摘要
油脂密度是油脂大宗贸易中需检测的一个重要指标,本实验对国标GB/T 5526-85《植物油脂检验比重测定法》和现代仪器自动密度仪法测定油脂密度进行了比较并讨论了计算净含量时的空气质量问题,结果表明采用自动密度仪法测得的油脂密度和国标法相吻合,并且自动密度仪法更简便快捷、结果重现性好,精确度高;计算净含量时由密度仪测得的密度要减去空气密度。
The oil density is an important indicator that is detected in significant trade.In this study,the national standard GB/T 5526-85 ＂the test of vegetable oils pycnometer method＂ and the automatic density meter method are compared and air quality are discussed in oil net mass.The results showed that the values of oil densities by pycnometer method were in accordance with those by automatic density meter method.But the automatic density meter method was more convenient with higher reproducibility and precision than the pycnometer method.The air density should be deducted by oil density detected by Automatic Density Meter method when calculating oil net msss.
