Evaluation of Storage Stability and Quality Changes of Fish Muscle (Pangasianodon hypothalamus) Preserved in Fabricated Portable Solar Cooler and Domestic Refrigerator

Background: This study was carried out to evaluate the quality changes and storage stability of fish muscle (Pangasianodon hypothalamus) preserved in fabricated portable solar cooler and domestic refrigerator. Methods: Fish muscle from Pangasianodon hypothalamus were studied, keeping it in a fabricated portable solar cooler and in a domestic refrigerator at 5°±1°c to compare the shelf-life and quality of fish muscles. The fish muscles were packed separately in LDPE (low density polyethylene) packets and stored in a solar cooler and domestic refrigerator up to 7 days to compare the different physico-chemical, microbiological and sensory parameters on 0th , 3rd and 7th day. Results: The results revealed that there were no significant changes (P greater than 0.05) of different parameters during the storage periods in compare to solar cooler and domestic refrigerator. Finally, from the present study it can be concluded that the preservation of fish in a portable solar cooler system is thus economically suitable, feasible and acceptable up to 7 days as compared to domestic refrigeration method at controlled temperature.
