Abstract

Canning of non-exportable small cultured shrimp (Penaeus indices) in oil, tomato sauce and brine was investigated in Hormozgan province. Our results indicated that the best method of canning of this shrimp was to precook it at 100'c for 2 minutes in 8% salt water which Contained 0.1% citric acid, then autoclaving the can for 12 minutes at 121°C. Results of an organoleptic evaluation showed that the shrimp packed in oil, tomato sauce and brine ranked by the taste panel as the first, second and third respectively. The changes in chemical composition, total bacteria count and Clostridium botulinum for the three samples of canned shrimp were also investigated. These changes were 18.90-22.59% for protein, 2.28-3.01% for fat, 70.7046.51% for moisture, 1.45-2.53% for ash, 19.64-29.35 mg/100g for TVN, 6.28i-7.03 for pH and zero for peroxide. The results for Clostridium botulinum and total count of bacteria for all samples of canned shrimp in three dilutions (0.1, 0.01 and 0.001) were negative .....
