Description

A Functional Old Goose Braising with a special flavor and preparation method thereof
TECHNICAL FIELD
The invention relates to an old goose braising in particular to a functional old goose braising with a special flavor and the preparation method thereof.
BACKGROUND
Soybean is rich in isoflavones. Modern medical research studies shows that flavonoids have many biological activities, such as anti-inflammation, anti-tumor, anti-virus, etc. And they have important application value in the aspects of anti-tumor treatment and anti-aging.
Flavonoids are widely distributed in nature, mainly in plants, and mostly in the form of flavone glycosides. Flavone glycosides, as a kind of macromolecular substances, are difficult to penetrate into intestinal epithelial cells, so they are difficult to be absorbed by human body. And their bioavailability is low, which reduces their practical application value.
Flavonoid aglycones have strong membrane permeability, easily penetrate intestinal mucosal cells, and are easier to be absorbed by human body compared with flavone glycosides. Flavone glycosides can be converted into corresponding flavonoid aglycones by technical methods, which can greatly improve their bioavailability. However, the traditional chemical conversion method has low environmental friendliness, which is not conducive to large-scale industrial application. Therefore, in recent years, researchers aim to explore the novel transformation methods of flavone glycosides. Biotransformation of flavonoids by microorganisms is a very safe, efficient, and low-cost method.
China is the largest goose-raising country in the world, and it is also the country with the largest consumption of goose products around the world. Goose meat is a kind of food with high protein and low fat. According to analysis, its protein content is 22.3%, while pork is only 14.8%, which is much higher than that of beef and mutton; Lysine content is 30% higher than that of chicken; The fat content of goose meat is low, only about 11%, and most of them are unsaturated fatty acids which are beneficial to health (the fat content of lean pigs is about 28.8%, and that of lean mutton is about 13%). What's more, the cholesterol content is very low, so it has a good health care function. However, goose meat processing products in China are relatively simple, mainly including sauced, marinated, roasted and baked products. Although the old goose braising has been industrialized in production, its variety and flavor are relatively simple. At present, there is no research report on the development of functional old goose braising with special flavor by using Mucor and Lactic acid bacteria compound fermentation.
SUMMARY

Compared with the existing technology, the invention has the advantages that: the invention discloses a method for preparing the special flavor old goose braising with antioxidant and immunomodulatory functions by fermentation method for the first time. Because soybean flour, milk powder, exogenous protease, and multi-strain fermentation are added in the preparation method, the content of free amino acids and polypeptides in the product is improved 50-60%, and the product has rich flavor substances and good taste.
The adopted soybean flour is rich in flavonoids, and lactose in milk powder can promote the growth of Lactic acid bacteria. In addition, the fat in milk powder has a good fragrance, 5 which can mask the unpleasant smell of goose meat.
In addition, because Lactic acid bacteria and Mucor are used as the main fermentation strains, the B -glucosidase secreted by them can decompose flavone glycosides which are not easily absorbed in soybean flour and cabbage into flavonoid aglycones which are easily absorbed by the body, thus improving the biological titer of flavonoids in soybean flour and cabbage.
In addition, proteases, lipases and amylases secreted by Lactic acid bacteria and Mucor decompose protein into soluble small molecular peptides and amino acids, fat into glycerol and fatty acids, starch into glucose, and produce aromatic substances or protein decomposition products with delicate flavour, thus improving the digestion and absorption performance and nutritional value of nutrients.
Flavonoids, peptides and laminarin produced by proteolysis of soybean protein and milk protein have antioxidant and immunomodulatory functions. Therefore, the developed old goose braising has antioxidant and immunomodulatory functions, and its total antioxidant capacity and hydroxyl free radicals inhibition capacity are increased by 95.68% and 131.17% respectively compared with ordinary old goose braising
