基于电子鼻和电子舌技术对市售羊奶粉的鉴定及检测

Identification and Quality Detection of Commercial Goat Milk Powder Using Electronic Nose and Electronic Tongue

为鉴别及检测不同地区市售羊奶粉的品质,用电子鼻和电子舌技术对陕西地区和非陕西地区(包含国内非陕西地区和国外地区)的纯羊奶粉和配方羊奶粉共35种市售羊奶粉进行分类与检测,探究不同产地、不同配方之间羊奶粉的差异,对羊奶粉品质进行分析判别。结果表明,电子鼻技术可实现对纯羊奶粉和配方羊奶粉、国内地区与国外地区纯羊奶粉的有效区分;电子舌技术可实现对纯羊奶粉和配方羊奶粉、陕西地区和国内非陕西地区纯羊奶粉的有效区分。因此采用电子鼻和电子舌技术对不同产地来源、不同配方种类的羊奶粉进行分析,并对多种奶粉进行质量评估检测,可为市售羊奶粉质量的快速准确评估及其规范化生产提供理论依据。

To identify and test the quality of commercially available goat milk powder(pure and formulated)from different regions(Shaanxi,domestic non-Shaanxi regions and foreign regions),electronic nose and electronic tongue technology were used to analyze and discriminate 35 such samples from these regions with different formulations.The analysis results showed that electronic nose was able to achieve effective differentiation between pure and formulated goat milk powder,as well as between pure goat milk powder from domestic and foreign regions.Additionally,the electronic tongue technology can achieve effective differentiation between pure and formulated goat milk powder,and between pure goat milk powder from Shaanxi and domestic non-Shaanxi regions.Therefore,electronic nose and electronic tongue can be used to analyze goat milk powder from different origins and different formulations,to identify its origin and evaluate the quality.It is believed that this study provides a theoretical basis for a rapid and accurate evaluation of the quality of goat milk powder and its standardized production.
