Manufacturing

1. Raw Material Selection: Begin with high-quality green tea leaves, rich in EGCG, as the starting material.

2. Extraction: EGCG and other polyphenols contained in the leaves are extracted through water or a water-ethanol mixture. This process is often made at controlled temperatures, mainly to make EGCG extraction reach a maximum level and, at the same time, allow the least possible losses in activity.

3. Concentration: The extract is later concentrated under reduced pressure and removal of solvents. In this case, the concentration of EGCG will increase in the extract.

4. Purification: EGCG can be purified from the other polyphenols and impurities present in the extract by using suitable purification techniques, for example, column chromatography or membrane filtration.

5. Crystallization: Continue purifying EGCG through crystallization processes to attain a purity level reaching 60% EGCG concentration.

6. Drying: The drying is done through spray drying, freeze drying, or alternative routes until it dries to powder form, which is suitable for the intended applications.

7. Quality Control and Packaging: Stringent quality control testing is carried out to determine the EGCG content, purity, and quality of the extract. Packaging of the product should be carried out under conditions preserving its activity and stability, only after successful completion of these tests. This process ensures that the final product is highly concentrated with EGCG and that it meets the desired specification of not less than 60% EGCG content.

Applications

  • Many cosmetic and skin care products contain extracts of green tea with antioxidant abilities. Among the products where green tea extract is applied, there are products like creams, lotions, and serums, among others, with the ability to protect the skin from stressful atmospheric conditions.
  • This is used in the health supplement arena in very many formulas aiming to give general support to well-being due to its antioxidant properties. It comes in capsules, tablets, and powder forms.
  • In addition to its antioxidant benefits, green tea extract acts as an additive in pet food and supplements to ensure the pet's good health and vigor. Source: Green-tea extract in petfood

Geographical Specifications

The favorable topography for tea farming should be composed of gentle slopes, hence giving natural drainage; there will not be root rot. The steep slopes can, however, be used but require terrace farming to manage erosion and water runoffs. 

Ideally, Camellia sinensis grows well under high relative humidity ranging from 70 to 90%. A high relative humidity aids in maintaining leaf moisture and enhancing maximum photosynthesis within the plant.
