Product Description

L-Alanine is a white crystalline powder, an essential natural amino acid with a slight sweet taste and no peculiar odor. It is easily soluble in water and slightly soluble in ethanol, with stable chemical properties under normal storage conditions. It is widely used as a nutritional fortifier to supplement amino acid nutrients in food and health care products. It can effectively adjust and improve the flavor of food, soften bitter taste and balance the overall taste system. It also has a good buffering effect to stabilize the pH value of the formula and maintain product sensory quality. It is a key raw material for preparing compound amino acid solutions and various nutritional supplements. It participates in human protein synthesis and supports normal body metabolism. It is commonly added into functional drinks, seasonings, baked goods and oral nutritional formulations. It meets relevant food grade standards and can be safely applied in permitted food applications. It can be compounded with other amino acids to realize more comprehensive nutritional matching.

Functions and Effects

L-Alanine is a vital amino acid for human nutrition and can be used for amino acid fortification in food and nutritional supplements. It helps to adjust and improve the taste of food, soften bitter notes and balance the overall flavor system. It possesses buffering capacity to regulate pH value and stabilize the sensory characteristics of finished products. It acts as an important raw material for producing compound amino acid preparations and health care products. It participates in human protein synthesis and supports normal metabolic activities, and also promotes the absorption of other nutrients in the body. It can provide rapid energy supply for muscle tissues during physical activity. It helps maintain stable blood sugar levels under energy consumption conditions. It can be blended with other amino acids to achieve more comprehensive nutritional matching. It also reduces undesirable aftertastes in beverage and seasoning formulations.

Application Fields

L-Alanine is widely used in food, beverage and health product industries as a nutritional fortifier and flavor modifier. It is commonly added into functional drinks, oral liquid supplements and sports nutrition products to supplement amino acids. It can be applied in seasonings and savory food to optimize taste and reduce bitter aftertaste. It serves as a key raw material for compound amino acid formulations used in nutritional supplements. It is suitable for baked goods and dairy products to enrich nutrition and improve sensory quality. It can also be used in biochemical reagents and pharmaceutical intermediate production. It can be mixed with other amino acids to develop customized nutritional premix powders. It complies with food additive regulations for safe use in all approved food categories. It is applied in animal feed to enhance the nutritional value of feed formula. It helps improve the palatability of feed and support animal growth performance.
