Abstract

The production and consumption of home-brewed Xhosa maize beer is a widespread traditional practice in the former Transkei region of South Africa. HPLC determination of fumonisins B1 (FB1), B2 (FB2), and B3 (FB3) in maize beer samples collected in two magisterial areas, Centane and Bizana, showed a wide range of levels. All samples were positive for FB(1), with a mean level of 281 +/- 262 ng/mL and a range from 38 to 1066 ng/mL. Total fumonisins (FB1 + FB2 + FB3) ranged from 43 to 1329 ng/mL, with a mean of 369 +/- 345 ng/mL. Data on the consumption of home-brewed beer are not available. On the basis of published data for the consumption of commercial beer in South Africa, the fumonisin exposure in these districts among the consumers of maize beer was found to be well above the provisional maximum tolerable daily intake of 2 mug/kg of body weight/day set by the Joint FAO/WHO Expert Committee on Food Additives.

摘要

在南非前特兰斯凯地区，自酿科萨玉米啤酒的生产和消费是一种广泛存在的传统习俗。采用高效液相色谱法（HPLC）对在两个行政区（森泰恩和比扎纳）采集的玉米啤酒样品中的伏马毒素B1（FB1）、B2（FB2）和B3（FB3）进行测定，结果显示其含量范围很广。所有样品的FB1均呈阳性，平均含量为281±262纳克/毫升，范围在38至1066纳克/毫升之间。伏马毒素总量（FB1 + FB2 + FB3）在43至1329纳克/毫升之间，平均为369±345纳克/毫升。关于自酿啤酒消费量的数据尚无可用信息。根据南非商业啤酒消费量的已发表数据，发现这些地区饮用玉米啤酒的消费者中伏马毒素的暴露量远高于联合国粮食及农业组织/世界卫生组织食品添加剂联合专家委员会设定的2微克/千克体重/天的暂定每日最大耐受摄入量。
