  The objective of this study was to evaluate the possibilities of ultra-fast air or cryogenic super chilling by dry ice (carbon dioxide) for prolongation the shelf life of fresh golden albino of rainbow trout (Oncorhynchus mykiss), and to evaluate its effect on the fish quality comparing with flake ice chilling. The gutted fish 2 h post mortem was packed in transparent plastic polyvinyl dichloride bags with zipper. The first (control) sample was stored chilled at 0°C to 4°C. The second group was cryogenic super chilled by dry ice (CO2) at -78°C with steam flow 0.5 m/s. The third group was ultra-fast super chilled with air at -20°C with air flow 3 m/s and stored at 2°C to 3°C. All samples were examined on 0, 7th, 14th and 21st day of storage. On 21st d of storage comparison between supper chilled samples and flake ice chilled control indicated lower as follows: p.. View More»
