Effect of Cold Chain Transportation on Assemble?able Cold?storage Incubator
摘要
Abstract
Cold?storage incubators that are easy to disassemble and assemble may become the development trend of the future. An experi?ment on the effect of cold?chain transportation was performed on an assemble?able cold?storage incubator with pleurotus ostreatus ( oyster mushrooms) . During the experiment, the temperatures of the air, the center of the pleurotus ostreatus, and the cold?storage agent in the incubator were tested;then, the heat?leakage rate from the gaps in the cold?storage incubator assembly was determined. Meanwhile, the pleurotus ostreatus were sampled every 30 hours to make a sensory evaluation and the nutritional indicators were tested to judge the effect of the cold?chain transportation. The results show that, in an ambient temperature of 25℃, it takes 56 hours for the coolant to completely liquefy, which is eight hours less than that estimated. This means that the required coolant amount, which can be adjusted by a factor?cor?rection method, was actually larger than the estimation. Moreover, the heat?leakage rate from the gap increased to 12. 97％, which was thought to be a bit larger proportion. Thus, it is necessary to improve the assembly process of the assemble?able cold?storage incubator. In addition, the commodity and nutritional value of pleurotus ostreatus are rarely reduced during cold storage. When the values after 60 h were compared with those at the beginning, the sensory evaluation scores, the soluble?solids content, the soluble?protein content and the vitamin C content had dropped by 3. 53％, 5. 9％, 4. 2％ and 9. 96％ respectively.关键词
