| Abstract: |
| 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. |
