An active peptide from bovine spleen for promoting digestion and absorption of children and a preparation method thereof

Abstract

This invention provides an active peptide derived from bovine spleen that promotes digestion and absorption in children, along with its preparation method, belonging to the field of active peptide preparation technology. This method effectively removes impurities, precisely controls the degree of enzymatic hydrolysis, protects the active peptide's active structure, and improves its bioavailability through steps such as hemoglobin-targeted removal, collagen dissociation and enzymatic hydrolysis, quantum dot-labeled enzymatic hydrolysis control, low-temperature two-stage inactivation, biomimetic mineralization purification, and magnetic separation and acid decomposition release. The resulting active peptide significantly improves children's digestive function and promotes the absorption of minerals such as iron and calcium, meeting the dual needs of improved digestive function and nutritional fortification in children. Furthermore, this method utilizes liquid CO2 subcritical drying technology to produce porous active peptide powder, further improving its solubility and stability. The active peptide of this invention exhibits high purity, stable activity, and good safety, possessing significant application value.
