Method for predicting refrigerated carp freshness quality

Abstract

The invention relates to a method for predicting refrigerated carp freshness quality. The method comprises the following steps of: determining the shelf life of a product by researching the sense organ quality, chemical quality and microbiologic quality of refrigerated bred carp; describing a relationship between temperature and the carp freshness quality by adopting an index relative corruption rate equation model, wherein the relative corruption rate equation is LN(RRS)=0.14*T-0.0314; RRS is a relative corruption rate; and T is temperature (DEG C); and further building a carp freshness quality predicting equation in the temperature range (0 to 15 DEG C), wherein RSL is residual shelf life (day), SL(Tn) is the time (day) at the temperature of Tn, Tn is the temperature (DEG C), and RRS (Tn) is the relative corruption rate at the temperature of Tn. The quality predicting model is applied to monitoring the environmental condition of packaged foods, the food quality and safety information of the product during transportation and storage is provided, the production efficiency and product quality are effectively improved and a quantized basis is provided for reducing complaints from shopkeepers and consumers.

Description

technical field The invention belongs to the technical field of aquatic product processing and storage, in particular to a method for predicting the freshness and quality of refrigerated carp. Background technique Carp belongs to Cyprinidae and is widely distributed all over the country. It mostly inhabits the bottom of water bodies such as rivers and lakes. It mainly feeds on benthic animals. It is one of the main species of freshwater aquaculture in my country. The characteristics of strong market demand. At present, live fish is mostly used for circulation, but the transportation cost is high, and it is difficult to transport and sell in remote places, so it is difficult to meet the requirements of industrialization and large circulation. Therefore, the development of fresh fish logistics industry in the cooling chain is an effective way to solve the problem of excessive reliance on live fish circulation for farmed freshwater fish . Cooling chain is a special supply chai...

However, in reality, the quality of the final product varies, and the external conditions (especially temperature) of the product before consumption are also different from the ideal state, which often leads to miscalculation of the shelf life of the product
