中文摘要:

      脂溶性维生素品种丰富、结构类似、极性不同、在食品基质中含量差异大; 化学稳定性差, 在光、氧、酸、碱等条件下易降解, 因此多目标物高效前处理、降低基体干扰等关键技术是脂溶性维生素准确定量面临的挑战。本文综述了近年来从不同乳制品中提取脂溶性维生素的研究进展, 主要介绍了液液萃取、固相萃取、分散液液微萃取、磁性固相微萃取、QuEChERS等传统及新型提取与净化技术在乳制品中脂溶性维生素前处理中的应用, 概述了多种前处理技术的特点, 分析了新型前处理技术在减缓维生素降解速度和减少基质效应方面的优势及其发展的局限性; 展望了不同形式的维生素同时提取的发展趋势以及现行国家标准方法前处理技术多样化的发展前景, 以期对复杂基质中痕量组分的提取提供借鉴意义。

英文摘要:

      Fat-soluble vitamins are rich in variety, similar in structure, different in polarity and different in content in food matrix. The chemical stability is poor, and it is easy to degrade under the conditions of light, oxygen, acid, alkali, etc.. Therefore, the key technologies such as efficient pretreatment of multi-target and reducing matrix interference are the challenges faced by the accurate quantification of fat-soluble vitamins. This paper reviewed the research progress of extracting fat-soluble vitamins from different dairy products in recent years, mainly introduced the application of traditional and new extraction and purification technologies such as liquid-liquid extraction, solid-phase extraction, dispersed liquid-liquid microextraction, magnetic solid-phase microextraction and QuEChERS in the pretreatment of fat-soluble vitamins in dairy products, summarized the characteristics of various pretreatment technologies, and analyzed the advantages and development limitations of new pretreatment technologies in slowing down vitamin degradation rate and reducing matrix effect, and prospected the development trend of simultaneous extraction of different forms of vitamins and the development prospect of diversified pretreatment technologies of current national standard methods, in order to provide reference for the extraction of trace components in complex matrix.
