Problems solved by technology

[0007] Although vinegar can alleviate the anesthesia effect of excessive alcohol, because the above-mentioned esterification reaction is carried out in the human body, it will be interfered by many factors, and the reaction speed is very slow, hydrochloric acid is needed as a catalyst, and hydrochloric acid in the body mainly Concentrated in the stomach and the amount is very limited, the speed of the esterification reaction is far lower than the digestion speed of the liver and kidney, the burden on the liver has not been relieved too much, so the effect is not ideal

Abstract

The invention discloses a preparation method and applications of freeze-dried powder of acetic acid bacteria. The preparation method comprises following steps of: 1) inoculating the acetic acid bacteria into a liquid culture medium and culturing at 28-30 DEG C for 10-30 h to obtain a primary strain; 2) inoculating the primary strain into a fermentation culture medium, culturing at 28-33 DEG C for 10-30 h, and adding an aqueous sodium hydroxide solution having a concentration of 5-25 wt% during the fermentation process to obtain a fermentation liquid mixture; 3) filtering the fermentation liquid mixture or centrifuging and separating to obtain bacterial sludge; 4) uniformly mixing the bacterial sludge and a bacterial sludge protective agent to obtain a bacterial suspension; and 5) freeze-drying the bacterial suspension to obtain the freeze-dried powder of the acetic acid bacteria. After the freeze-dried powder of the acetic acid bacteria is mixed with various additives, alcoholism-relieving tablets and alcoholism-relieving beverages, which have good alcoholism-relieving effects, can be obtained through different processes. The preparation method is simple and the freeze-dried powder of the acetic acid bacteria is high in bacterium content and long in storage time.

Description

technical field [0001] The invention relates to the field of biological health food, in particular to a preparation method and application of acetic acid bacteria freeze-dried bacteria powder. Background technique [0002] With the continuous progress and development of society, alcohol is playing an increasingly important role in people's social life, and alcohol culture is also popular all over the world, but excessive drinking can cause serious damage to the liver, because excessive drinking means that excessive alcohol exceeds Alcohol will cause direct or indirect damage to liver cells if the metabolism and detoxification capabilities of the human liver are impaired. Each of the three metabolic steps of alcohol in liver cells has potential toxicity to cells, such as direct damage to liver cells, stimulation of fat synthesis, hypoxia, and production of acetaldehyde, which induces the activities of various enzymes and disrupts liver metabolism, causing a series of clinical...
