PRESERVED EGG PROTEIN SOURCE ANTI-INFLAMMATORY PEPTIDE BEVERAGE AND PREPARATION METHOD THEREOF
Technical Field
The present invention belongs to the field of food processing, relates to an anti-inflammatory peptide beverage prepared by enzyme methods, and particularly relates to a preserved egg protein source anti-inflammatory peptide beverage and a preparation method thereof.
Background
If organisms are exposed in reactive oxygen and free radicals of different sources for long time, excessive reactive oxygen and free radicals will cause redox imbalance in cells, thereby causing oxidative stress and further inducing in-vivo inflammations. Meanwhile, inflammatory cells are activated to secrete proinflammatory cytokines, which may cause damage of tissues and denaturation of proteins, thereby influencing health of the body. Researches show that, many diseases are caused by inflammations, such as inflammatory bowel disease, coronary atherosclerosis and Alzheimer's disease. Therefore, searching an exogenous anti-inflammatory agent is an important means of treating inflammation-mediated diseases. Anti-inflammatory peptides are a category of bioactive peptides beneficial to the organisms, and regulate inflammatory response of the organisms by comprehensively regulating secretion of cytokines, synthesis or release of inflammation mediators and inflammatory signaling pathways. Adequate intake of substances having anti-inflammatory activity may decrease content of in-vivo proinflammatory factors and prevent the inflammations. Many common medicines for treating the inflammations exist, such as penicillin, cephalosporin and glucocorticoids, but have certain side effects such as dependence, drug resistance
Description
and allergies. A natural anti-inflammatory agent is relatively safe, and has an effect in treatment or adjuvant therapy of the inflammations. A Chinese medical book Yilin Cuanyao Tanyuan records that, preserved eggs have effects of "clearing away lung heat, dispelling the effects of alcohol, relieving internal heat of the large intestine and treating diarrhea and can dissipate and astringe". In life, the preserved egg is always taken as an excellent cold food of "reducing internal heat". By virtue of modern experimental methods and technological means, it is first proved that preserved egg enzymolysis polypeptides have obvious anti-inflammatory activity. Beverage is a well-known and generally accepted liquid food that is rich in taste, convenient to eat and easy to preserve. The beverages are roughly classified into carbonate beverages, fruit and vegetable juice beverages, functional beverages and the like. Most of the raw materials of functional healthy beverages include extracts of natural plants, Chinese herbal medicines, fungus extracts, mineral substances, marine product extracts and functional additives. A method for taking anti-inflammatory peptides obtained by performing enzymolysis by taking preserved eggs as a protein source as raw materials of the beverages is not involved in China and abroad. At present, the research on bioactive peptides prepared from enzymolysis proteins mainly focuses on antioxidant peptides. CN105254714A discloses a method for preparing an antioxidant peptide by enzymolysis of milk casein. In the method, separation, desalination and concentration are performed by virtue of ion exchange column chromatography. CN105820229A discloses a method for preparing an antioxidant peptide by enzymolysis of duck gizzard proteins. In the method, hydrolysis is performed by adding 0.4-0.6% of protease. CN105648005A discloses a method for preparing an antioxidant peptide by enzymolysis of sphyrna chondroprotein. In the method, ion exchange resin chromatography, gel column chromatography and purification by reversed high performance liquid
Description
chromatography are performed. However, the research on the anti-inflammatory peptides and products such as anti-inflammatory peptide beverages taking preserved egg proteins as sources are not involved.
