| Abstract: |
| Quantitative detection device and method for nitrogen content in edible vegetable oil were briefly introduced. The saturated nitrogen content in different kinds of edible vegetable oils at 8-35?℃ could be determined by the detection device. Based on the data of saturated nitrogen content, the actual nitrogen content and filling nitrogen rate of different edible vegetable oils could be determined. The effect of temperature on nitrogen content in oil was studied, suggesting that the appropriate temperature of filling nitrogen was 15-20?℃, and the lowest filling nitrogen rate of the finished edible vegetable oil was 75% to avoid deformation of oil bottle during shelf life. These parameters could provide guidance for industrial production of edible vegetable oil. |
