Procedure
28.5 g of zinc acetate (0.16 M) is added to 1l of fermented broth of phenylalanine (25 g/l, 0.15 M), from which microorganisms have been removed, and stirred slowly to completely dissolve the zinc acetate. Ammonia water is gradually added to the dissolved solution so as to adjust the pH to 8 and then zinc phenylalaninate crystals are obtained (crystal wt: 31.4 g, purity: 98.4%).
