The purpose of this paper was to predict the growth dynamics of dominant spoilage bacteria for Spanish mackerel in different cold-chain logistics temperatures. The total viable counts (TVC), Shewanella counts and Pseudomonas counts were analyzed respectively, and the total volatile base nitrogen (TVB-N) and sensory quality index(QI)value at the end of the shelf life of Spanish mackerel were evaluated at 0, 4, 10 ℃ cold-chain logistics simulation. On the basis of the dynamic change of SSO with modified Gompertz equation, Belehradek equation was used to construct the prediction models of growth and shelf life for SSO in Spanish mackerel at …

To explore the scientific representation about the dynamic change of crab paste in pickling periods, fresh swimming crab was prepared for pickling the crab paste. Thereafter, the sensory and physical-chemical properties(pH, total volatile basic nitrogen, thiobarbituric acid, and free amino acid)and total plate count of different pickling periods (0, 6, 18, 30 and 42 h) were analyzed, and the correlation analysis and regression prediction model were carried out. The correlation analysis results showed that the free amino acid had no relation with sensory qualities. The flavor sensory properties such as fishy smell, sulfur smell, plumpness and flexibility were all significantly …

Studied the relationship between the filling factor of cigarette middle section and the radial compression amount when measuring the hardness of cigarettes, and then established the prediction model of cigarette hardness. The results showed that the goodness of fit of the model was over 98%, the standardized mean square error of the test was 0.6, and the average relative error was 3.7%. The prediction error of the model was far less than the normal fluctuation range of the index and the tolerance range specified in the product technical standard, and the prediction effect of the model was good. Meanwhile, the …
