What Is Oolong Tea Extract?

Advanced extraction methods provide a concentrated botanical element from partially fermented Camellia sinensis leaves. Tea polyphenols, catechins, and thearubigins are active.

Our extract was synthesised by water-ethanol extraction and spray drying to preserve bioactive ingredients. Polyphenolic chemicals not found in green or black teas are preserved via semi-oxidization.

Key specs: 80-350 mesh particle size, 4:1 to 20:1 extract ratio, and 98% polyphenol content. The production process follows ISO 20716 and Chinese Pharmacopoeia.

Measurable antioxidant capacity (ORAC values) for formulation predictability in this standard ingredient. You get a product that complies with international food-grade and nutraceutical-grade standards.

Functions

Metabolic health assistance

The catechin-rich composition of our extract improves the regulation of lipid metabolism and promotes healthy glucose control. Clinical studies have shown the importance of metabolic activity with polyphenol concentrations around 40%.

Antioxidant Protection

The polyphenols exhibit very strong free radical scavenging ability with DPPH radical scavenging rates around 85%. This feature provides protection to cellular frameworks from damage caused by oxidative stress.

Antimicrobial Efficacy

Lab tests indicate better suppression of Streptococcus mutans and other oral infections. It is useful in oral care formulations and in certain applications where the antibacterial power is more than that of chlorhexidine.

Nature Conservation

You gain from its capacity to inhibit lipid oxidation and enzymatic browning in food systems. This prolongs product shelf life without synthetic preservatives.

Application Fields

Industry	Primary Applications	Typical Dosage
Dietary Supplements	Weight management capsules, antioxidant tablets	200-500mg per serving
Functional Beverages	Ready-to-drink teas, sports nutrition drinks	0.5-2.0% concentration
Cosmetics	Anti-aging serums, skin brightening creams	1-5% in formulations
Food Processing	Natural preservatives, flavor enhancers	0.1-0.5% of total weight
Pharmaceuticals	Anti-inflammatory preparations, oral health products	As per formulation requirements

Oolong Tea Extract is suitable for use in protein bars, confectionary coatings and nutraceutical candies. The water-soluble versions are entirely soluble in beverage matrices without precipitation.
