中文摘要:

为促进我国小麦麸皮资源的加工转化，收集了我国9个小麦主产省12家大型面粉加工企业的商品小麦麸皮样品，对蛋白质、淀粉、膳食纤维、戊聚糖、脂肪、灰分等主要营养成分以及重金属、农药残留、真菌毒素等安全危害因素进行了分析与比较。结果表明，不同来源的小麦麸皮在营养组成上存在一定差异，其中以总淀粉含量差异最大（CV：35.31%），粗蛋白含量差异最小（CV：5.16%）；麸皮蛋白的氨基酸组成中，以蛋氨酸含量差异最为显著（CV：20.06%）。质量安全指标中，重金属含量均未超标，农药残留未检出；真菌毒素，仅河北邯郸一家麸皮样品中的脱氧雪腐镰刀菌烯醇（DON）含量超出限量范围。对比所选取12个样品的品质表现，收集于河北邢台、山东滨州和北京的样品，戊聚糖、蛋白质含量较高，总淀粉含量较低，卫生状况良好，可用于小麦麸皮的深加工与综合利用。

英文摘要:

In order to expedite the processing and converting procedure of Chinese wheat bran resources, the edible nutritional properties and safety quality of 12 wheat bran samples from nine major wheat production areas in China were investigated. The contents of nutritional constituents and hazard factors were analyzed and compared among these samples, including crude protein, total starch, dietary fiber, pentosan, crude fat, ash, heavy metal residue, pesticide residue and mycotoxins. The results showed that there were differences in nutritional characteristic indexes among different samples, the contents of total starch and crude protein had the largest and minimum variation and the variation coefficient was 35.31% and 5.16%, respectively. Amino acid components analysis of crude protein showed methionine had the largest variations and the variation coefficient reached to 20.06%. In the safety quality indexes, the contents of heavy metal residue were lower than the limit range, and pesticide residues were not detected. In the mycotoxin indexs, the DON content of one sample from Hebei Handan flourmill exceeded the limit range. Contrasting the nutritional and sanitary quality of the 12 wheat bran samples, three superior samples were selected for further processing and comprehensive utilization of wheat bran, and these samples came from Xingtai of Hebei province, Binzhou of Shandong province and Beijing, respectively.
