【摘要】 [目的]探讨采用酸水解-自动索氏提取仪测定食品脂肪含量的方法。[方法]样品在酸水解仪中经盐酸水解后,置于索氏提取仪中用有机试剂提取脂肪,提取完毕后取出干燥称重即获得结果,并与国标法比较。[结果]操作条件经优化后,两种方法未见显著性差异。[结论]应用酸水解-自动索氏提取仪检测食品中脂肪的自动化程度高,适用范围广,操作简便,准确和环保。更多还原

【Abstract】 [Objective]To explore the method of adopting acid hydrolysis-automatic Soxhlet analysis instrument to measure fat content in food.[Methods] The samples were put in Soxhelt analysis instrument and extracted fat with organic reagent after they were hydrolyzed by hydrochloric acid in SoxCap, and then took out leavings, to dry them and to weigh them when the extraction was finished.And then the result was gotten.At last, the result was compared with the national standard method.[Results] The result by using instrument hads no significant difference from national standard method after conditions in operating were optimized.[Conclusion] Applying acid hydrolysis-automatic Soxhlet analysis instrument to measure fat content in food has high automation degree, wide application sphere, easy operation, high precision and environmental protection.更多还原
