Analysis of Antifungal Agent on Surface of Imported Orange

Introduction

The transportation of agricultural products imported into Japan from overseas requires considerable time. In such a case, some agricultural products are sprayed with postharvest agricultural chemicals to prevent mold and decay in the transportation process after harvesting. As Japan prohibits the importation, use, and sale of food products in which undesignated postharvest agricultural chemicals have been used, a technology that makes it possible to conduct inspections to identify postharvest agricultural chemicals by a simple sample preparation and testing procedure can shorten the inspection time, and as a result, is expected to lead to a shorter transportation time. This article introduces an example of detection of an antifungal agent, which is used as a postharvest agricultural chemical, on the surface of an imported orange with simple sample preparation by using a DPiMS^TM-2020 direct probe ionization mass spectrometer and a biological sample plate.
