Green Tea Extract Catechin Powder
What is Catechin?
Catechin, also known as tea tannins or catechols, is a phenolic active substance from the flavanol class extracted from natural plants such as tea leaves. It is the primary component of tea polyphenols (accounting for 75%-80%).
Basic Characteristics:
· Chemical Composition: Molecular formula: C₁₅H₁₄O₆, molecular weight: 290.28
· Physical Properties: White needle-shaped crystals (water-acetic acid system), melting point: 212-216°C
Solubility:
· Soluble in: hot water, ethanol, glacial acetic acid, acetone
· Slightly soluble in: cold water, ether
· Almost insoluble in: benzene, chloroform, petroleum ether
Source:
Naturally present in plants such as tea leaves, obtained through extraction and purification, it is one of the key components of tea's functional activity.
What Are The Benefits?
Excellent Antioxidant Properties
As the primary component of tea polyphenols, catechins exhibit remarkable antioxidant capacity. This natural oil antioxidant effectively neutralizes free radicals in the human body and maintains the integrity of cell membranes. Its remarkable antioxidant activity not only protects cells from oxidative damage but also demonstrates potential anti-aging benefits.
Cardiovascular Protection
Cardiovascular disease has become a major health threat in modern society, and catechins demonstrate unique protective value in this regard. Clinical studies have demonstrated that catechins can effectively regulate low-density lipoprotein cholesterol (LDL-C) levels in the blood and significantly reduce the risk of arteriosclerosis. Regular consumption of catechin-rich teas (such as green tea and black tea) can be an effective way to maintain heart health.
Broad-Spectrum Antimicrobial Effect
Several studies have demonstrated that catechins in green tea have inhibitory effects against a wide range of pathogenic microorganisms. Their antimicrobial spectrum encompasses both bacteria and fungi, with particularly significant antibacterial activity against bacteria. Notably, catechins maintain stable antimicrobial activity within a temperature range of 25-80°C, with acidic environments being particularly conducive to their effectiveness. Akagawa's team's research revealed its mechanism of action: EGCG and other monomeric components promote hydrogen peroxide (H2O2) production, which may be a key pathway for its antibacterial effects.
Promoting Fat Loss Through Exercise
Sports nutrition research has shown that consuming catechin-containing tea beverages (such as Pu'er tea or matcha) before exercise can significantly improve fat metabolism. This effect allows the body to more effectively mobilize and consume fat reserves during exercise, providing a scientific nutritional support solution for weight management and body shaping.
What Are The Benefits?
Personal Care
As a highly effective skincare active ingredient, catechins play a vital role in the cosmetics industry. Their unique cellular protective properties effectively protect against damage caused by UV rays and environmental pollution, while also offering multiple cosmetic benefits: anti-wrinkle, anti-inflammatory, and anti-pigmentation, providing comprehensive protection for the skin.
Health Food
Catechins are a key ingredient in health supplements due to their remarkable physiological activities:
· Exerting antioxidant properties by scavenging free radicals, they delay aging.
· Promoting fat metabolism and aiding weight management.
· With their anti-inflammatory and antibacterial properties, they can prevent tooth decay and improve eczema. These combined benefits have made them highly sought after in the dietary supplement market.
Food Industry
As a natural food additive, catechins exhibit excellent preservative properties:
· Effectively extending the shelf life of food
· Maintaining food freshness and nutritional value
· Preventing oxidative spoilage and protecting food's sensory qualities.
Their safety and effectiveness make them an ideal alternative to synthetic antioxidants.
