稻米中矿物质元素的检测及其在产地溯源中的应用研究进展

Research progress on the detection of mineral elements in rice and the elements-based identification of rice geographical origin

稻米是我国的主要粮食之一,稻米的安全和品质越来越受到人们的关注。稻米中的矿物质元素特征不但关系到稻米的消费安全,同时也和稻米的品质密切相关。稻米中的矿物质元素特征和稻米的品质受到某些地理因素包括气候和土壤等的影响,因此各地的稻米具有不同的矿物质元素特征和地理标志特色。稻米中矿物质元素的分析检测以及其特征分析对于稻米的品质和产地溯源具有重要意义。近十多年来,有关稻米中矿物质元素的分析检测以及基于矿物质元素特征的稻米产地溯源技术得到越来越多的关注,在方法学上取得了显著的进步。本文主要针对近十多年来有关稻米粮食中主要矿物质元素的分析检测方法和基于矿物质元素的产地溯源方法的研究进展进行概述,以期为食品检测机构或食品安全研究或评估人员提供方法学上的参考。

Rice is one of the main grains in China,and thus,the safety and quality of rice has attracted increasing attention.The distribution characteristics of mineral elements in rice not only affect the consumption safety but also affect the quality of rice.In fact,the distribution characteristics of mineral elements in rice and the quality of rice are all influenced by certain geographical factors including climate,soil and so on.Therefore,rice samples from different regions have different distribution characteristics of mineral elements and different geographical indication characteristics.The detection and the stoichiometric analysis of mineral elements in rice are of great significance for tracing the geographical origin of rice and ensuring the quality of rice.In the past decade,the detection of mineral elements in rice and the origin tracing technology based on mineral element have received increasing attention,and notable progress has been made in the methodology.This paper summarized the progress on the detection of main mineral elements in rice and on the methods of tracing geographical origin of rice based on mineral elements over the past decade,in order to provide methodological reference for food testing institutions or food safety researchers or evaluators.
