To understand of the present state for temperature management of cold and frozen food transportation vehicles, we surveyed and measured the temperatures of eight transportation vehicles (including 3 small and medium and 5 large businesses) in Jeonbuk province, Korea. In the transportation vehicles of small and medium businesses, the mean temperature of cold and frozen foods was 8.35 ± 5.72℃ and - 3.45 ± 16.88℃; in large businesses, 3.92 ± 1.44℃ and and15.38 ± 2.98℃, respectively. In the difference of temperature by the locations within transportation vehicles, the difference in each cold and frozen was 2.40 ± 1.45℃ and 2.37 ± 2.52℃, as a mean. But there was not statistically significant difference in locations between cold and frozen (p greater than 0.05). In the difference of surface temperatures on various foods before and after door opening during the loading, the temperatures of cold and frozen foods increased by 0.55℃ and 1.18℃, as means, respectively. The temperature of foods over time and placement of cold and frozen foods in transportation vehicles were not consistently maintained at optimal values in distribution. Therefore, the development of time-temperature history (TTH) system technology at the distribution level for cold and frozen foods is required.
