| Abstract: |
| Heat-damage often occurs during sea transportation of imported soybeans, thus causing economic disputes. Aiming to provide a theoretical basis for the objective assessment of the degree of heat-damage of imported soybeans, the impact of heat-damaged soybeans on the crude fat content and crude oil yield was objectively analyzed by combining imported South American soybean testing data with the daily production reports of the factory. The results showed that the average crude fat content of 34 batches of imported South American soybeans before heat-damage was 20.53%, and the average crude fat content after heat-damage was 2076%; the data from the daily production reports of oil factories showed that the heat-damaged kernel rate of heat-damaged soybeans processed in the factories varied from 1.96% to 9017%, and that the curde oil yields of soybeans with different degrees of heat-damage fluctuated narrowly above and below 20% without any obvious difference. In conclusion, there is no direct causal relationship between heat-damaged soybeans and crude soybean oil yield. |
