中文摘要:

      食品接触材料在加工过程中会加入一些抗氧剂, 以延缓材料的老化。但抗氧剂在与食品接触的过程中会迁移进入食品中, 危害消费者的身体健康。因此建立一种快速准确地检测食品接触材料中的抗氧剂含量的方法是很有必要的。本文对国内外抗氧剂检测技术进行综述, 包括样品前处理和分析检测方法, 目前主要采用超声波辅助提取法、超临界流体萃取法、微波辅助萃取法、固相萃取法、快速溶剂萃取法进行样品前处理, 红外光谱法、紫外光谱法、色谱法进行食品接触材料中抗氧剂含量的定量检测, 以期为食品接触材料中抗氧剂的检测方法研究提供参考。

英文摘要:

      Antioxidants are added into food contact materials in the processing, to slow the aging of materials. However, antioxidants will migrate into the food when they contacts with food, and then endanger the health of consumers. So it is necessary to establish a quick and accurate detection method for the determination of antioxidant content in food contact materials. This paper summarized the domestic and foreign detection methods of antioxidants including sample pretreatment methods and analytical technologies. The commonly used sample pretreatment methods included ultrasound assisted extraction, supercritical fluid extraction, microwave assisted extraction, solid-phase extraction and accelerated solvent extraction. The detection methods of antioxidants in food contact materials included infrared spectroscopy, ultraviolet spectrometry, and chromatography. It provided references for the researches on detection methods of antioxidants in food contact materials.
