Method for establishing river carp shelf life prediction model by using TBA

Abstract

A method for establishing a river carp shelf life prediction model by using TBA is that the river carp shelf life prediction model is established by researching sensory evaluation on river carps at different temperatures and change of the TBA with storage time prolonging and utilizing an Arrhenius equation according to the TBA. The method is novel, operation is simple, the river carp shelf life prediction model can be obtained through substitution of a simple formula and calculation, a relative error of an obtained shelf life prediction value is within a range from -5% to +5%, and the accuracy is high. The zero-level chemical reaction kinetic is confirmed and selected by measuring the TBA change of the river carps at the different temperatures to reflect a river carp TBA change rule, and the method has sufficient reasonability and persuasion. Therefore, the method can be used for accurately predicting the remaining river carp shelf life and mastering and learning the quality condition and freshness of the river carps.

Description

Technical field [0001] The present invention involves a method of predicting aquatic product shelf periods, especially the prediction method of freshwater fish shelf period, especially the method of river catfish shelf period. Background technique [0002] River catfish has a delicate meat, sweet meat taste, and high nutritional value. However, it is easy to be corrupted by the effects of external environment, microorganisms and enzymes. The strength of these effects is closely related to the temperature.Generally, consumers are purchased directly from the vegetable market or supermarket. However, with the improvement of living standards and the acceleration of the rhythm of life, large supermarkets have gradually sold the packaged river catfish under ice.Consumers provide convenience.This way of selling needs to grasp the quality changes and remaining shelf periods in real time. [0003] The sulfurbal acid value TBA can reflect the degree of fat oxidation of the river catfish du...
