Abstract

 Cultured shrimps is one of the important export in fishries, produces in Islamic Republic of Iran. After catch the shrimp from ponds, they were kept in slurry ice tanks for 30 seconds immediately. sampling was performed before treatment of shrimp with SODIUM METABISULPHITE (SMB) and afterward kept in ice boxes using ice and shrimp samples which preserved layer by layer. The samples were transported 130 kilometers, from Tiab (near the Minab city) to Persian Gulf and Oman Sea Ecological Research Institute in Bandar Abbass for laboratory examinations. The estimated means for length and weight of shrimp were recorded 11.5±0.90 cm and 12.2±0.62 gr respectively. In this study, several aspects of SMB treatments for prevention of MELANOSIS were compared in order to produce high quality production for export purposes. The total absorption of SMB in muscle was estimated based of different time (0.5, 1, 2, 4, and 6 Minute), different temperature (0, 5, 15, and 25 centigrade), and different solutions with different SODIUM METABISULPHITE concentrations (1.25, 5, and 10 %) in sea water (38 ppt) as well. Titration method using Iodine treatment was performed in order to determination of the remained concentration of SO2 in shrimp muscle. The results showed that the concentration of SMB, the duration time of keeping the shrimp in solutions and the temperature of solutions had same influence for absorbing the SO2 in our samples. The obtained results showed that the SO2 concentration has increased using treatments from 30 second to 4 minutes but this indice has decreased for a time treatment using 6 minutes for this purpose. The results regarding to estimation of pH for treatments showed that this indice has a contrast level respect to the SO2 concentration for treatments as well. In the other word, the pH level has decrease during increasing the SO2 concentration and increase during decreasing the SO2 concentration. The best records for preserving the samples were recorded using 5% SMB concentration at 4 minutes in zero degree of centigrade. These achieved record could be due to sulfure dioxide absorbtion by samples for 251±7.51 mg/kg. Due to ice melting, a part of sulfure dioxid was released during transportation and the final sulfure dioxide absorbtion were decreased to the expected scale for 100 to 150 mg/kg. Using mentioned concentration would be suggested for shrimp before transportation.
