Fumonisin monitoring in Thai red cargo rice by reversed-phase high-performance liquid chromatography with electrospray ionization ion trap mass spectrometry

Tansakul N., . and Limsuwan S., . and Trongvanichnam K., . Fumonisin monitoring in Thai red cargo rice by reversed-phase high-performance liquid chromatography with electrospray ionization ion trap mass spectrometry. pp. 1561-1566. ISSN 2231-7546

The occurrence of fumonisins in red cargo rice from Thailand was studied by high-performance liquid chromatography with electrospray ionization ion trap mass spectrometry (LC-ESI-MS/MS). A quantification method for fumonisin B1 (FB1) was developed and the chromatogram of fumonisin B2 (FB2) was observed. The present method provides a sensitive detection limit at 1.0 ng g-1. The limit of quantification was 5.0 ng g-1. The recovery rate showed high yield of accuracy at 110.113.3 89.311.1 and 91.94.6 after fortification (n5) at 50 100 and 500 ng g-1 respectively. Of the fifty eight samples from the retail markets two samples were found to be naturally contaminated with FB1 at a trace level (lower than 5.0 ng g-1). None of FB2 was found in any of the samples. This is the first report about the natural occurrence of FB in red cargo rice from Thai market.

Abstract

The occurrence of fumonisins in red cargo rice from Thailand was studied by high-performance liquid chromatography with electrospray ionization ion trap mass spectrometry (LC-ESI-MS/MS). A quantification method for fumonisin B1 (FB1) was developed and the chromatogram of fumonisin B2 (FB2) was observed. The present method provides a sensitive detection limit at 1.0 ng g-1. The limit of quantification was 5.0 ng g-1. The recovery rate showed high yield of accuracy at 110.113.3 89.311.1 and 91.94.6 after fortification (n5) at 50 100 and 500 ng g-1 respectively. Of the fifty eight samples from the retail markets two samples were found to be naturally contaminated with FB1 at a trace level (lower than 5.0 ng g-1). None of FB2 was found in any of the samples. This is the first report about the natural occurrence of FB in red cargo rice from Thai market.
