Study On The Storage Temperature And Stacking Height On The Kexin1Potato Storage Losses And Effects Of Quality

This study used the Kexin1as material,which researched the hanges in thestorage quality of potato tubers in four different temperature(1℃、4℃、8℃and16℃)conditions and the stacking height, stacking position on the storage quality ofpotato during the storage.To seek the suitable storage temperature and stackingheight,packagingforms,for different uses of potato.In order to provide theoreticalbasis and scientific guidance on China’s hoard of potato, to lay the foundation forthe healthy development of the potato industry.the results showed:(1)Effects of different temperature on the storage of Kexin1potato nutritionqualityIn four different storage temperatures, changes in the quality of internal potatostarch content is larger, which, storage temperature the smallest decline; reducingsugar content increased at1℃,4℃,8℃storage temperature,1℃maximum risingdegree, and16℃decreased; protein content showed a downward, upward andthen downward trend in4different storage temperatures, drop extent is16℃>1℃>4℃>8℃.For potato starch processing and edible can be stored at4℃and for therequirements of high dry matter content, while requiring low reducing sugarcontent of French fries, potato chips, potato processing, can be stored at8℃.(2) Effects of different temperature on the storage of Kexin1potato enzyme activityDuring the period of storage, the amylase activity changed little, but in thelate storage period showed an upward trend, in which4℃storage temperatureamylase activity was the most stable, basically unchanged; polyphenol oxidasewere increased during storage period, change tendency of16℃>8℃>4℃>1℃.（3）The influence of different stacking height and stacking position of Kexin1potatoThe stacking layers of potato is not better as low as possible and we cancontrol the stacking height of potato to reduce the storage loss；The weight andmoisture loss during storage was positively correlated;We can determine theweight loss throught the decrease of the potato heap height.Different stackingposition has little effect on the storage loss.
