field of functional peptide chelated calcium ions, and specifically relates to a preparation method of chelated calcium with antioxidative activity of schizochytrium peptide, and also relates to the preparation method of schizochytrium peptide with antioxidative activity Chelated Calcium. Background technique [0002] Peptide-mineral ion chelate is a metal-organic compound, which is prepared by chelation reaction between mineral ions and peptides. It can improve the bioavailability of metal ions by virtue of the absorption mechanism of peptides in the body. Physiological and biochemical properties that inorganic metal ions do not have. At present, the chelate prepared by chelating essential trace elements and peptides has become a new type of mineral ion supplement, and has attracted more and more attention. [0003] At the same time, because peptides with specific molecular weight and amino acid sequence also h...
