Rutherford et al. (2007), prawns which had been vacuum-packed, were said to be ‘spoiled’ after 7 days of storage at 12 8C, however the prawns which had been gas-flushed with 100% CO2 did not show any sign of spoilage after a 15-day storage period. In the current study, prawn samples stored at 4 8C were described as being ‘very bad’ in quality after 14 days. All cooked samples had become very dull, slimy and moist as well as being very pungent in smell with black spots on the flesh. The raw sample had a noticeable loss of firmness and very pungent.
