中文摘要：在温带地区，玉米在食物链中使用的主要局限性，在于其种植期间受B系伏马菌素（FBs）的污染。由于在研磨后这种霉菌毒素的含量分布不均，本研究的目的就是比较FBs在两种工业干磨工艺，干法脱胶（DD）系统和回火脱萌（TD）系统所研磨的玉米不同组分中的分布。研究表明，在这些玉米组分中，粒径越大，FBs减少得越多。
外文摘要：In temperate areas, the main limitation to the use of maize in the food chain is its contamination by B-series fumonisins (FBs) during cultivation. Since the content of this group of mycotoxins may be distributed unevenly after milling, the aim of this study was to compare the distribution of FBs in maize fractions derived from two industrial dry-milling processes, that is, a dry-degermination (DD) system and a tempering-degermination (TD) system. Grain cleaning reduces FBs by about 42%. The germ of the two degermination processes showed a similar FB content of kernel after cleaning. Conversely, an animal feed flour resulted in a FB content that was two times higher than whole grain before cleaning. A significant FB reduction was observed in the milling fractions in both processes, with a higher reduction in the TD system than in the DD one. The average decontamination respect to uncleaned kernels in the DD process was 50%, 83% and 87%, for maize flour, break meal and pearl meal, respectively, while it was 78%, 88% and 94% in the TD process for small, medium and flaking grits, respectively. Among the milling fractions, the flaking grits with the highest particle size resulted in the highest FB reduction.
