Abstract:To establish the regression equation to predict the quality and safety dried-salted fish on storage depend on the change of biogenic amines, the change rule of biogenic amines of dried-salted fish during storage at room temperature and predictive modeling of shelf life, the changes and mutual relationship of physicochemical indexes, main microorganism and biogenic amines in dried-salted fatty hairtail and low fat threadfin bream during storage were studied. The preliminary establishment of dried-salted fish shelf life prediction model was used stepwise regression analysis method. The results showed that pH, water content and Aw in dried-salted hairtail and threadfin bream continued to decline during storage, total plate counts, lactic acid bacteria, micrococcus and staphylococcus contents were on the rise in three weeks, then decreased beginning from fourth week, while pseudomonas and enterobacterium contents were not checked out after the fourth week. Major biogenic amines, such as histamine, cadaverine and putrescine, were on the rise during storage. Five kinds of biogenic amines (histamine, cadaverine, putrescine, tryptamine, tyramine), total biogenic amine, relevant biogenic amine indices, physicochemical indicators and pseudomonas had a significant correlation with the storage time. Only pseudomonas was related to the biogenic amine and its related indicators. It is to provide a reference foundation for establish the system of shelf life about dried-salted fish.
