摘要
食品产地溯源和确证是食品安全监管的重要内容,也是地域或特色食品产业可持续发展的重要保障。本文旨在探析食品产地溯源及确证技术原理和方法,推动食品溯源及确证技术支撑体系的研究与应用。作者通过对食品产地溯源及确证技术原理和应用分析,总结出食品产地溯源及确证技术研究和应用的基本思路、步骤和方法。食品产地溯源及确证技术的基本研究思路为:分析表征地域差异的特性、建立判别模型、验证判别模型、建立数据库、判别和举证分析;应用的基本方法为化学成分分析和多元数理统计方法,如方差分析、多重比较分析、聚类分析、主成分分析、判别分析等化学计量学方法。食品产地溯源及确证技术是基于能够表征食品地域特征的化学分析方法和多元数理统计方法建立的一套甄别食品地域来源的技术体系。
The food geographical origin traceability and authenticity is very important for food safety surveillance, and it is also important for protecting sustainable development of geographical or special food. The aim of the study is to explore the principle and method of food geographical origin traceability and authenticity, and to promote the research and application of food traceability and authenticity technology. The basic thought, step and method of food geographical origin traceability and authenticity were summarized by analyzing principle and application. The basic thought of food geographical origin traceability and authenticity technology is analyzing the difference in characteristics of geographical origin, building the discriminant mode, testing the discriminant mode, building the database, and discriminant and testing analysis. The basic method is the chemometrics which synthesizing the chemical composition analysis and Multivariate statistics such as analysis of variance, multiple comparison analysis, cluster analysis, principal component analysis, discriminant analysis and so on. The food geographical origin traceability and authenticity is a technology system for distinguishing the food geographical origin based on chemical composition analysis and multivariate statistics.
