| Research Abstract |
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 practical
method to determine geographic origin of mangoes.
