| 中文摘要: |
| 以无水脱皂工艺和传统脱皂工艺生产的中和大豆油为原料，经过脱色和脱臭，制备了脱色大豆油和脱臭大豆油。比较了无水脱皂工艺和传统脱皂工艺制备的脱色大豆油和脱臭大豆油的部分指标，同时对精炼大豆油进行了返酸、返色实验和180 ℃高温劣化实验。结果表明：两种脱皂工艺的脱色大豆油和脱臭大豆油的理化指标并无明显差异；无水脱皂工艺的精炼大豆油Δ 酸价和ΔR均略高于传统脱皂工艺的，无水脱皂工艺的精炼大豆油高温劣化速度比传统脱皂工艺的快。 |
| 英文摘要: |
| With neutralized soybean oils prepared by water-free de-soaping process and traditional de-soaping process as raw materials, after bleaching and deodorization, the physicochemical indexes of bleached soybean oil and deodorized soybean oil were compared. In addition, the acid and color reversion and the high temperature deterioration （at 180 ℃） experiments of the deodorized soybean oil were carried out. The results showed that the physicochemical indexes of bleached soybean oil and deodorized soybean oil prepared by water-free de-soaping process and traditional de-soaping process had no significant differences. The ΔAV and ΔR of the refined soybean oil with the water-free de-soaping process were slightly higher than that of the traditional de-soaping process.The refined soybean oil with the water-free de-soaping process deteriorated faster than the refined soybean oil with the traditional de-soaping process. |
