Abstract:
... This work investigated the microbial community in Kantuan‐sliced chicken during retail storage at different temperatures (4 ± 1°C and 25 ± 1°C). Compared with the samples stored at 25°C, a lower storage temperature (4°C) could prolong the shelf life of Kantuan‐sliced chicken, as revealed by a lower change rate in pH value, total volatile basic nitrogen, and total viable counts. For the freshly pre ...
