The brewing method of bilateral fermentation of yellow rice wine with koji is obviously different from other brewing wines in the world. The invention of Qu was a great contribution of working people in ancient China, which laid the foundation of alcohol industry and had a far-reaching impact on modern fermentation industry and enzyme preparation industry.
Yellow rice wine is a traditional health care product, and its health care function has been highly praised by experts. Compendium of Materia Medica contains 69 kinds of medicinal liquor, all of which are made of yellow wine. Even with the development of science today, many Chinese medicines are brewed with yellow wine to improve their efficacy.
The research results of functional components such as phenols, oligosaccharides, peptides and functional amino acids in yellow rice wine show that the unique brewing method gives yellow rice wine a unique health care function.
1, rich in phenols.
Phenols have antioxidant function, which can not only inhibit the oxidation of low density lipoprotein, but also help prevent coronary heart disease and atherosclerosis, and also have the effects of scavenging free radicals, anticancer, anti-aging, anti-inflammatory diseases and platelet aggregation. The content of phenolic compounds in ancient Yue Longshan Shaoxing yellow rice wine (stored for many years) is high (see table 1). These phenolic compounds come from the transformation of raw materials (rice, wheat) and microorganisms (Aspergillus oryzae, yeast), especially because the fermentation cycle is about 100 days, and a large number of phenolic compounds in wheat skin are dissolved in wine. However, during storage,
2. High content of functional oligosaccharides
Functional oligosaccharides are not easily digested by human body, and produce little or no heat after ingestion, but can be utilized by beneficial microorganism Bifidobacterium in intestinal tract, which can promote the proliferation of Bifidobacterium, improve intestinal microecological environment, promote the synthesis of B vitamins and the absorption of minerals such as calcium, magnesium and iron, improve immunity and disease resistance, decompose intestinal endotoxin and carcinogens, prevent various chronic diseases and cancers, and reduce serum cholesterol and blood lipid levels.
3. It is rich in the important inhibitory neurotransmitter γ -aminobutyric acid.
γ -aminobutyric acid (GABA) is an important inhibitory neurotransmitter, which participates in a variety of metabolic activities, and has physiological activities such as lowering blood pressure, improving brain function, enhancing long-term memory, anti-anxiety, reducing weight efficiently, and improving liver and kidney functions. GABA can act on the motor center of spinal cord blood vessels, effectively promote vasodilation and achieve the effect of lowering blood pressure. According to reports, the active ingredient of traditional Chinese medicine such as Astragalus is GABA. GABA can also improve the activity of glucose phosphatase, make brain cells active, promote the metabolism of brain tissue, restore the function of brain cells and improve nerve function. In medicine, GABA has a good effect on hemiplegia and memory disorder caused by cerebrovascular disorder, and is also used as a drug for uremia and sleep disorder. In addition, Japanese researchers conducted medical experiments with foods rich in GABA, and the results showed that they had obvious improvement effects on Parkinson's disease and Alzheimer's disease.
4. Unparalleled bioactive peptides
Recent studies show that oligopeptides composed of several amino acids have better absorption characteristics than amino acids, and many peptides have physiological functions that protein or its constituent amino acids do not have, such as promoting calcium absorption, lowering blood pressure, lowering cholesterol, calming the nerves, regulating immunity, resisting oxidation, scavenging free radicals, and resisting cancer.
