Abstract:

To explore the shelf life of small yellow croaker under different storage temperatures, the effect of cold storage
(4 ℃), partial freezing storage (−3 ℃) and frozen storage (−18 ℃) on quality change of small yellow croaker was
investigated in the study. The total number of colonies, total volatile basic nitrogen (TVB-N) content, K values, actomyosin
content and total sulfhydryl content were measured. Based on the microbiological and physicochemical indexes, it could be
found that the shelf life of small yellow croaker in the cold storage and micro-frozen groups was 8 and 20 days respectively,
while those in the frozen storage group did not spoil at the end of the experiments (50 days).
