Physiochemical and Microbiological Quality of Lightly Processed Salmon ( Salmo salar L.) Stored Under Modified Atmosphere
Abstract Low‐temperature cooking, such as sous vide, has become a favored method for processing seafood. For this method to be applicable for retail products, combinations with other processing steps are needed to keep the products safe and durable while maintaining high quality. The present experim...
