Green Tea Extract Tea Polyphenol

Green tea extract powder is the active ingredient extracted from green tea leaves, mainly including tea polyphenols, caffeine, aromatic oils, moisture, minerals, pigments, carbohydrates, proteins, amino acids, vitamins, etc. Tea polyphenols have the effects of anti-oxidation, scavenging free radicals, etc., significantly reducing the serum total cholesterol, triglycerides, and low-density lipoprotein cholesterol content of hyperlipidemia, and at the same time has the effect of restoring and protecting the function of vascular endothelium. The blood lipid-lowering effect of tea polyphenols is also one of the main reasons why tea can prevent obese people from losing weight.

QUICK DETAILS

How to extract polyphenols from green tea?

Step 1: Preparation

The first step in extracting polyphenols from green tea involves preparing the raw material. Fresh green tea leaves are first dried and crushed to increase the surface area, facilitating better extraction. The leaves are then subjected to a mild heat treatment, commonly known as "steaming" or "pan-firing," to deactivate enzymes that could otherwise oxidize and degrade the polyphenols. This step is crucial as it preserves the integrity of catechins and other active compounds in the leaves.

Step 2: Extraction

Once prepared, the green tea leaves are ready for the extraction phase. There are various methods to extract polyphenols from green tea, with the most common being solvent extraction, hot water extraction, and supercritical fluid extraction.

Solvent Extraction: Organic solvents such as ethanol or methanol are often used to extract polyphenols. The solvent dissolves the polyphenols from the tea leaves, leaving behind other less soluble compounds. The extract is then filtered to remove solid particles and concentrated.

Hot Water Extraction: This is the most traditional and common method, where green tea leaves are steeped in hot water at temperatures ranging from 60°C to 90°C. The catechins, along with other water-soluble compounds, dissolve into the water. The resulting solution is then filtered to remove residual plant material.

Supercritical Fluid Extraction: This method uses carbon dioxide (CO2) in a supercritical state, a phase between gas and liquid, to extract polyphenols. This technique is gaining popularity because it is highly efficient and produces extracts free from organic solvents, making it more environmentally friendly.

Step 3: Concentration and Purification

After extraction, the polyphenolic-rich solution must be concentrated and purified. The most common method of concentration is evaporation, which removes the solvent or water, leaving behind a concentrated polyphenol extract. Further purification may be necessary to isolate specific polyphenols, and techniques such as liquid chromatography or membrane filtration are often employed.
