What is Tea Polyphenol?

There are several energetic hydroxyl groups (-OH) in the tea polyphenol particle, which can terminate the cost-free extreme domino effect in the body and get rid of superoxide ions, comparable to the impact of SOD. Tea polyphenols can get rid of superoxide anion and hydrogen peroxide complimentary radical The price is greater than 98%, revealing a significant dose-effect relationship, as well as its result is much better than that of vitamin E as well as C; tea polyphenols have protective impacts on cell membranes and cell walls, and also have evident results on eliminating lipid peroxidative free radicals.

The Efficacy of Tea Polyphenols

1. Assists to delay aging.

Tea polyphenols are the scavenging aspects of cost-free radicals in the body. Only a small amount of tea polyphenols is required to scavenge a multitude of cost-free radicals in the human body. Much more than comparable items. Tea polyphenols additionally have the ability to obstruct the excessive oxidation of fatty compounds, to ensure that energetic enzymes can be well eliminated.

2. Helps stop and also battle cancer cells.
According to research, tea polyphenols have a great ability to obstruct carcinogens such as nitrous acid. And also it has direct damage to cancer cells, as well as can likewise improve our body’s resistance. It has substantial effects on the avoidance and therapy of stomach illness and also gastric cancer cells.

3. Aids prevent as well as treat radiation injuries.
Tea polyphenols are referred to as the toughest anti-radiation substances, since tea polyphenols as well as its oxidized compounds can take in the damages brought on by radioactive materials effectively.

4. Helps to prevent as well as stand up to infections.
Tea polyphenols additionally have solid antibacterial as well as antiviral impacts. It has a great antiseptic result on pathogenic germs, which can be said to be an excellent alleviative impact for clients with inflammation.

Application Areas of Tea Polyphenols

Tea polyphenols are thoroughly used:
( 1) It can be included in pet fats such as lard, poultry fat, fish oil, butter, butter, mayo, veggie fats such as soybean oil, peanut oil, rapeseed oil, tea oil, corn oil, hand oil to stop the oil from going rancid. The improvement quantity is 0.005% to 0.05% of the oil material, as well as the impact is really considerable. (2) Tea polyphenols can be contributed to fried potato chips, fried immediate noodles, fried peanuts, fried fish along with different other foods according to 0.01% to 0.02% of the oil product, which has a significant antioxidant influence and also can stop The dubious scent throughout frying.
( 3) Throughout the processing of marine things, consisting of tea polyphenols at a dosage of 0.01% to 0.02% can have substantial anti-oxidation, anti-corruption and also odor free results.
( 4) Soak different meat products in a choice prepared with components such as tea polyphenols, the concentration of tea polyphenols is 0.05%-0.2%, the saturating time is 5-10min, and also the alternative temperature level is 60-70 ° C. Right now, the healthy protein as well as tea polyphenols externally of meat things will absolutely produce an impenetrable difficult flick. It can make meat items have antioxidant impact, can stop microbial development as well as safeguard against perishing. In the processing of pork, sausage, bacon and different other managed foods, including 0.01% to 0.02% of tea polyphenols can not just inhibit oxidative corruption, however furthermore decrease the web content of nitrosative Chemicalbook acid in maintained foods, making maintained foods A scrumptious scent appears.
( 5) Consisting of tea polyphenols to milk items can not only get rid of smell, nevertheless also stop oxidative corruption of oily compounds in milk products, and likewise can dramatically improve the preference of dairy products. The additive dosage is normally 0.01% to 0.05%.
( 6) Tea polyphenols can be included in many baked goods with high fat, high sugar in addition to oxidative wasting, such as moon cakes, biscuits, bread, immediate noodles, etc. It can stand up to oxidation and also rancidity, preserve quality and improve premium quality. Tea polyphenols can efficiently get rid of the beany smell of soybean things. The dose is 0.005% to 0.02%.
( 7) Tea polyphenols can be included in sweets such as consuming gum, soft candy, crisp sweet, sandwich candy, fruit sweet, and so forth, which can effectively exert their antioxidant along with fresh-keeping effects, in addition to have features such as eliminating foul breath and likewise avoiding dental cavity.

Determination of Tea Polyphenols in Tea Leaves

Tea polyphenol is one of the important chemical components in tea, and its content accounts for about 1/5 to 1/3 of the total dry matter of tea. The soup taste, color and aroma characteristics of finished tea are largely determined by the content of polyphenols, which play an important role in the quality of tea leaves.
In tea inspection, the technical measures to detect the content of tea polyphenols through chemical reactions are based on the characteristics of easy oxidation of tea polyphenols and the ability to produce colored precipitates with high iron salts, usually using potassium permanganate titration method and iron tartrate colorimetric method. . The former is a Chinese tea import and export inspection method. It uses the characteristics of tea polyphenols that are easily soluble in hot water and can be oxidized by potassium permanganate. Add 0.1% isatin solution, titrate twice with potassium permanganate, and titrate the tea soup first. The total amount of reducing substances in the total amount, and then titration to remove the amount of other reducing substances after tea polyphenols. The difference between the consumption of potassium permanganate in the two titrations can be used to calculate the content of tea polyphenols. Iron tartrate colorimetry is a method specified in my country’s national standard GB8313-87. According to the formation of violet-blue complexes between iron tartrate and tea polyphenols, the color of the complex solution is proportional to the content of tea polyphenols. Colorimetry, using optical density to express the content of tea polyphenols. When measuring, measure the extinction value E with a 1cm cuvette and a wavelength of 540nm. Calculation: the total amount of tea polyphenols (wet state)%=85.6×E when 2.5g of green tea sample is used, and the total amount of tea polyphenols (wet state)%=42.8×E when 5g of black tea sample is used. The conversion coefficients in the formula are 85.6 and 42.8, which can be corrected according to pure tea polyphenols or KMnO4 titration method.
