Abstract

The invention discloses an amino-acid-rich health-care marine protein product for infants and a preparation method of the amino-acid-rich health-care marine protein product. Various marine protein raw materials are combined scientifically, the amino-acid-rich health-care marine protein product is obtained with microbial fermentation and a multi-step continuous enzymolysis process, novel marine economy is cultured on the basis of realization of high-value development and utilization of marine protein, and the health care requirements for growth of the infants are met. The amino-acid-rich health-care marine protein product obtained with adoption of ultrasonic-assisted enzymolysis, an aerobic fermentation process and secondary enzymolysis is crystal white in color, powdery and free of impurities or bitterness, the total protein content is higher than or equal to 98%, and the content of peptides with the molecular weights lower than 1,000 daltons in the total protein is higher than or equal to 90%. The preparation method has the advantages that the production cycle is short, the cost is low, no toxic or harmful substance is produced, and the health-care marine protein product is high in safety, good in functional activity, balanced in nutrition, digestible and absorbable, has remarkable effects of promoting growth, improving immunity of the bodies of the infants, supplementing calcium and the like and has broad market application and popularization prospect.

Description

technical field [0001] The invention relates to a marine protein health product rich in amino acids for infants and a preparation method thereof, which belongs to the field of health food processing. Background technique [0002] Protein is the main substance that constitutes the tissues and organs of the human body. It plays a very important role in the life activities of the human body. It is necessary to maintain and repair the body and cell growth. It not only affects the growth of body tissues, but also participates in the production of hormones, immune Therefore, protein is one of the important nutrients to ensure good health. [0003] The 21st century is the ocean century, the century of sustainable development of marine economy. There are about 400,000 species of organisms living in the ocean, which accounts for 71% of the total area of ​​the earth, accounting for 80% of the total number of species on the earth. It is estimated that the ocean produces approximately...
