What is White Tea Extract ?
White tea extract is derived from white tea, one of the six major types of tea in China. It is mainly produced in Fuding, Zhenghe, Jianyang and other places in Fujian. Its core raw materials are tender buds and leaves of Baihao Yinzhen, Bai Mudan and other teas. The uniqueness of white tea lies in its processing technology: it only goes through two processes, withering and drying, without frying or kneading, to retain the natural form and white hair of the branches and leaves to the greatest extent, making the amino acid content 1.13-2.25 times higher than other types of tea, and the accumulation of flavonoids increased by 16.2 times. In recent years, with the innovation of technology, supercritical CO₂ extraction, bio-enzymatic hydrolysis and other processes have increased the extraction rate of active ingredients such as tea polyphenols and catechins to 96.75%, an increase of 35% over traditional methods;
The efficacy of white tea extract comes from its complex combination of natural ingredients. 64 active substances have been identified by ultra-high performance liquid chromatography-mass spectrometry (UHPLC-Q-Orbitrap-HRMS), covering six major categories of compounds:
Polyphenols: White tea extract catechins and epigallocatechins, accounting for 65%-80% of the total tea polyphenols, with antioxidant function
Flavones: quercetin and kaempferol, the content is 16.2 times that of other teas.
Amino Acids: theanine, the content of silver needle white needle is 49.51mg/g.
Polysaccharides: tea polysaccharide complex, composed of 8 monosaccharides such as rhamnose and galactose.
Volatile Oils: linalool, phenylethanol, solid phase microextraction method to identify 35 aroma components
Trace Elements: zinc and selenium, synergistically enhance immune regulation function。
What Are The Benefits Of White Tea Extract ?
1. Health Protection: Multi-Dimensional Biological Activity Verification
Antioxidation and anti-aging:
White tea polyphenols have 4 times the ability to scavenge free radicals as vitamin E, significantly reducing UV-induced DNA damage and delaying skin collagen degradation. Clinical trials have shown that topical skin care products containing white tea extract can reduce wrinkle depth by 40%.
Immunomodulation and anti-cancer:
Ethylamine produced by the decomposition of theanine activates “gamma-delta T cells”, increases interferon secretion by 5 times, and enhances antiviral ability; combined with drugs such as sulindac, it can inhibit tumor proliferation and reduce chemotherapy side effects.
Metabolic disease management:
Tea polysaccharides can reduce blood sugar levels by increasing insulin sensitivity; in animal experiments, the level of malondialdehyde (MDA) in liver injury models decreased by 40%, and the liver protection effect is better than silymarin.
2. Skin Science: Photoprotection And Repair Revolution
A study by Case Western Reserve University in the United States found that:
Langerhans cell protection: When white tea extract is applied to the skin and exposed to ultraviolet rays, the survival rate of Langerhans cells (immune surveillance cells) increases by 87%, repairing the immune function damaged by sunlight;
Anti-inflammatory and whitening: inhibits tyrosinase activity and reduces melanin production; the inhibition rate of Propionibacterium acnes exceeds 90%, which is suitable for anti-acne products for sensitive skin.
What Are The Applications Of White Tea Extract ?
1. Functional Foods And Health Products
Sugar substitutes and health foods: Tea polysaccharides have the property of regulating blood sugar
High-end tonics: Cordyceps white tea combines cordycepin and white tea polyphenols, becoming a very popular high-end supplement in recent years.
2. Beauty And Personal Care Industry
Sunscreen and anti-aging: Many well-known brands add white tea extract to sunscreen, which cooperates with zinc oxide to increase SPF value and repair photoaging damage;
Oil control and acne removal: The patented ingredient DISAPORETM (added amount 0.5%-2.5%) regulates sebaceous gland activity, and clinical trials have confirmed that it can turn oily skin into neutral.
3. Medical And Agricultural Innovation
Alternative antibiotics: Adding 4% white tea extract to aquatic feed, the weight gain rate of carp reached 155.1%, and the lysozyme activity increased by 69.2 U/mL;
Adjuvant treatment of chronic diseases: Andrographolide-white tea compound preparation has entered Phase II clinical trials for diabetic retinopathy and liver fibrosis.
4. Environmental Protection And New Materials
Tea residues are converted into biodegradable packaging materials to reduce resource waste; volatile oil components (such as linalool) are used as natural preservatives to replace chemical synthetic products.
