| 中文摘要: |
| 进口大豆在海上运输期间常发生热损，从而引起经济纠纷。旨在为客观评估进口大豆热损程度提供理论依据，以进口南美大豆检测数据结合工厂加工的日报数据，客观分析了热损大豆对粗脂肪含量和原油得率的影响。结果表明：34批次进口南美大豆热损前粗脂肪含量平均值为20.53%，热损后粗脂肪含量平均值为20.76%；油脂厂生产日报数据表明，工厂加工热损大豆的热损伤粒率在1.96%~90.17%之间变化，不同热损程度的大豆的原油得率在20%上下窄幅波动，无明显差异。综上，热损大豆与大豆原油得率无直接关系。 |
| 英文摘要: |
| 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. |
