电子鼻主要用于食品和饮料行业的不同应用：识别、定量、质量控制。在每个应用程序中。该仪器的主要目标是能够区分不同样品的不同感官特性。这些属性可以是质量、来源、缺陷、污染物浓度。该仪器的一个有用之处是，当它在分析产品上诱导出与人类感官面板诱导的结构相同的结构时，该面板允许仪器测量感觉属性。在这种情况下，数学方法被用来利用这种相关性，以使感官面板的能力保持一致。感官面板的知识和能力被转移到生产车间进行常规分析。在本文中，介绍了电子鼻用于确定牛奶保质期的结果。为此，牛奶被储存在环境温度和5摄氏度的恒温下，并在不同的时间用电子鼻对每一种储存的牛奶样品进行分析。这里提出的数学方法将提出一些有趣的时间事件，在关于牛奶货架期的文献中找到，与牛奶进化或陈化中的重要事件相对应。©2004爱思唯尔B.V.保留所有权利。
Electronic Nose is mostly used for different applications in food and beverage industries: identification, quantification, quality control. In each application. the principal goal is that this instrument could discriminate different organoleptic properties of different samples. Those properties could be qualities, origins, defects, concentration of pollutants.One of the usefulness of this instrument is when it induces, on the analyzed products, the same structure as the one induced by a human sensory panel allowing instrumental measurement of sensory properties. In this case, mathematical methods are used to exploit this correlation in order to bring in line the sensory panel capabilities. Sensory panel knowledge and capabilities are transferred to the production shop floor for routine analysis.In this paper, one presents the results of Electronic Nose used to determine the shelf life of milk. To do this, milk was stored at ambient temperature and at constant temperature of 5 ° C. Samples of each of the stored milk have been analyzed by electronic nose at different times. The mathematical method presented here will suggest some interesting time-events, found in the literature on milk shelf life, that correspond to significant ones in the milk evolution or aging. © 2004 Elsevier B.V.
