Abstract:

The aim is to provide technical support for wet rice noodle manufacturers to improve technology and optimize transportation and storage conditions. 2N+2L standard wet rice noodles developed by the research team, old wet rice noodles and market wet rice noodles were selected as research objects. The quality changes of wet rice noodles under different storage temperatures were investigated, the kinetic model was established and the shelf life of wet rice noodles was predicted. The results showed that the microbial and sensory indexes of the three kinds of wet rice noodles stored at 4℃, 10℃ and 25℃ had certain effects on the quality deterioration. The shelf life of 2N+2L standard wet rice noodles was 96 h, 72 h and 36 h at 4℃, 10℃ and 25℃, respectively, which was better than that of the other two products. On this basis, taking the overall acceptability of sensory quality as the limiting factor, the shelf life prediction models of the three kinds of products were established. It is verified that the relative error between the predicted value of the model and the measured value is less than 10%, indicating that the model is accurate and effective and has a good application prospect in the wet rice noodle industry.

Key words: wet rice noodle, limiting factor, overall acceptability, Arrhenius equation, shelf life prediction
