Development of identification technology on food using fluorescence fingerprint

建立了一种基于荧光指纹图谱的芒果地理来源鉴别新方法。以2010年和2011年台湾、宫崎和冲绳的芒果为研究对象，采用典型判别分析方法，对两个不同民族或三个不同产地的芒果进行了分类。2010年数据”和2010 + 2011年数据”。验证样本的误分类率分别为3.2- 19.2%和7.7- 13.6%。我们发现，由于误分类率较低，FF更适合于皮肤而不是牙髓。因此，FF法可作为芒果地理起源的一种实用方法。

A new method using fluorescence fingerprint (FF) to determine the geographic origin of mangoes was developed. Mangoes harvested in 2010 and 2011 from Taiwan, Miyazaki and Okinawa were examined.Canonical discriminant analysis was applied to separate the two nationalities or three localities of geographic origin.This analysis was carried out for two datasets, i.e., data of 2010" and data of 2010 + 2011". The misclassification rates of validation samples were 3.2-19.2 % and 7.7-13.6 %, respectively. we found that because of lower misclassification rates, FF is more suitable for skin than pulp. It is suggested that FF can be a practicalmethod to determine geographic origin of mangoes.
