L-threonine has various applications in improving the taste of food, which are specifically as follows:
·Enhancing Umami Taste: L-threonine has a certain umami taste and can add a unique flavor to food. Appropriate addition of L-threonine to some soups and seasonings can enhance the umami taste, making the flavor richer and more mellow, and improving the overall taste of the food.
·Optimizing Texture: L-threonine can affect the texture of food. In baked goods such as bread and pastries, it can participate in the Maillard reaction, promoting the formation of an attractive color and a unique flavor on the surface of the bread. At the same time, it makes the internal structure of the bread softer and more delicate, delaying the aging rate of the bread and maintaining a good taste and texture. In meat products, L-threonine helps retain the moisture in the meat, making the meat more tender and juicy and improving the taste.
·Balancing Flavors: L-threonine can interact with other flavor substances to balance various flavors in food. In some compound seasonings or processed foods, it can regulate the balance of sweet, salty, sour, and bitter tastes, making the flavor of the food more harmonious and mild, reducing the abruptness of a single taste, and enhancing the taste quality of the food.
·Masking Unpleasant Flavors: For some food raw materials that have unpleasant flavors themselves, L-threonine can, to a certain extent, mask or improve these flavors. For example, in some plant protein products, there may be unpleasant flavors such as beany odor. Adding L-threonine can reduce the unpleasant flavor by binding with the off-flavor substances or changing their volatile properties, making the product taste better and more acceptable to consumers.
