An Assessment of Bio-Chemical Quality of Ice-Stored Tiger Shrimp (Penaeus Monodon) From Coastal Bangladesh

Abstract

An investigation focused on bio-chemical evaluation of Tiger Shrimp, Bagda (Penaeus monodon) of different ranges of marketable size collected in fresh condition from Koiya Bazar that stored in ice at a ratio of 1:2 of shrimp: ice at Fisheries and Marine Resources Technology (FMRT) Discipline of Khulna University, Bangladesh. Iced storage trial was carried out over 14 days and analyzed TVB-N, TMA, and pH. The range of TVB-N, TMA, and pH are between 2.692 ± 0.172 mg/100g to 16.118 ± 0.032 mg/100g, 5.385±0.026458 mg/100g to 10.764±0.036056 mg/100g, and 6.6 ± 0.1 to 7.2 ± 0.152 respectively. Highly positive relationship was observed between storage days and TVB-N values (r2 = 0.7722), TMA values (r2 = 0.7095), and pH value (r2 = 0.9007). The overall results of TVB-N and TMA-N contents of P. monodon stored in ice rose as spoilage advanced. pH also increased with the increase in spoilage cause by bacteria. There are some discrepancies that should be that need for further investigation, particularly for daily de-gassing, prevention of the formation of bubbles in the reagent line.
