Abstract

The fate of Fusarium mycotoxin nivalenol during milling of a Japanese wheat cultivar was investigated. Grain samples with two distinct nivalenol levels were test-milled to produce six fl our fractions (Breaking flours: 1B, 2B, and 3B, Middling flours: 1M, 2M, and 3M) and two outer layer fractions (bran and shorts). Patent flour for human consumption was made from 1B, 1M, 2B, and 2M, while low-grade flour was made from 3B and 3M. These four samples; Patent flour, low-grade flour, bran and shorts were analyzed for the content of nivalenol by HPLC-UV. Two samples showed similar patterns of nivalenol distribution in milling fractions.

镰孢菌严重侵染日本软冬小麦籽粒碾磨组分中雪腐镰刀菌醇的分布
研究了一种日本小麦品种制粉过程中镰刀菌毒素雪腐镰刀菌醇的去向。具有两种不同雪腐烯醇水平的谷物样品进行了测试研磨,以生产6个层分(破碎粉:1B, 2B和3B,中粉:1M, 2M和3M)和两个外层分(麸皮和短粒)。人类食用专利面粉由1B、1M、2B和2M制成,低档面粉由3B和3M制成。这四个样本;采用高效液相色谱-紫外分光光度法测定了专利面粉、普通面粉、麸皮和面粉中雪缬醇的含量。两种样品在碾磨馏分中显示出相似的雪缬醇分布模式。
