食品中无机元素分析方法研究进展

食品中所含的无机元素,对人体的营养健康和摄入安全有至关重要的作用,研究和分析食品中的无机元素,有利于评价食品的营养价值,规避有毒有害食品;了解食品被污染的情况和程度,以便查清和控制污染源;也有利于指导营养强化食品的生产和开发及食品加工工艺的改进和食品质量的提高。因此,在食品生产过程都需要对无机元素含量进行监控和检测。本文综述了目前国内外食品中无机元素分析的主要方法及其特点和质量控制水平,既包含了传统的化学法、物理法,也涵盖了近些年才兴起的纳米技术法、生物技术法等,并列举了这些分析检测方法在近年来的实际应用,阐明了食品中无机元素分析方法的研究发展趋势,旨在为食品中无机元素分析检测研究者和从业者提供一定参考。

Advances in the analysis methods of inorganic elements in foods

Inorganic elements in food are very important to human body both on nutrition and health safety. The study and analysis of inorganic elements in food can help to evaluate the nutritional value of food and avoid toxic and harmful foods, and understand the situation and extent of food contamination in order to identify and control pollution sources. It is also beneficial to guide the production and development of fortified foods and to improve food processing technology and food quality. Therefore, the content of inorganic elements should be monitored and detected in the food production process. In order to provide a reference for the analysis of inorganic elements in food, the main methods and characteristics of inorganic elements analysis in food and its quality control at home and abroad were reviewed, and the development trend of inorganic elements analysis methods in food were clarified, including traditional chemical and physical methods, as well as covered nanotechnology and biotechnology in recent years. The practical application of these analytical methods in recent years was enumerated.
