However, the herbs or prescriptions are empirical medicine, have no definite functional components, have low curative effect, slow effect, lack evaluation basis and take time for decoction, and are not easy to be accepted by drinkers due to bad smell and taste.
In recent years, enzymes are a functional food. The definition of the edible plant enzyme in the ' enzyme product classification guide "(QB/T5324) standard implemented in 2016 (9 months) of China is ' an enzyme product which is prepared by taking plants which can be used for food processing as main raw materials, adding or not adding auxiliary materials and carrying out microbial fermentation on the main raw materials and contains specific bioactive components and can be eaten by human beings '. The patent application CN202010165035 discloses a functional fermented beverage for relieving alcoholism and protecting liver and a preparation method thereof, wherein the fermented beverage comprises raw materials of 510g of red dates, 1015g of kudzuvine root powder and the balance of water; the probiotics used for fermentation of the functional fermented beverage for dispelling the effects of alcohol and protecting the liver is one of lactobacillus plantarum or pediococcus acidilactici. Although the application belongs to the enzyme category, the traditional Chinese medicine components of kudzu root and red date are used as raw materials, so that the curative effect is limited, the functional components are not clear enough, and the key evaluation basis for the effect is lacked.
Angelica keiskei Koidzumi (Angelica keiskei Koidzumi) is a perennial herbaceous plant originating in the same place of Japan, and approved as a new food material resource by the examination of the national Committee for health and wellness in 2019. The angelica keiskei koidzumi is rich in nutrition, is rich in flavonoid active substances, and has good health-care effects of resisting oxidation, resisting tumors and the like. However, the existing angelica keiskei koidzumi tea and angelica keiskei koidzumi powder are low in total flavone content and insufficient in oxidation resistance, and the effect of preventing and repairing liver diseases caused by alcoholic liver injury is still achieved, so that the effect of the angelica keiskei koidzumi product on protecting the liver is still greatly challenged.

Figure BDA0003996757220000151
The cellular senescence process can be truncated or delayed by antioxidant and anti-free radical pathways, depending on the cellular current senescence mechanism. Therefore, the higher the total flavone value and the higher the SOD value in the angelica keiskei ferment, the stronger the anti-cell aging effect of the product. As can be seen from Table 1: by the ultra-high pressure wall breaking process (example 6), not only the total flavonoids are not at the maximum value, but also the SOD value is zero. On the contrary, the total flavone and SOD values are lower only by fermentation without wall breaking treatment. Only by the double process of wall breaking and fermentation (examples 1-4) can the total flavonoids and SOD values be kept in the high value range. The higher the ultrahigh pressure is, the higher the total flavone value is, but considering that the higher the ultrahigh pressure is, the higher the requirement on equipment is, the higher the energy consumption is, and the higher the cost is, the cost performance is considered in the actual process, so that the cost performance is considered in the preferred process.

Figure BDA0003996757220000161
* Data in parentheses are initial body weight.
If a large amount of alcohol is drunk for a long time, the incoordination between the spleen and the stomach can be caused, the symptoms such as nausea, vomiting, inappetence and the like are caused, the ingested alcohol is absorbed by the stomach and the small intestine and enters the liver through mesentery and portal vein, and the liver is the main target organ of the alcohol. Excessive drinking can result in increased permeability of hepatocytes, damage to hepatocytes and even necrosis. The metabolism of alcohol in the liver leads to enlargement of the liver, resulting in an increase in the liver index. The weight gain of the N group is 17.3%, which is a normal value, compared with the weight gain of the MH group, which is 8.0%, with the increase of the alcohol content, the weight is reduced and the increasing rule is presented. The weight of FAK is slightly changed and slightly increased compared with that of MM group, which indicates that alcohol causes the spleen and stomach to be suitable for reducing the weight, and the enzyme of Angelica keiskei Koidz has the effect of weakening or counteracting the side effect.
The liver indexes of the N groups are the lowest and belong to the normal condition, compared with the N groups, the liver indexes of the ML, MM and MH groups are obviously increased and are increased along with the increase of the alcohol content, and the dosage correlation is shown, which indicates that the alcohol has obvious damage to the liver function; compared with the group M, the liver index of the FAK group is reduced, and the Angelica keiskei Koidz enzyme FAK is proved to have a repairing effect on alcoholic liver injury.
Table 3 example 7 serum index technical index comparison
Figure BDA0003996757220000162
Figure BDA0003996757220000171
Because the liver is a metabolic organ of alcohol and fat, excessive intake of alcohol can cause the reduction of the metabolic function of liver fat, lead to the accumulation of lipid substances in the liver, further cause fatty lesion of the liver, and directly cause the increase of Triglyceride (TG) and Total Cholesterol (TC) indexes in blood. ALT and AST are two important transaminases present in the cytoplasm and mitochondria of the liver, and are normally present in low serum levels, and when hepatocytes are damaged or necrotic, ALT and AST infiltrate the blood. Therefore, the level of ALT and AST in serum is a specific indicator of the degree of damage to liver cells.
The N groups of indices were regarded as normal values, and the higher the four indices compared with the N group, the more serious the hepatic function damage. As can be seen from the data in Table 3, the TG indexes of ML, MM and MH groups increase with the increase of the alcohol content, and the alcoholic injury tends to increase. Meanwhile, the Angelica keiskei ferment FAK group can reduce four indexes compared with ML, MM and MH groups. Wherein, after FAK is dried, the TG content is obviously reduced, and the TC, AST and ALT contents also show the trend of reducing to different degrees. Therefore, the angelica keiskei enzyme FAK intervention has obvious improvement and repair effects on the alcoholic liver injury of mice.
Table 4 example 7 liver function index comparison
Figure BDA0003996757220000172
In clinical medicine, when ALT and AST are increased, liver damage is indicated; AST/ALT > 1, indicating liver necrosis. The N groups of indices were considered as normal values, and the higher the three indices compared to the N group, the more severe the liver function impairment was. As can be seen from the data in Table 4, the three indexes in the livers of ML, MM and MH groups show an increasing trend along with the increase of the alcohol content, but the indexes show an obvious decreasing trend after FAK intervention. Therefore, the angelica keiskei ferment FAK has a remarkable improvement or repair effect on the alcoholic liver injury of the mice.
It should be noted that the embodiments described in this patent only serve to put into effect one-to-three actions, and the processes implemented by changing the process conditions or adding other food materials and food additives thereof still belong to the protection scope of this patent application.
