Abstract
1479731 Monosodium glutamate pentahydrate AJINOMOTO CO Inc 3 Sept 1974 [3 Sept 1973] 38543/74 Heading C2C Monosodium glutamate pentahydrate is made by (a) reducing to below 0À8‹ C. an aqueous solution of monosodium glutamate containing as impurities amino acids, organic acids, metal ions or colorants and (b) recovering from the cooled solution crystals of monosodium glutamate pentahydrate substantially free from impurities. The solution preferably has a pH of 5À5- 8À0 and is seeded with crystals of monosodium glutamate pentahydrate. It may be a clarified or unclarified fermentation broth.
