Seasonings: As a umami enhancer, it is widely used in soy sauce, monosodium glutamate (MSG), chicken bouillon, oyster sauce, sauces, compound seasoning powders, soup bases, meat products, canned goods, and snacks.
Flavor Enhancement: It not only provides umami but also suppresses unpleasant odors (such as the metallic taste in canned goods or the retrograde taste of starch), and balances and harmonizes various flavors, making sweetness sweeter, saltiness milder, and meat flavor richer.
Home Cooking: In many parts of the world, families use MSG (whose main component is monosodium glutamate) to enhance the flavor of stir-fries and soups.
Pharmaceutical Industry: It can be used to prepare drugs, such as injections for treating hepatic coma (monosodium glutamate injections can lower blood ammonia levels).
Nutritional Supplements: As an amino acid supplement.
Cosmetics: Occasionally used as a moisturizing ingredient in skincare products.
