该文研究了市售4种一级大豆油的部分理化指标、脂肪酸组成、甘三酯组成、甘一酯、甘二酯以及甾醇含量对其低温下抗冻性的影响。通过自制实验装置对大豆油进行冷冻试验和对大豆油固体脂肪含量的测定结果表明，脂肪酸组成、甘三酯组成、酸值、碘值、过氧化值、甘一酯含量对4种一级大豆油的抗冻性没有直接影响，而甘二酯的含量对一级大豆油抗冻性有一定影响。
該文研究瞭市售4種一級大豆油的部分理化指標、脂肪痠組成、甘三酯組成、甘一酯、甘二酯以及甾醇含量對其低溫下抗凍性的影響。通過自製實驗裝置對大豆油進行冷凍試驗和對大豆油固體脂肪含量的測定結果錶明，脂肪痠組成、甘三酯組成、痠值、碘值、過氧化值、甘一酯含量對4種一級大豆油的抗凍性沒有直接影響，而甘二酯的含量對一級大豆油抗凍性有一定影響。

The influence of the composition of fatty acids and triglycerides,part of the chemical indictors and the content of monoglycerides,diglycerides and sterols of the first grade soybean oils to their freezing resistance were evaluated here. According to the freezing experiments carried by the self-made experimental facility and the determination of the solid fat content of soybean oils,the results indicated that,the composition of fatty acids and triglycerides,iodine value,acid value,peroxide value,and the content of monoglycerides,and sterols had no direct influence on the freezing resistance, whereas the content of diglycerides had a certain influence on the freezing resistance of the first grade soybean oil.
