Abstract

The invention relates to an oyster polypeptide nutrition supplement food for children and a preparation method thereof. The method comprises the following steps: deodorizing, debittering and decoloring enzymolysis polypeptide fluid which is prepared by controlled enzymatic hydrolysis of oyster meat; carrying out suction filtering, concentrating and drying to obtain oyster peptide powder; culturing and centrifuging probiotics suitable for children to obtain bacterial paste; lyophilizing with cryoprotectant to obtain probiotics lyophilized bacterial powder; preparing probiotic microcapsules by the probiotics lyophilized bacterial powder and a wall material; forming prebiotics by selecting fructo-oligosaccharide and isomaltose hypgather; weighing the following components in percentage by weight: 40 to 60 percent of oyster peptide powder, 20 to 30 percent of the probiotic microcapsules and 10 to 40 percent of prebiotics; and uniformly stirring, packaging in bags to obtain the oyster polypeptide nutrition supplement food. The oyster polypeptide nutrition supplement food quickly increases the number of beneficial bacteria in intestinal canals of children while providing rich nutrition to children, so that the environment in a body is improved, and the nutrition absorption capability is improved. The preparation method has the advantages of reasonable process, simple manufacture and strong operability.

Description

technical field [0001] The invention relates to a peptide-containing food composition or its processing, in particular to an oyster polypeptide nutritional supplement food for children and a preparation method thereof. Background technique [0002] Children are a special group, and their particularity is reflected in the fact that they are in the stage of body and brain development. Therefore, sufficient and well-balanced nutrition is the material basis for children's growth and development. Insufficient nutrition will first lead to no weight gain or even weight loss, and will eventually affect the growth of height and the functions of other body systems, such as immune function and endocrine function. , neuromodulatory functions, etc. Because children are in the development period, their intestinal and gastric functions are not yet perfect, and the children's nutritional food sold on the market is composed of cereals or fruits and vegetables mixed with fish and meat, which...
