Not AvailableThe effect of modified atmosphere packaging (MAP) at different gas concentration on chill stored pearl spot (Etroplus suratensis Bloch) was examined by means of nucleotide degradation and sensory evaluation. K value, a quality index for fish, the ratio of the sum of inosine and hypoxanthine to the sum of ATP and related catabolites expressed as a percentage, was determined until sensory rejection during storage up to 23 days at 0 - 20C. The C02 concentration did not affect the K values of pearl spot. K value increased linearly in samples stored under air and four different modified atmospheres. Identical K values were obtained for Pearl spot packed in either aerobic or carbon dioxide modified atmosphere. K values were independent of sensory spoilage and correlate only with the length of storage of pearl spot packed under MAP.Not Availabl
