Studies on extraction of fumonisins from rice, cornbased foods and beans.

Different solvent mixtures were examined for the extraction of fumonisins from various naturally contaminated and spiked fools and feedstuffs. Most of the naturally contaminated samples were analysed using the extraction solvent mixtures methanolacetonitrile-water(25:25:50, solvent A) and methanol-water (75:25,solvent B; 80:20,solvent BB). Some were extracted with 0.1M sodium hydrogen phosphate-acetonitrile  (1:1, solvent C) and methanol-0.025 M borate buffer (3:1, solvent D). Solvent A gave slightly better extraction of fumonisins from naturally contaminated rough rice and white corn flour than solvent B,and better  extraction than solvents C and D. Solvent A was also a better sovent for fumonisins in naturally contaminated tortilla chips and infant cereals. Recovery of fumonisins from spiked corn meal, tortilla chips, corn flakes, various types of beans and infant cereals with solvent A and/or solvent B (or BB) was satisfactory. Recovery of fumonisins was very poor from spiked white rice but satisfactory   from other rice foods.
