Abstract:

Quality change and freshness of grass carp during storage at 4 ℃ were studied by measuring Ca2+-ATPase activity, pH, total volatile basic nitrogen (TVB-N) and total bacteria counts. Results indicated that Ca2+-ATPase activity in grass carp exhibited a declined trend during the storage and 67.74% reduction after storage for 9 days. In contrast, pH, TVB-N and total bacteria counts in grass carp revealed an increase trend during chilled storage.

Key words: grass carp, chilled storage, freshness, edible quality
