Abstract:
This study investigated the impact of baking factors on fumonisin B (FB) levels in corn crisps using ultraperformance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). The results indicated that both free and total FBs decreased with an increase in baking time and temperature, while glucose addition facilitated this reduction. Total FBs reached the lowest value of 109.69 ng/g after 50 min of baking. Conversely, covert FBs increased with baking time but decreased with glucose addition at high temperatures. Additionally, the highest levels of hydrolyzed FBs (HFBs), N-(carboxymethyl) FB1, and N-(deoxy-d-fructos-1-yl) FB1 occurred 20 min before decomposing and were detected in corn crisps baked at 160 °C. Glucose addition accelerated the transformation between free and covert FBs. Furthermore, the inhibition of NCM FB1 accumulation was accompanied by the promotion of NDF FB1 accumulation during corn crisp processing. These findings provide insights into the effect of baking factors on FBs and suggest strategies for reducing FB contamination in corn crisps.
