The distribution of fumonisins (FBs: FB1 and FB2) in the corn-milling process and in corn-based products, as well as daily intake estimates for the Brazilian population were evaluated. Among corn fractions samples, corn meal had the highest mean concentration of FB1 (1305 µg kg(-1)) and FB2 (651 µg kg(-1)) and a distribution factors of 452% and 256% in relation to corn grain, respectively. On the other hand, the distribution factor of FB1 and FB2 in corn flour was found to be 144% and 88% respectively, which demonstrates that fumonisins in this fraction were reduced compared with corn grain. As a result, almost half the corn meal samples (47%) would be non-compliant with future Brazilian regulation (2017) for fumonisins. However, corn-based products, such as corn flakes and popcorn, were in compliance with the regulation. The average probable daily intake and maximum probable daily intake of fumonisins estimated for the Santa Catarina state (Brazil) population were below the provisional maximum tolerable daily intake of 2 µg kg(-1) body weight day(-1) for all corn samples. Despite this, the adoption of practices to control the occurrence of fumonisins should be applied to the corn-milling fractions that may contain a higher concentration of this toxin, such as corn meal, often used for animal feed in Brazil.
评估了伏马毒素（FBs：FB1和FB2）在玉米加工过程及玉米制品中的分布情况，以及巴西人群的每日摄入量估计值。在玉米各组分样品中，玉米粉中FB1的平均浓度最高（1305 μg kg⁻¹），FB2的平均浓度也最高（651 μg kg⁻¹），相对于玉米粒，其分布因子分别为452%和256%。另一方面，发现玉米粉中FB1和FB2的分布因子分别为144%和88%，这表明该组分中的伏马毒素含量相对于玉米粒有所降低。因此，几乎一半的玉米粉样品（47%）不符合巴西未来（2017年）对伏马毒素的规定。然而，玉米片和爆米花等玉米制品符合该规定。对巴西圣卡塔琳娜州人群估计的伏马毒素平均每日可能摄入量和最大每日可能摄入量，对于所有玉米样品均低于2 μg kg⁻¹体重·日⁻¹的暂定每日最大耐受摄入量。尽管如此，对于可能含有较高浓度这种毒素的玉米加工组分，如在巴西常作为动物饲料的玉米粉，应采用控制伏马毒素产生的措施。
