Plant extracts are one of the common types of raw materials used in food testing, cosmetic testing, pharmaceutical testing, health product testing, and feed testing. Tea extracts are active ingredients extracted from green tea leaves, including tea polyphenols (catechins), caffeine, aromatic oils, water, minerals, pigments, carbohydrates, proteins, amino acids, vitamins, etc. The bioactive abilities possessed by tea include immunomodulators, anti-genotoxic, anti-bacterial, anti-viral, and anti-diabetic, which have protective effects on human health. Due to the diversity of its components and benefits, tea can be used in various sectors. Therefore, for example, before tea can be used as a food additive, it is necessary to extract it to obtain its important compounds.
Plant extract testing is an important means of ensuring plant products, so the state has developed a strict quality control standard system for some common plant extracts, especially for applications in functional foods, food additives, cosmetics of plant origin, and other product extracts with very strict quality requirements. As a recognized leader in the field of tea testing, Lifeasible can develop the best solutions to test a wide variety of tea extracts, including but not limited to：
