基于固相萃取的粮油产品前处理技术研究进展

Solid phase extraction based on sample preparation for grain,oilseed and their products

粮油是人类生存的必需品,提供了人体不可缺少的三大基本营养素。粮油质量安全是国家重视、消费者关心的热点问题,检测是保证粮油产品消费安全的重要抓手。固相萃取是从粮油样品中提取待测物的重要手段,萃取材料是决定提取分离效率的关键因素。本文主要综述了基于固相萃取的粮油产品前处理技术研究进展,讨论了不同材料的优势及不足,并对粮油产品检测中新型萃取材料发展趋势进行了展望。

Grain,oilseed and their products are important for human beings,which provide the three most essential nutrients.Their quality and safety are hot issues,which draws more attentions from governments and consumers.Thus their detection methods are important to ensure the safety.Among them,solid phase extraction(SPE)is one of the most scientific method to extract targets from samples,and the extraction material is the key factor to influence the efficiency of both extraction and separation.This review summarized the research progress of SPE based pretreatment methods for grain,oilseed and their products,analyzed the advantages and disadvantages of different materials,and prospected development trends of new extraction materials in analytical methods for grain,oilseed and their products.
