中文摘要: |
食品中的甲醛问题引起了人们的高度重视, 检测食品中的甲醛至关重要。食品中的甲醛主要来源于食品自身代谢合成、人为添加和环境污染。甲醛的分析方法包括样品前处理方法和甲醛检测方法。根据不同的食品种类, 需要选择合适的样品前处理方法, 具体方法包括: 浸泡法、蒸馏法、超声法和蛋白沉淀法。甲醛检测方法分为常规检测方法和快速检测方法。常规检测方法主要有分光光度法和色谱法。分光光度法包括乙酰丙酮法、变色酸法、AHMT法、间苯三酚法和盐酸苯肼法。目前甲醛快速检测方法成为了研究热点, 示波极谱法、试纸法、生物传感器法等快速检测方法得到快速发展。 |
英文摘要: |
The problem of formaldehyde in foods attaches great importance of the people, and the determination of formaldehyde in foods is crucial. The origins of formaldehyde in foods come from the food metabolism of itself, artificial adding and environmental pollution. The analysis techniques of formaldehyde include sample pre-treatment methods and detection methods. According to the kinds of foods, the suitable pre-treatment methods should be chosen, including immersing method, steam method, protein precipitation method and ultrasonic method. There are 2 types of detection methods: routine detection methods and rapid detection methods. The routine detection methods include spectrophotometric method and chromatography. The spectrophotometric methods include acetylacetones method, chromotropic acid method, AHMT method, phloroglucine method and phenylhydrazine hydrochloride method. Now the rapid detection methods of formaldehyde are areas of research focus, which include oscillating polarography, test method, and the biosensor method. |
