Procedure

26.5 g of zinc sulfate (0.17 M) is added to 1l of fermented broth of phenylalanine (27 g/l, 0.16 M) from which the microorganisms have been removed. The mixture is stirred slowly to completely dissolve the zinc sulfate. Ammonia water is gradually added to the dissolved solution to maintain the pH of 7.5 and then zinc phenylalaninate crystals are obtained (crystal wt: 32.4 g, purity: 99.2%).
