What are Catechins Powder?

Green tea extract Catechins Powder | Tea Polyphenols is a flavan-3-ol, a natural phenol and antioxidant. It is a secondary plant metabolite. It belongs to the group of flavan-3-ols or simply flavanols, part of the chemical family of flavonoids.

The rearch of green tea

The research aimed at finding the active compounds in green tea revealed that its protective effects are due chiefly to catechins. Tea contains four main catechin substances: EC, ECG, EGC, and EGCg, all of which are inclusively called catechin. Epigallocatechin gallate (EGCG) is the most powerful of these catechins. EGCG as an antioxidant is about 25-100 times more potent than vitamins C and E. One cup of green tea provides 10-40 mg of polyphenols and has antioxidant effects more excellent than a serving of broccoli, spinach, carrots, or strawberries.

Protecting the body from oxidative damage

The high antioxidant activity of green tea makes it beneficial for protecting the body from oxidative damage due to free radicals. Research shows that green tea may help the arterial wall by reducing lipids. Green tea can protect against experimentally induced DNA damage and slow or halt undesirable cell colonies’ initiation and progression. Studies show evidence that green tea provides immunoprotective qualities, particularly in patients undergoing radiation or chemotherapy. White blood cell count appears to be maintained more effectively in patients consuming green tea than non-supplemented patients.

Antioxidants catechins

The oxidation of catechins is minimal, and hence they can serve as antioxidants. Researchers believe that catechin is effective because it easily sticks to proteins, blocking bacteria from adhering to cell walls and disrupting their ability to destroy them. Viruses have ‘hooks’ on their surfaces and can attach to cell walls. The catechin in green tea prevents viruses from adhering and causing harm. Catechin reacts with toxins created by harmful bacteria (many of which belong to the protein family) and harmful metals such as lead, mercury, chrome, and cadmium.

Tannin in green tea

Tannin in green tea is mostly catechin and is a key component in its taste, providing astringency. The amount of catechin tends to increase as the season progresses. Spring tea (first crop) contains 12-13% catechin (13-17% as tannin) while summer tea (third crop) contains 13-14% (17-21% as tannin). If compare the leaf order, younger leaves include more catechin than mature ones. First leaves contain 14%, second 13%, third 12%, and fourth 12%.

Types of Catechins

Green Tea Catechins Polyphenol Catechins Powder are a type of polyphenol and are the main astringency component in green tea, There are four main types of catechins found in green tea leaves.

  1. Epicatechin
  2. Epigallocatechin
  3. Epicatechin gallate
  4. Epigallocatechin gallate

In addition, during the manufacturing process for tea beverages, owing to heat processing, some catechins change form.

  1. Epicatechin → Catechin
  2. Epigallocatechin → Gallocatechin
  3. Epicatechin gallate → Catechin gallate
  4. Epigallocatechin gallate → Gallocatechin gallate

Green Tea Catechins oxidize extremely easily.

Green Tea Catechins oxidize extremely easily. In green tea, since the process for making crude tea involves halting the action of oxidizing enzymes, most of the catechins remain unoxidized. In oolong and black teas, oxidizing enzymes’ action produces oxidized polymers. Unlike catechins, which are colorless in an aqueous solution, these oxidized catechins become orange or red, and This is what gives oolong and black teas their distinctive reddish color.

Catechin content

Fresh green tea has a catechin content of approximately 12-14%, while Nibancha has a catechin content of approximately 14-15%. The catechin content of young shoots is higher than mature leaves.

How is Catechins produced in green tea?

The roots of the green tea produce Catechins and migrate to the leaves. Farmers cover green tea tree to make teas high in theanine and low in catechin.
