Method for evaluating shelf life of cooling pork at fluctuating temperature

Abstract

The invention relates to a method for evaluating the shelf life of cooling pork at fluctuating temperature. The method comprises the following steps of: (1) sample microorganism and sensory analysis; (2) microorganism growth prediction models; and (3) application and verification of the prediction models at the fluctuating temperature. The method has the advantages that a predictive microbiology method is applied to analyze the growth situations of aerobic bacteria in the cooling pork at different time points under different temperature conditions and establish the microorganism prediction models of the cooling pork at different storage temperatures so as to evaluate the edible safety of the cooling pork; the established prediction microorganism dynamical-models can effectively predict the shelf life of the cooling pork at the temperature of 4-15 DEG C; and a strong technical support is provided for monitoring and tracking the shelf life of the cooling pork under the environment condition with the fluctuating temperature in real time.

Description

technical field [0001] The invention relates to the field of meat product storage, in particular to a method for evaluating the shelf life of cooled pork under fluctuating temperatures. Background technique [0002] Chilled pork is welcomed by consumers because of its good taste and safety. As the main meat consumption food of Chinese consumers, the safety of pork products has received extensive attention and attention. Therefore, the development of technical methods that can quickly and effectively evaluate the shelf life and safety of chilled pork is of vital importance not only for food consumers, but also for retailers and the meat industry. [0003] In the case of proper temperature control, the chilled pork is always at a low temperature of 0-4°C, which inhibits the growth of microorganisms in the meat to a certain extent. However, if the cold chain system is not perfect, improper control occurs in the process of storage, transportation, and sales, resulting in change...
