Function and application:
L-Alanine can improve the nutritional value of food, in various foods and beverages, such as: bread, iced cakes, fruit tea, dairy products, carbonated drinks, sorbets, etc. Adding 0.1~1% of alanine can significantly improve the utilization of protein in foods and beverages, and because alanine has the characteristics of being directly absorbed by cells, it can quickly recover from fatigue and refresh the spirit after drinking.
Improve the taste of synthetic sweeteners, increase sweetness and reduce dosage. Adding 1~10% alanine to the compound sweetener can increase the sweetness and soften the sweetness as natural sweeteners, and improve the taste.
Alanine is also one of the raw materials for the synthesis of high-sweetness Alitame (L-aspartyl-D-alanine, 600 times the sweetness of sucrose).
Used as a flavor enhancer. It can increase the seasoning effect of condiments; it can also be used as a sourness corrector to improve the sourness of organic acids.
L-alanine is an important raw material for the synthesis of VB6.
The “Amino Acid Injection-800″ with L-alanine as the main ingredient treats liver and encephalopathy and prompts patients with hepatic coma to wake up quickly. It is also a diuretic medicine.
