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 & medium and 5 large businesses) in Jeonbuk province, Korea. In the transportation vehicles of small & medium businesses, the mean temperature of cold and frozen foods was 8.35 ± 5.72°C and ?3.45 ± 16.88°C; in large businesses, 3.92 ± 1.44°C and ?15.38 ± 2.98°C, respectively. In the difference of temperature by the locations within transportation vehicles, the difference in each cold and frozen was 2.40 ± 1.45°C and 2.37 ± 2.52°C, as a mean. But there was not statistically significant difference in locations between cold and frozen (p > 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°C and 1.18°C, 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.
