Abstract
In this study, sodium tetraborate (Na₂B₄O₇) was used as an inhibitor to exploit the electron-withdrawing capability of boron atoms, it locks the activated lone pair electrons of hydroxyl oxygen and blocks the formation of the first intermediate, thereby inhibiting acyl migration. Under the optimized conditions of pH 6.0, temperature 60 °C, enzyme addition 0.02%, Na₂B₄O₇ addition 0.8%, and reaction time of 4 h, the phosphorus content in crude soybean oil was reduced to 12.1 mg/kg, while the FFA content increased to 1.05 g/100 g. Compared to conventional enzymatic degumming, the FFA content was reduced by 0.19 g/100 g, and the acyl migration rate was decreased by 17.0%. Liquid chromatography analysis confirmed that the addition of the inhibitor achieved moderate enzymatic degumming of crude soybean oil.
