Abstract In this research, 16 samples of pork, beef, mutton, chicken, fish and shrimp directly provided by producers or procured from supermarkets or farmer’s markets were stored at ?40 ℃ for up to 360 days. Changes in the sensory, physicochemical and nutritional properties of the samples were measured during the storage period. The results showed that sensory evaluation score, together with freshness, decreased with storage time for all samples, but most of the samples were still edible; water content fluctuated in the standard range; the contents of nutrients such as proteins, fats and fatty acids fluctuated in a small range without significant changes. In conclusion, meat, fish and shrimp were still edible after 360 days of storage at ?40 ℃.
