摘　　要：以掺假牛乳样品为检测对象,利用电子舌结合主成分分析法进行研究,旨在寻求一种能有效监控牛乳品质的快速检测方法。对几种常见的掺假(掺入水、食盐、蔗糖、尿素、大豆油)牛乳样品、复原乳以及纯牛乳样品进行检测和评价。试验结果表明:电子舌可以很好地区分纯牛乳和掺入不同物质的牛乳样品,纯牛乳、纯鲜牛乳、复原乳及其混合乳样品得到有效辨识,同时各种掺假牛乳样品随掺入物质的比例在主成分得分图中呈规律性分布。电子舌可用于掺假牛乳的快速检测。在建立典型标准样品数据库的前提下电子舌可有效监控牛乳品质,其在乳制品的质量控制及评价中具有较大的应用潜力。To seek a method of rapid monitoring of milk quality,adulterated milk were analyzed by the electronic tongue coupled with principal component analysis（PCA）.Milk samples adulterated with water,NaCl,sucrose,urea or bean oil,reconstituted milk and UHT sterilized milk samples were analyzed.The experimental results showed that electronic tongue could discriminate not only between UHT sterilized milk and different kinds of adulterated milk,but also UHT sterilized milk,pasteurized milk,reconstituted milk and their mixed milk.The application of electronic tongue in adulterated milk with different additive proportions showed the similar result,too.The electronic tongue could be used for rapid detection of adulterated milk,and also for effective monitoring of milk quality with a database of typical standard samples.The electronic tongue shows a greater potential in the evaluation of dairy products quality.
