Fillets of five fish species were irradiated at 0,1 and 3kGy to investigate whether the K-value test of freshness can be applied to irradiated fish. Following irradiation, the fillets were stored on ice and sampled regularly for K-value analysis. Hypoxanthine (Hx) and total nucleotide content were also determined on fillets of two species. K-Values of irradiated fillets were generally lower than those of unirradiated controls. Hypoxanthin levels paralleled the K-value changes. These results indicated that quality standards based on K-values or Hx levels that have been set fro unirradiated species cannot be directly applied to fish that had been irradiated. Total nucleotide content did not appear to be affected by irradiation. 相似文献
