Tea polyphenols (tea poRyphenoR TP) is a pure natural compound extracted from tea, accounting for about 18% to 36% of the dry weight of tea. It is also known as tea tannins and tea tannins. Generic term for polyhydroxyphenolic compounds.

The antioxidant effect of tea polyphenols is more than 20 times that of the traditional antioxidants vitamin C and vitamin E. Tea polyphenols can improve the body's immunity. When tea polyphenols are used in combination with vitamin E, the addition of vitamin E enhances the ability to scavenge free radicals, inhibits the generation of hydroperoxides, reduces the ability of tea polyphenols to scavenge free radicals, and plays a protective role. Polyphenols may repair damaged vitamin E.

Therefore, the combination of tea polyphenols and vitamin E not only has a significant synergistic antioxidant effect, but also has a stronger color protection effect than vitamin C after adding vitamin E to the meat. The color loss caused by polyphenols is further compensated, and the meaty sensory quality is improved.

Methionine is an important amino acid 1 The basic condition for maintaining good health and youth is a balanced diet. As we age, our body, spirit and emotions will undergo some changes. Appropriate use of methionine health supplements can improve the body's immune system, reduce diseases, and prevent aging. The role of methionine includes treatment of alcoholism, arthritis, depression, liver disease, and different mood disorders. It also supports and helps the liver, which is considered to be one of the important functions of methionine.

Methionine manufacturers

　　 Methionine is one of the essential amino acids that constitute the human body and participates in protein synthesis. Because it cannot be produced by itself in the body, it must be obtained from the outside. Lipid peroxide can damage the primary and secondary lysosomal membranes, release the acid phosphatase contained in the lysosome as a hydrolysis, and cause damage to important organelles such as cells and mitochondrial membranes. Methionine passes through a variety of Ways to combat these damages.
　　 Methionine is a sulfur-containing essential amino acid, which is closely related to the metabolism of various sulfur-containing compounds in the organism. When methionine is lacking, it will cause loss of appetite, slower growth or no weight gain, kidney enlargement and liver iron accumulation, and eventually lead to liver necrosis or fibrosis. Methionine can promote liver cell membrane phospholipid methylation, enhance membrane fluidity. Na+, K+ -ATPase pumps are strong, can reduce bile stagnation in liver cells, strengthen the transsulfide effect, and enhance cysteine ??in liver cells The synthesis of glutathione and taurine reduces the accumulation of bile acid in the liver, strengthens the detoxification effect, helps the liver cells to restore normal physiological functions, and promotes the resolution of jaundice and the recovery of liver function.
　　 Food without nutrition is of no value, so excessive intake of junk food will lead to malnutrition. However, nutritional supplements such as methionine can help the body get the necessary vitamins. Especially for the elderly, these nutrients are very important for health and longevity.

 In the actual process of raising pigs, pigs are prone to vitamin deficiency in winter. The main reason is the lack of green feed. In addition, some pig farmers have simple feed, lack of sunlight and poor air circulation, so pigs are easy to get vitamins in winter. Deficiency. 　　

Vitamin A deficiency. Dry skin, dull body hair, indigestion, reduced appetite, slow growth. Some have weakened vision and neurological disorders. In severe cases, cramps, turning circles, unsteady gait, ataxia, and even hindquarters can occur. The occurrence of this disease in sows can easily cause miscarriage or stillbirth, and the piglets born are blind. Even if the piglets born are normal in appearance, their physique is weak and easy to die. Prevention and treatment: 20 grams of pine needles, mashed juice or decocted juice, can be fed once in the feed, once a day, for several days; you can also feed more vitamin A-rich feed such as carrots and silage. 　　

Vitamin B deficiency. Growth retardation, vomiting, skin rash, hair loss, etc. When pantothenic acid is deficient, poor appetite, poor growth, diarrhea, coughing, loss of coat, dyskinesia, especially showing a "goose-walking" movement posture. When niacin is deficient, loss of appetite, weight loss, severe diarrhea, dermatitis, cracked skin, black scabs, neurological disorders, and anemia. Prevention: In the daily feed compounding, pay attention to adequate supply of vitamin B-rich feed. If corn is used as feed for a long time, it can cause niacin deficiency. The corn should be reduced in the feed and bran, silage, germinated feed and tuber juicy feed should be added.

The definition of vitamin and its role in animal feed Vitamins are a group of low-molecular organic compounds with different chemical structures, different nutritional and physiological functions. The content of vitamins in animal diets is about five ten thousandths, which is much less than other nutrients. Vitamins are neither a source of energy nor a structural substance of body tissues and organs, but they are indispensable to the normal life activities of animals. A small amount of vitamins can maintain the body's normal metabolism, growth and development, reproduction, resistance to diseases and normal survive. The main function of vitamins is to participate in the formation of highly active enzymes in animals. It has been proved that many kinds of enzymes contain vitamins. For example, vitamin B1 is a coenzyme of oxidative carboxylase, which participates in the sugar metabolism pyruvate decarboxylation reaction; vitamin B2 is a component of the prosthetic group of yellow enzymes and participates in biological oxidation in the body. If one of these vitamins is lacking, the body's corresponding metabolism will undergo abnormal changes. Most vitamins cannot be synthesized in animals, and only a few can be synthesized by animals themselves (microbes that are parasitic in the rumen of ruminants can synthesize multiple vitamins), but some vitamins are synthesized in very small amounts and cannot meet the normal needs of animals. It can be obtained from feed to ensure its normal growth, development and reproduction. 　　 It has been ascertained that 13 kinds of vitamins are needed in the diet of animals. Lack of any of them will cause abnormalities in the animals, such as growth retardation, decreased productivity, weakened disease resistance, and even death. Vitamin deficiency often has syndromes, and it is not easy to quickly determine which vitamin is lacking. Therefore, it is necessary to add sufficient amounts of various vitamins to the animal diet according to the standard to eliminate various unfavorable factors that destroy vitamins and avoid vitamin deficiency. .

 There are always many controversies among the people regarding the way of eating carrots. Some people think that raw carrots have good nutrition and the original taste, and the nutrition of cooked carrots will be lost; but some people think that cooked carrots are more nutritious, especially the carotene in carrots can play a better role. So, does cooked carrot contain carotene?

Carrot is a very nutritious food. It can not only enhance human immunity, fight cancer, reduce cancer chemotherapy response, but also affect the cardiovascular and cerebrovascular and various organs.

Play a protective role. In addition, scientific studies have shown that carrots contain carotene. This beta-carotene can not only significantly reduce the incidence of ovarian cancer, but also increase the activity of red blood cells, beautify the skin and resist aging. As the main nutrient in carrots, β-carotene exists in the cell wall of carrots and cannot be directly absorbed by the human body. The cell wall must be smashed by chopping and cooking to fully release β-carotene and be digested by the body. absorb. Therefore, in fact, cooked carrots not only have carotene, but can also increase the effectiveness of carrots several times, and this nutritional value is far from comparable to that of raw food. carotene 　　

In addition, studies have also shown that β-carotene in carrots is a fat-soluble substance, which is easier to be digested and absorbed by the human body after simple oil frying. Therefore, when eating carrots, you can not only cook them, but also simply fry them.

Indeed, experiments have shown that β-carotene itself not only has an antioxidant effect, but can also act as a pro-oxidant, which can promote free radical-induced oxidation reactions. This is related to the nature of carotene and the oxidation-reduction potential of the environment. It is based on in vitro cell experiments.

In fact, alcohol itself will increase the body's oxidative stress. A large number of studies have shown that drinking too much can induce a large number of free radicals in the body and lead to lipid peroxidation. This may also be one of the causes of alcoholic liver disease. However, does the β-carotene in carrots play an anti-oxidant or pro-oxidant effect when drinking alcohol?

A Taiwan study on the overall antioxidant status of β-carotene in alcohol-drinking mice found that the glutathione (GSH) concentration in the liver of the rats in the β-carotene supplement group was significantly higher than that in the alcohol-only group , And the presence of β-carotene helps to reduce the inhibition of glutathione peroxidase (GPX) by some peroxides, improves its antioxidant capacity, and does not appear to promote increased oxidation.

On the contrary, drinking alcohol alone caused the body to be severely oxidized. Experiments also showed that the mice in the group without β-carotene can only mobilize their own antioxidant system to defend themselves after drinking. Moreover, eating β-carotene supplements helps reduce alcohol-induced liver damage in mice compared with the control group (the dose given is 30% of the total energy of ethanol, and β-carotene is provided at 500ug per kilogram of body weight). for reference only.
