摘要
食品产地溯源技术是有效实施食品原产地追溯、保护名优特产品的重要技术手段。国内外对植物源性食品产地判别的研究日益增加。植物源性食品的溯源对象已由葡萄酒、茶叶、咖啡、橄榄油、蜂蜜、果汁等扩展至小麦、土豆、番茄、大蒜、蘑菇等食品;其分析技术主要为矿物元素指纹分析、有机成分指纹分析、近红外光谱指纹分析和电子鼻;植物源性食品产地溯源在研究地域差异的基础上,已开始关注地域特征成因分析及品种、年际、加工工艺等对溯源指标的影响。但对于不同亚地区的食品来源区分还存在较大困难,溯源模型的稳定性研究仍旧缺乏。本文旨在为植物源性特色农产品和地理标志食品的产地溯源、确证及监管研究提供参考。
The technologies for tracing the geographical origins of food products are very important for effectively assessing the geographical origins and protecting specialty food products. An increasing amount of research has been dedicated to identifying the geographic origins of food products in China and abroad. The geographical traceability of plant-derived food products has been extended to wheat, potato, tomato, garlic and mushroom from wine, tea, coffee, olive oil, honey and fruit juice. The principal analytical techniques used include mineral element fingerprinting, organic compound fingerprinting, near infrared spectroscopic fingerprinting and electronic nose. Many researchers in related fields have begun to focus on the causes of the regional characteristics and the influences of variety, harvest year and food processing technologies on the traceability indexes of plant-derived food products from different geographical origins. However, it is difficult to differentiate the sub-regional characteristics of food products, and there is still a lack of research on the stability of traceability models. This review is expected to provide references for tracing, confirming and supervising the geographic origins of specialty plant-derived products and geographic indication products.
