Problems solved by technology

Among them, the absorption rate of calcium, iron and zinc in inorganic metal salts and organic acid-metal salts is less than 40%.
Clinical studies have shown that in the absence of three elements at the same time, supplementing one of them alone cannot achieve improvement

Abstract

The invention aims at providing an euphausia superba peptide replenisher containing calcium, iron and zinc. The euphausia superba peptide replenisher containing calcium, iron and zinc is obtained by combining calcium, iron and zinc metal elements with euphausiid peptide powder prepared by euphausia superba powder defatting, protease degradation and CaCl2 defluorination. The adopted raw materials of the euphausia superba peptide replenisher containing calcium, iron and zinc provided by the invention are abundant, easily available, and high in protein content; the preparation method has the advantages of being simple in process steps, low in equipment investment, free from environmental pollution, high in product yield and the like, and is suitable for industrialized production; the prepared euphausiid peptide-calcium, iron and zinc replenisher has the characteristics that the protein content is higher than 90%, and thus the product purity is high; the fluorine content is lower than 10 ppm, and thus the product safety is high; the molecular weight is mainly distributed between 2000-200 Da, and thus the water solubility is good; the essential amino-acid content is high, the composition of calcium, iron and zinc is reasonable, and three nutrients and essential amino-acids can be replenished simultaneously.

Description

technical field [0001] The invention belongs to the technical field of functional food, and in particular relates to an Antarctic krill peptide supplement containing calcium, iron and zinc, a preparation method and application thereof. Background technique [0002] Calcium, iron and zinc deficiency is a series of related diseases caused by the lack of calcium, iron and zinc. It has become an increasingly serious social health problem worldwide, especially for the elderly, children and pregnant women. special groups such as women. Zinc deficiency is mainly manifested as stunted growth and development, suppressed immune system function, brain damage in perinatal infants, anorexia, skin infections, and decreased reproductive capacity. Iron deficiency is mainly manifested as weakened bactericidal ability of phagocytes and decreased immunity of the body. Calcium deficiency is mainly manifested in conditions such as osteoporosis, high blood pressure, colon cancer, obesity and ki...
