Description

Lactic acid bacteria freeze-dried powder containing acetaldehyde dehydrogenase and preparation method and application thereof
Technical Field
The invention relates to the technical field of probiotics, in particular to lactic acid bacteria freeze-dried powder containing acetaldehyde dehydrogenase, and a preparation method and application thereof.
Background
The number of happy alcohol users in China is numerous, about 60-75% of adult men often drink alcohol, and the proportion of diseases induced by excessive drinking is increased year by year. Excessive drinking can cause liver injury and corresponding liver diseases, and can cause other diseases, especially physiological dysfunction and death of human body. Alcoholic liver injury caused by excessive drinking has become one of the most important factors for liver diseases, and at the same time, excessive drinking causes hypertension, malignant diseases such as gastric cancer, and metabolic disorders of substances such as proteins. The most common poison causing liver damage is alcohol, and liver damage caused by excessive drinking has become a worldwide medical problem. Therefore, the need for sobering up, dispelling the effects of alcohol and reducing the damages of drinking to human gastrointestinal and liver organs is urgent, and the development of effective anti-alcohol drugs has important significance and broad market prospect.
In vivo degradation of alcohol is mainly responsible for oxidation of ethanol to acetaldehyde by alcohol dehydrogenase in the liver, and the generated acetaldehyde is further converted into harmless acetic acid as a substrate under the catalysis of acetaldehyde dehydrogenase. Acetaldehyde toxicity is higher than ethanol and is the main cause of hangover. The acetaldehyde dehydrogenase is properly supplemented by oral administration, so that the metabolism of alcohol in intestinal tracts can be accelerated, and the metabolism pressure of livers can be reduced, thereby relieving uncomfortable reactions caused by alcohol and slowing down chemical liver injury.
After excessive drinking, the metabolism of the organism can be accelerated, the alcohol decomposition can be accelerated and the damage of the alcohol to the organism can be weakened by taking a large amount of small molecules such as amino acid, vitamin and the like. In addition, the energy can be rapidly supplemented by supplementing carbohydrates such as glucose and lactose, and the ethanol in the intestinal tract can be effectively neutralized by supplementing short-chain fatty acids such as lactic acid and acetic acid, so that the method has a certain effect of relieving uncomfortable symptoms.
The anti-alcohol products in the current market are mainly chemical medicines and traditional Chinese medicine preparations. The chemical for dispelling the effects of alcohol is mainly composed of stimulants, vitamins, amino acids and the like, and can quickly play a role in dispelling the effects of alcohol, but most chemical anti-alcohol mechanisms can only promote alcohol decomposition, so that the chemical has a temporary relieving effect, is difficult to play a role in protecting liver and has a large toxic and side effect. The traditional Chinese medicine preparation for dispelling the effects of alcohol has complex raw material components and complex preparation process, and is difficult to effectively improve various symptoms after being drunk to achieve the effects of dispelling the effects of alcohol rapidly and taking the principal and subordinate symptoms into consideration.
In addition, experiments prove that the occurrence, development and prognosis of enterogenic endotoxemia (intestinal endotoxemia, IETM) and alcoholic liver injury are closely related. The normal intestinal barrier has the barrier function of preventing macromolecular toxic substances such as endotoxin from entering the blood. Ethanol is taken into the intestinal tract, which causes damage to the intestinal mucosa and disturbance of the intestinal flora, and generates a large amount of endotoxin, and if the structure and function of the cell-cell tight junction occludin protein are changed, the intestinal epithelial cell permeability is increased, so that bacterial translocation and endotoxemia occur. Endotoxins cause hepatic cell steatosis, and liver injury can aggravate intestinal microecological disorders and endotoxemia, thereby forming a vicious circle.
At present, the main principle of the anti-alcohol effect through exogenous supplementation of active probiotics is that excessive drinking causes intestinal microecological imbalance to generate a large amount of endotoxin, and the liver is directly or indirectly damaged; the balance of intestinal flora is regulated by supplementing probiotics, which is helpful for reducing the generation and absorption of enterogenic endotoxin, thereby maintaining liver health, but the anti-alcoholic effect of the method is still poor.
