River crucian crucian carp shelf life prediction method

Abstract

The invention discloses a river crucian carp shelf life prediction method, by researches on sensory evaluation and K value change along with the extension of storage time of river crucian carp at different temperatures, a river crucian carp shelf life prediction model is established according to K value by use of Arrhenius equation, the method is novel and simple in operation, the river crucian carp shelf life prediction value can be calculated by substitution into a simple formula, the obtained the relative error of the river crucian carp shelf life prediction value is within + / -5%, and the accuracy is high. By measuring the K value change of the river crucian carp at different temperatures, corresponding quality energy level functions are analyzed, zero order chemical reaction kinetic is more suitable for reflecting the river crucian carp K value change rule, and is fully reasonable and persuasive, so that the method can be used to accurately predict the river crucian carp remaining shelf life, master and know the river crucian carp quality state and fresh degree.

Description

technical field [0001] The invention relates to a method for predicting the shelf life of aquatic products, especially a method for predicting the shelf life of freshwater fish, especially a method for predicting the shelf life of river crucian carp. Background technique [0002] The meat of river crucian carp is tender and sweet, with high nutritional value, but it is easily spoiled by factors such as the external environment, microorganisms and enzymes after death, and the strength of these effects is closely related to temperature. Generally, consumers buy fresh and live river crucian carp directly from vegetable markets or supermarkets. However, with the improvement of living standards and the acceleration of the pace of life, more and more convenient and fast aquatic products are more and more favored by consumers. Large supermarkets have gradually sold the slaughtered and packaged river crucian carp under ice storage conditions, which provides convenience for consumers...
