Abstract

Shrimp was freeze-dried in Stokes lab. model at platen temp. 45 degree C, total drying time was 12 h; moisture content of the dried product was 3.0%. Taste panel studies indicated very low acceptability for texture evaluation of the conventionally air-dried shrimp. Freeze-dried shrimp were far superior to air-dried shrimp but slightly inferior in quality to fresh shrimp. Though the rehydration ratio for freeze-dried shrimp is 5 times as compared with 1.2 for air-dried shrimp, about of the water could be easily expressed from the rehydrated freeze-dried shrimp by applying slight manual pressure. The rehydrated shrimp shrunk considerably on cooking and their texture was rather tough when compared with the freshly-caught shrimp. Shrimp that were freeze-dried after mild blanching gave a finished product with attractive pink colour and at the same time occupied less space.
