Study on Textural, Microbial and Sensory Quality of Blast Frozen Pangasius Fish Fillets Under Frozen Storage

Abstract Pangasius fish is one of the rapid growing fresh water species in aquaculture. This study was aimed to assess the microbial number, physical quality and sensory evaluation of the Pangasius fish fillets from Nepal. Pangasius fish were collected from Chitwan and Nawalparasi districts, fill...
