Problems solved by technology

The disadvantage of the above method is that only a single enzymatic hydrolysis of the fish skin is carried out so that the collagen polypeptides in the fish skin can be utilized
[0004] From the above search results, it can be seen that there is no report on the composite fish skin bone protein peptide chelated calcium powder developed by synchronously using collagen peptides in fish skin combined with fish bones

Abstract

The invention discloses complex chelated fish skin bone protein polypeptide calcium powder, belonging to the field of food processing methods. A preparation method of the complex chelated fish skin bone protein polypeptide calcium powder mainly comprises the steps: respectively digesting and pulping fish bones and fish skins, then mixing the obtained fish bone paste and fish skin pulp to obtain fish skin and bone paste; then adding water and compound protease for conducting enzymatic hydrolysis, and centrifuging the enzymatic hydrolysate to respectively obtain supernate and precipitate; and conducting airflow grinding on the precipitate to obtain ultramicro fish bone powder, conducting acidifying processing on the ultramicro fish bone powder in a lactic acid solution, then mixing fish bone calcium liquid with the supernate in a bioreactor, and conducting a chelating reaction to obtain the complex chelated fish skin bone protein polypeptide calcium powder. The complex chelated fish skin bone protein polypeptide calcium powder has a better antioxidant function; secondarily, the chelated calcium powder is good in solubility, and the biological calcium absorption rate is high; the chelated calcium powder provides collagen protein polypeptide which has the effects of enhancing the metabolism of cortical cells and preventing aging. The preparation method is simple and low in cost.

Description

technical field [0001] The invention belongs to the technical field of functional food processing, and in particular relates to a composite fish skin bone protein polypeptide chelated calcium powder and a preparation method of the composite fish skin bone protein polypeptide chelated calcium powder. Background technique [0002] Fish bones are rich in calcium, similar to the calcium composition of human bones, and are an excellent natural calcium source; fish bones also contain all the amino acids that make up human protein; in addition, the mineral content in fish bones is significantly higher than other foods , The ratio of calcium to phosphorus in bones is approximately 2:1, which is the best ratio for the body to absorb calcium and phosphorus. At present, there have been some reports on the processing and utilization of fish bones and product development. For example, the patent "A Fish Bone Bioactive Polypeptide Calcium Powder and Preparation Method" (publication number...
