The invention discloses a
sea cucumber polypeptide
functional food and a preparation method thereof which not only remarkably improves the content of polypeptide, but also has no chemical residues; the contents of salt and
arsenic are low; the food is healthier and
safer to eat; simultaneously the food is simply operated, easily controlled, is effective and saves energies. The key technical scheme includes: selecting a compound
protease of Protamex and needing not to adjust the pH value of materials; carrying out processes of desalting and
arsenic removing on an enzymolysis liquid; more than 80 percent of the molecular weight of the product is between 100 to 6000Dalt; wherein, the small polypeptide of 100 to 2100Dalt is more than 70 percent; the product components and the content weight percentages are as follows: 50 to 60 percent of polypeptide, 5 to 10 percent of
free amino acids, 2.5 to 7.5 percent of mucoitin as well as containing the inherent
nutrition components of a plurality of minerals and vitamins of the
sea cucumber. The product has the effects of resisting knub, reducing
blood pressure, preventing cardio-cerebrovascular diseases, resisting fatigue, delaying
senescence, improving the
immunity. The food can be used as a
healthy food to eat and can also be used as a food and a
medicine additive.
