| 中文摘要: |
| 对大豆毛油中非水合磷含量的传统测定方法进行优化，用超声波法代替传统水浴加热法进行前处理，确定最佳条件，并将两种方法测定的结果进行比较，确定实验的可行性。结果表明，采用超声波法测定大豆毛油中非水合磷含量的最佳条件为超声温度85 ℃，超声时间2 h，超声功率300 W。采用超声波法和水浴加热法测得的同一大豆毛油样品中非水合磷含量的相对偏差满足国标允许误差要求，因此超声波法可以用来测定大豆毛油非水合磷含量。 |
| 英文摘要: |
| The traditional method for determination of non-hydrated phosphorus content in crude soybean oil was optimized. Also the crude soybean oil was pretreated using ultrasound method instead of traditional water bath heating method, and the optimal conditions were determined. Also the results of the two methods were compared to determine the feasibility of the experiment. The results showed that the optimal conditions for determination of non-hydrated phosphorus content by ultrasound method were obtained as follows: ultrasonic temperature 85 ℃, ultrasonic time 2 h and ultrasonic power 300 W. The relative deviation of non-hydrated phosphorus content in the same crude soybean oil sample measured by ultrasound method and traditional water bath heating method met the requirement of the national standard, so the ultrasound method could be used to determine non-hydrated phosphorus content in crude soybean oil. |
