Abstract: The quality changes of crucian carp stored in two different conditions: vacuum packing and non-vacuum packing, both at temperature of 3±1 ℃, were evaluated by sensory assessment, chemical(total volatile basic nitrogen and pH) and microbial (total viable counts) analysis. Storage in vacuum packing was more effective than non-vacuum packing, in delaying spoilage of the crucian carp. It was observed that the appearance score decreased with storage time, indicating the progressive loss of freshness in both vacuum packing and non-vacuum packing storage conditions. There was an increase in total viable counts over the period of storage. Bacteria grew more quickly in non-vacuum packing samples than in vacuum packing ones.

Key words: Carassius auratus, freshness, chilled storage
