| Research Abstract |
DriedIwa-nori is one of the traditional foods and contains 5'-inosinic acid produced by 5'-AMPdeaminase. This enzyme in the DriedIwa-nori is stable by heat. In this study, contents of 5'-inosinic acid and free amino acids were measured. Activity of this enzyme was lost by heat under aqueous condition and Ca or Mg was necessary to express and stabilize this enzyme. Isolation and purification of this enzyme were tried by chromatography.
