تاثير اشعه گاما روي شاخص بازهاي ازته فرار (TVB-N) و خواص حسي ميگوي سفيد هندي (Penaeus indicus)

Effect of gamma irradiation on total volatile base nitrogen (TVB-N) and sensory attributes of Indian white shrimp (Penaeus indicus)

Effect of gamma irradiation on total volatile base nitrogen (TVB-N) and sensory evaluations of Indian white shrimp (P. indicus) held frozen (-18°C), for 9 months and every 1.5 months, was studied. TVB-N values increased gradually during the storage period and decreased with increasing irradiation dose that reached 20.64, 27.45, 34.14, 35.45 mg N/100g flesh, respectively for irradiated and control samples. Also with organoleptic evaluation indicated that, shelf-life of 5, 2.5 KGy samples increased up to 3 months and 1 KGy samples increased up to 1.5 months compared to control samples.
