Abstract

Loss of market value of shrimp is mainly due to the formation of black spot called melanosis. A study was conducted for 14 days to determine the extent of melanosis and quality changes during that period of freshly har-vested whiteleg shrimp (Litopenaeus vannamei) under chilled storage (2?). Among quality parameters, total volatile basic nitrogen (TVB-N), thiobarbituric acid reactive substances (TBAR-S), were varied from 13.17 mg % to 44.50 mg % and 0.04to 2.57 mg malondehaldehyde/kg of fat respectively whereas melanosis score and metric chroma (C) exhibited significant increases during chilled storage (P<0.05). There was a slight increase in moisture, crude fat and pH from 73.96 % to 74.57 %, 1.05 % to 1.14 % and 6.52 to 7.60 respectively at 14th day of storage. Loss of protein from 22.51 % to 21.28 % may be due to decrease in available amino acids during chilled storage and total plate count (TPC) showed gradual increase of bacterial load up to 1.73*107 log CFU/g at the end of chilled storage. The sensory analysis by panellists indicated, the acceptability of white leg shrimp was up to 6 days in chilled condition and formation of black spot is one of the major parameter for rejection by the panellists.
