为确定低场核磁共振技术是否能用于山桐子含油率的快速检测,达到准确高效、节约检测成本的目的.通过对比低场核磁共振检测法与索氏抽提法在测定山桐子含油率的差异,并考察低场核磁共振检测法的精密度和稳定性.结果表明,低场核磁共振检测法定标曲线的拟合相关系数大于0.9999,两种检测方法测定结果的绝对偏差范围在0.04％～1.40％之间,相对偏差范围在0.15％～9.86％之间,低场核磁共振检测法的精密度和稳定性良好.低场核磁共振技术可应用于山桐子含油率的检测,具有准确、快速、高效的特点.
Rapid Detection of Oil Content in Idesia polycarpa Based on Low Field Nuclear Magnetic Resonance
In order to determine the feasibility of using low-field nuclear magnetic resonance(NMR)technology for the rapid detection of oil content in Idesia polycarpa seeds,with the aim of achieving accurate and efficient results while reducing costs.The results obtained from the low-field NMR detection method were analyzed and compared with those of the soxhlet extraction method for determining the oil content in Idesia polycarpa seeds.The precision and stability of the low-field NMR detection method were also evaluated.The results indicated that the fitting correlation coefficient of the calibration curve for low-field nuclear magnetic resonance detection is greater than 0.999 9,and the absolute deviation range of the results of the two detection methods was between 0.04％and 1.40％,and the relative deviation range was between 0.15％and 9.86％.Therefore,this method exhibits good precision and stability.In conclusion,low-field NMR technology can be effectively applied in the detection of oil content in Idesia polycarpa seeds,offering the advantages of accuracy,speed,and efficiency.
