This work evaluates the capacity of a potentiometric electronic tongue to differentiate between types of honey (orange blossom, rosemary, thyme, sunflower, winter savory and honeydew honey) according to their antioxidant level. The classical procedures used to evaluate the antioxidant potential of honey are inappropriate for in situ monitoring on reception of batches of raw honey in the packaging industry. They are also destructive, time-consuming and very tedious, requiring highly expert analysts and specialised equipment.
The electronic tongue system made with Ag, Ni, Co, Cu and Au was able to not only differentiate between types of honey but also to predict their total antioxidant capacity. The discrimination ability of the system was proved by means of a fuzzy ARTMAP type ANN, with 100% classification success. A prediction multiple linear regression model showed that the best correlation coefficient was for antioxidant activity (0.9666), then for electrical conductivity (0.8959) and to a lesser extent for a , moisture and colour.
The proposed measurement system could be a quick, easy option for the honey packaging sector to provide continuous in-line information about a characteristic as important as the antioxidant level. © 2016 Society of Chemical Industry.
本研究评估了电位型电子舌根据抗氧化水平区分不同类型蜂蜜（橙花蜜、迷迭香蜜、百里香蜜、向日葵蜜、冬香薄荷蜜和甘露蜜）的能力。用于评估蜂蜜抗氧化潜力的传统方法不适用于包装行业对批量生蜂蜜收货时的现场监测。这些方法还具有破坏性、耗时且非常繁琐，需要高度专业的分析人员和专门设备。
由银、镍、钴、铜和金制成的电子舌系统不仅能够区分不同类型的蜂蜜，还能够预测其总抗氧化能力。通过模糊ARTMAP型人工神经网络证明了该系统的辨别能力，分类成功率达100%。预测多元线性回归模型表明，最佳相关系数是抗氧化活性（0.9666），其次是电导率（0.8959），而对酸度、水分和颜色的相关系数较小。
所提出的测量系统对于蜂蜜包装行业来说可能是一种快速、简便的选择，可用于提供有关抗氧化水平这一重要特性的连续在线信息。©2016化学工业协会。
