Description

A nutrition-enriched oatmeal food containing marine chondroitin sulfate and its preparation method
Technical Field
The invention belongs to the technical field of aquatic product processing, and particularly relates to a nutrition-enriched oatmeal food containing marine chondroitin sulfate and a preparation method thereof.
Background
Cartilaginous fishes, namely chondroiidae, are the oldest jawed vertebrates, mainly comprise sharks, stingray, ray, scomberomorus mackerel and the like, are one of the main components of a marine ecosystem, and cartilaginous fish cartilage is rich in active substances such as polypeptides, low molecular weight proteins, glycoproteins, polysaccharides and the like, and can be used as a new blood vessel generation inhibiting factor, a tumor cell inhibiting factor, an immunoregulation factor, an anti-invasion factor and the like for treating and preventing tumors.
Shark lives in the sea, has fierce sex, is quick to move, catches other fishes, has high nutritive value, has high protein content and special structure, contains mucopolysaccharide (amino polysaccharide) and other substances rich in biological activity, and Japanese scholars introduce vivid examples related to disease treatment and prevention in more detail in the book of shark chondroitin magic drug effect. Shark chondroitin sulphate, found in v.b. krylov et al, has anti-inflammatory activity and also exhibits some anticoagulant properties. Shark chondroitin sulfate has unique functions relative to class A chondroitin (pig, cattle, chicken, etc.), has anti-angiogenesis and anti-cancer activities to human and animals, and is widely applied to dietary supplements; furthermore, shark cartilage has therapeutic effects on osteoarthritis, rheumatoid arthritis, progressive systemic sclerosis and neurovascular glaucoma.
The ossein peptide is a potential calcium source, can promote the human body to absorb calcium in the diet, improves the bioavailability of the calcium for the human body, enhances the bone density and prevents osteoporosis. The shark has high content of organic calcium, has absorption rate far higher than that of inorganic calcium, and is a good calcium supplement source for middle-aged and elderly people with high osteoporosis incidence.
Chondroitin sulfate and collagen derived from marine aquatic animals are obviously superior to chondroitin sulfate and collagen derived from terrestrial animals in many aspects, and have the advantages of strong safety, low allergy, low antigenicity and the like. Because the safety of many high-risk viruses and pathogenic microorganisms such as mad cow disease, oral plague and the like is questioned, the application of biological products from animals is strictly limited, and chondroitin sulfate and collagen products from deep sea cartilaginous fish have wider application prospect.
Cartilaginous fish is mainly processed into frozen products, but the skull and the fin bones which account for nearly 15 percent of the weight of adult fish are often discarded as waste in the processing process of cartilaginous fish, and cannot be fully utilized. The technology exploits downstream products for comprehensive utilization of cartilaginous fish processing, changes waste into valuable, avoids environmental pollution and resource waste, and greatly improves the added value of products. Not only can realize the comprehensive utilization of cartilage resources, but also can provide new resources for developing calcium supplement products. The utilization value of the cartilaginous fish body is maximized, and the economic value of the cartilaginous fish raw material is comprehensively improved.
