Abstract
This paper examines the effect on biochemical and sensory parameters of Norway Lobster (Nephrops novergicus (L)) of two gas mixes—60/15/25 and 40/40/20 (CO2/O2/N2(%))—used as modified and controlled atmo- spheres for bulk storage at 1 �C. The biochemical results indicate that lots stored in the atmospheres kept good for up to 21 days as compared to only 14 days for the control. The biochemical parameters in the control increased significantly throughout storage. The same parameters only began to increase in the atmosphere lots on the 14th day of storage. In no case did the TMA concentration exceed 5 mg/100 g. The only lot rejected upon inspection in the course of storage was the control at 21 days. The parameters that scored worst in all lots were colour and odour, owing to the effect of the melanosis inhibitor. The lots stored in the 60/15/25 mix scored best irrespective of atmosphere type. There were no significant differences between controlled and modi- fied atmosphere samples.
