Green Tea Extract Catechin
What is Catechin?
Catechins, also known as tea tannins and catechols, are the general term for flavanols in tea. They are a class of phenolic active substances extracted from natural plants such as tea. Catechins are the most important type of tea polyphenols, accounting for 75% to 80% of the content of tea polyphenols.
Foods with high catechin content include tea leaves and fruits, among which tea leaves include green tea and black tea, and fruits include strawberries, apricots, peaches, cherries, mangoes, etc. In daily life, the above foods can be eaten appropriately to supplement catechins.
What Are The Benefits?
1. Antioxidant effect
Catechin is an important component in tea. It belongs to polyphenols and is a natural oil antioxidant. It has high antioxidant activity and can scavenge free radicals produced by the human body and protect cell membranes. Catechin has high antioxidant activity and has the effect of delaying aging.
2. Reduce the risk of cardiovascular disease
Cardiovascular disease is really a major health killer in modern society, but catechin is a good helper in preventing such diseases! Studies have shown that catechins can significantly reduce LDL cholesterol levels in the blood, thereby reducing the risk of arteriosclerosis. This means that moderate consumption of green or black tea, which are rich in catechins, can help protect our heart health.
3.Antibacterial effect
Studies have shown that catechins in green tea can inhibit the growth and reproduction of most pathogenic strains. Catechins have inhibitory effects on both bacteria and fungi, but the effects are different. The inhibitory effect on bacteria is stronger than that on fungi and molds. Through the determination of catechin thermal stability, it was found that when the temperature is 25-80℃, catechins have the best antibacterial effect and are not affected by temperature conditions. The pH stability experiment showed that catechins are more stable under acidic conditions than under alkaline conditions.
Akagawa et al. determined the H2O2 content in green tea, black tea and coffee. The study found that the more polyphenols in the beverage, the more H2O2 is produced. The experiment also found that the four monomers EGCG, ECG, EGC, and EC can all produce H2O2, so the antibacterial effect of catechins may be related to the H2O2 produced.
4. Improve the fat-burning power of exercise
Studies have shown that moderate intake of catechin-rich tea drinks, such as Pu'er tea or matcha, before exercise can significantly increase fat metabolism. This means that during exercise, our bodies are able to burn more fat, thereby achieving weight loss and body shaping effects more effectively.
Applications
Catechins are used in many fields and show great application potential:
1. Skin care ingredients: Catechins can reduce the damage of cells caused by environmental pollution and ultraviolet radiation, and have anti-aging, anti-wrinkle, anti-inflammatory and anti-pigmentation effects. They are often used as active ingredients in skin care products.
2. Health care products: Catechins are also widely used in the field of health care products. Due to its strong antioxidant properties, catechins can help remove free radicals in the body, reduce oxidative damage, slow down the aging process, promote metabolism, increase fat oxidation energy supply, and thus achieve a weight loss effect. In addition, catechins also have anti-inflammatory, antibacterial, caries prevention and eczema treatment effects, which make them an important ingredient in health care products.
3. Food additives: Catechins can be added to food as a natural antioxidant to extend the shelf life of food and maintain the freshness of food. It can remove free radicals in food and prevent food from oxidation and deterioration, thereby maintaining the nutritional value and sensory quality of food.
