Abstract: Shelf life of mud crab (Scylla serrata) meat during frozen storage at -20 0C for 200 days was determined by chemical andsensory evaluation. The results indicated that crab meat can be stored in an acceptable condition for 130 days. During frozenstorage, decreases in pH, moisture, total nitrogen and glycogen were noticed. Among the freshness parameters, lactic acid(212.6 to 388.8 mg%), Total volatile base nitrogen, TVBN (2.6 to 32.7 mg%), Trimethylamine nitrogen peroxide value,TMAN (1.01 to 17.55mg%) and Peroxide value, PV (0.84 to 27.93 milli moles of oxygen/kg of fat) increased, whereas nonproteinnitrogen, NPN (417.4 to 356.8 mg%) and alpha amino nitrogen, AAN (292.2 to 251.8 mg%) values decreased.Sensory evaluation of the frozen stored crab meat revealed the limits of acceptability of the product to be TVBN 18.2 mg%,TMAN 7.25 mg% and PV 15.13 millimoles of oxygen per kg fat.
