Preservation Mechanism of Carboxymethyl Chitosan Coating on Puffer Fish Quality during Cold Storage
The effects of caboxymethyl chitosan (CMC) coating on the quality of obscure puffer fish (Takifugu obscurus) during storage at 4℃ were studied. Changes in the total viable count of aerobic bacteria
weight loss
total volatile basic nitrogen
trimethylamine
sensory score and the texture indices such as firmness
springiness
resilience and chewiness of the refrigerated puffer fish were investigated. The results showed that compared with the untreated control samples
CMC treatment can suppress bacterial growth
reduce weight loss
and decrease changes in texture indices such as hardness
flexibility
resilience and chewiness
total volatile basic nitrogen
trimethylamine and sensory scores of puffer fish flesh
and extend the shelf life of puffer fish flesh from 4 days to 6 days during cold storage (4℃).
