Abstract: |
By simulating the environment of imported soybean in sea transportation,combining the principle of damage index in biological survey statistics and using the average level of heat-damage as index,the effects of storage temperature and moisture content of imported soybean on its heat-damage were studied. The results showed that the moisture content and storage temperature were the directly influencing factors for the heat-damage of imported soybean. After being stored at 30,40,50[KG-*8]℃and 55[KG-*8]℃ for 28 d, the heat-damage process of soybean with moisture content less than 13% was slow,and the average level of heat-damage of the test samples did not reach the level of the heat-damaged kernel. Under the conditions of moisture content below 13% and temperature lower than 55℃,the degree and process of heat-damage of soybean were low in short-term storage. The broken soybean was much easier to cause heat-damage than the complete soybean,and its heat-damage degree was higher. Heat-damage was more likely to occur in Brazil soybean than in the USA and Argentina soybeans,and the occurance degree was higher. |
