【Function】 In medicine, L-Aspartic acid is used as medicine of cardiopathy, hepar function accelerator, ammoniate toxicide, eliminating fatigure agent and the composition of amino acid injection. In industry, it is main material of L-Alanine and Asparagine. In food, it can be used as freshening agent, high sweetness agent of low heat and uncorrosing tooth, and elininating fatigure agent in drink of sports type.
