| 中文摘要: |
| 以棉籽油为原料，利用干法分提对其进行改性。考察了结晶温度、冷却速率、养晶时间及搅拌速率对棉籽固脂碘值、0℃固体脂肪含量（SFC）及固脂得率的影响。确定的最佳分提工艺条件为：结晶温度5℃，冷却速率2℃/h，养晶时间10 h，搅拌速率15 r/min。所得固脂的碘值（I）为91 g/100 g，0℃ SFC为31.6%，固脂得率为12.89%。 |
| 英文摘要: |
| Cottonseed oil was modified by dry fractionation.The effects of crystallization temperature， cooling rate， crystallization time and stirring rate on iodine value,solid fat content（SFC） at 0℃ and yield of cottonseed solid fat were discussed.The results showed that the optimal fractionation conditions were obtained as follows： crystallization temperature 5℃，cooling rate 2℃/h， crystallization time 10 h，stirring rate 15 r/min. Under these conditions，the iodine value and SFC at 0℃ of cottonseed solid fat were 91 gI/100 g and 31.6% respectively， and the yield of solid fat was 12.89%. |
