As an additive to improve food flavor: Studies have shown that theanine can improve the bitterness of coffee, cocoa, ginseng beverages, grapefruit beverages, beer, etc., and reduce the astringency of wine, so it can be used as a flavor improver for these foods.
Can be used as an additive for functional foods: Theanine can enhance the strength of alpha waves in the brain, making people feel relaxed and healthy, and has passed human trials. Therefore, it can be added to food as a functional ingredient in the future to develop functional food that relieves nervous tension and improves intelligence.
