摘要
研究以食品风味为内容的分类分析和质量鉴别。应用多元组合型金属氧化膜感测器FOX3000 Electronic NoseSystem对59种茶叶、5种咖啡等嗜好性饮料进行“非破坏性”检测,将获得的感测数据应用主成分分析和判别分析方法进行茶叶样品分类识别,5种咖啡采用湿度和温度不同贮藏处理后再经检测,对其品质质量变化对比分析。分析结果显示不仅可以进行茶业类别区分,也可以区分产地、贮藏条件等与茶叶、咖啡质量有关联的品质影响因素。金属氧化膜传感器除在应用于食品风味类型的识别,还能够进一步推广应用于具有风味表现的食品质量鉴别与识别。
Study on classification of food flavor and discrimination food quality characteristic according to volatile compounds.Multianalysis of different metal oxide sensors, which is FOX3000 Electronic Nose System (Alpha M.O.S, France), to test forflavor of 59 kinds of tea and 5 kinds of coffee with “no-breakage” method was made use, and then carried out principlecomponent analysis (PCA) and discriminant function analysis (DFA). Coffee were experimented the change of quality afterstored for 10 days in condition of different humidity and temperature. Analyzing the result manifestation can adapt for not onlythe type of flavor of tea, but also can applied to analysis of effect factor related food qualities such as producing area, storecondition and so on. The metals oxide sensors can still further expand to apply to discriminate with identify in the food qualitythat have the aroma performance.
