Fate of fumonisin B1 in corn kernel steeping water containing SO2
1999
Pujol, R. | Torres, M. | Sanchis, V. | Canela, R.
Six 100 ppm fumonisin B1 (FB1) solutions were prepared by dissolving pure standard in six different solvents containing SO2. Two of the solvents contained 0.2 or 0.4% SO2 in distilled water. The other four solvents were obtained by steeping corn kernels at 60 degrees C in a 0.2% SO2 aqueous solution for 6, 12, 24, or 48 h. After the addition of FB1, all solutions were maintained at 60 degrees C for 7 days. Fumonisin B1 content in each solution was determined in triplicate by HPLC. Steeping corn kernels in 0.2% solution at 60 degrees C for 6 h seems to be the most effective treatment to decrease the amount of FB1.
