dc.description.abstract Indian white prawn (Fenneropenaeus indicus) was vacuum packed in ethylene vinyl alcohol (EVOH) pouches and subjected to high pressure (HP) treatment of 250 MPa for 6 min at a ramp rate of 400 MPa min-1. Treated sample was stored in ice (2±1°C) along with untreated (control) sample to evaluate the changes in physicochemical parameters, mesophilic count and shelf life. Lightness (L* value) and yellowness (b*) value increased; whereas, redness decreased after pressure treatment. Significant increase of pH, hardness, FFA and TBA of prawn was noticed immediately after HP-treatment; however, TMA, TVB-N, K-value, relative activity of PPO and mesophilic count were reduced (p<0.05). During storage, hardness, pH, TMA, TVB-N, FFA, TBA values and mesophilic count increased; whereas, K-value and PPO were reduced in HP-treated sample (p<0.05). Tensile strength, elongation at break, oxygen transmission rate (OTR), carbon dioxide transmission rate (CO2-TR), water vapour transmission rate (WVTR), water extractives, nheptane of EVOH packing material have showed marginal changes after HP-treatment. Based on overall acceptability, control sample and HP-treated sample revealed a shelf life of 9 and 21 days, respectively during chilled storage. en_US
