L-theanine powder is a natural amino acid extracted from green tea, with the chemical name N-ethyl - γ - glutamine. It exists in the form of white crystalline powder, odorless and slightly sweet, and is a unique free amino acid in tea, accounting for 1% -2% of the dry tea weight. As a food additive, L-theanine powder can significantly enhance product flavor and provide health benefits.
In food applications, L-theanine powder exhibits excellent multifunctionality. It can be added as a seasoning to candies, beverages, and baked goods, effectively improving taste and reducing bitterness. In coffee, cocoa, and tea drinks, it can enhance flavor levels, provide natural sweetness, and replace artificial additives. In addition, L-theanine powder is also used in the development of functional foods, such as beverages to relieve anxiety or nutritional supplements to enhance memory, meeting consumers' demand for natural health ingredients.
The extraction process of L-theanine powder from green tea combines traditional and modern technologies, with the core being efficient separation and purification. The traditional method mainly uses the water extraction method. After crushing the green tea raw materials, soak them in pure water at 80-90 ℃ for 45-60 minutes, filter to remove impurities, and then obtain the crude product through concentration and crystallization steps. Modern technology introduces enzymatic hydrolysis, which first uses biological enzymes to treat tea powder, and then combines supercritical fluid extraction and nanofiltration purification technology to significantly improve extraction efficiency and product purity. For example, enzymatic hydrolysis can increase the content of theanine from 1% -2% in raw materials to 20% -30% in extracts, while reducing the risk of heavy metal residues. The entire process focuses on environmental protection and sustainability, such as using tea polyphenol industrial waste liquid as raw material to reduce resource waste. With the advancement of technology, the production of L-theanine powder by fermentation method is gradually becoming popular. Through microbial transformation, large-scale and standardized supply can be achieved, providing a more stable source of raw materials for the industry.
