The effects of processing for two types of Asian noodles production (yellow alkaline and instant) on DON levels were investigated. Deoxynivalenol (DON) level at each step of processing was determined using high performance liquid chromatography (HPLC) with a PDA (photodiode array) detector at 218 nm. An acetonitrile: water (17:83 v/v) mixture was used as mobile phase and a MycosepTM #225 column as clean-up method. Significant reductions of the initial DON levels were found, 43.2% and 66.6% in yellow alkaline and instant noodles, respectively. The presence of alkaline salt as an ingredient appeared to be the primary factor influencing the extent of reduction in the two types of noodles. The data indicated that significant reduction of DON have occurred during cooking and frying of both yellow alkaline and instant noodles, respectively. The mechanism of reduction due to cooking is probably a leaching of DON out of the noodle into the cooking medium.
► The present study was designed to determine the effect of process steps on DON. ► The yellow alkaline and instant noodles have been prepared and DON contents were measured at each step of processing. ► Significant reductions of the initial DON levels were found, 43.2% and 55.0% in yellow alkaline and instant noodles, respectively. ► The mechanism of reduction due to cooking is probably a leaching of DON out of the noodle into the cooking medium whereas in instant noodle reduction is due to heat degradation of DON under alkaline condition.
