| 中文摘要: |
| 以一级压榨葵花籽油为基料油，添加分子蒸馏单甘酯与谷维素-谷甾醇制备复合凝胶。探讨了凝胶剂添加量、凝胶剂比例、加热温度、加热时间和冷却温度对复合凝胶析油率的影响。结果表明：在谷维素-谷甾醇与分子蒸馏单甘酯质量比为6∶?4，添加量为9%，加热温度为90?℃，加热时间为20 min，冷却温度为10?℃条件下，复合凝胶析油率为0.61%，具有较好的油结合能力、较低的熔点和合适的硬度，且不含反式脂肪酸，饱和脂肪酸含量仅为14.27％，低于传统专用油脂中饱和脂肪酸含量。 |
| 英文摘要: |
| The compound gel was produced with monoglyceride and oryzanol-sitosterol as organogelators and first grade pressed sunflower seed oil as base oil. The effects of dosage of organogelator, mass ratio of oryzanol-sitosterol to monoglyceride, heating temperature, heating time and cooling temperature on the oil precipitation rate of compound gel were discussed. The results showed that the optimal preparation conditions were obtained as follows: mass ratio of oryzanol-sitosterol to monoglyceride 6∶?4, dosage of organogelator 9%, heating temperature 90?℃, heating time 20 min, cooling temperature 10?℃. Under the optimal conditions, the oil precipitation rate of compound gel was 0.61%with better oil binding capacity, lower melting point and suitable hardness, no trans fatty acid was detected, and content of saturated fatty acids was only 14.27%, which was lower than that of traditional special oils and fats. |
