Abstract
The present disclosure relates to a crystallization method of branched-chain amino acids capable of sustainably cycling ammonia, and branched-chain amino acid crystal produced by the method.
Claims10
A crystallization method of branched-chain amino acids comprising:
- (a) mixing a reaction solution containing branched-chain amino acid crystals with ammonia to obtain a solution in which the branched-chain amino acid crystals are dissolved;
- (b) crystallizing the obtained solution to obtain a concentrate containing branched-chain amino acid crystals;
- (c) obtaining a mixed gas including water vapor and ammonia, generated in the crystallization process;
- and
- (d) reusing ammonia derived from the obtained mixed gas as ammonia of the process (a);
- wherein the process (b) and process (c) are carried out simultaneously or sequentially,
- wherein in the process (a), a pH of the solution in which the branched-chain amino acid crystals are dissolved is 9 to 12.
