轻剥皮和筛分工艺对小麦理化及卫生品质的影响

Effect of light debranning and screening processes on the physicochemical and hygienic quality of wheat

为探究轻剥皮和筛分工艺对小麦籽粒的清理效果,以面粉厂的实际生产车间为实验基础,选用轻剥皮工艺对应的双轴搓擦机和筛分工艺对应的组合清理筛,对经过重力分级去石机分选出的重质小麦进行清理。通过测定小麦的灰分、粗蛋白、脱氧雪腐镰刀菌烯醇和阿拉伯木聚糖含量等指标,分析轻剥皮和筛分工艺对小麦理化及卫生品质的影响。结果表明:轻剥皮和筛分处理可以有效改善小麦的理化和卫生品质,使小麦的灰分含量降低0.03%,阿拉伯木聚糖含量降低0.04%,容重升高15 g/L,脱氧雪腐镰刀菌烯醇含量降低32.6%,同时轻度剥皮处理对小麦的粗蛋白含量无显著影响(P>0.05)。

In order to explore the cleaning effect of light debranning and screening processes on wheat grains,based on the actual production workshop of a flour mill,a two double-axial debranners corresponding to the light debranning process and a TAS cleaning machine corresponding to the screening process were selected to clean the heavy wheat separated by a gravity grading destoners.By measuring the ash content,crude protein,deoxynivalenol content,and arabinoxylan content of wheat,the effects of light debranning and screening treatment on the physicochemical quality of wheat were analyzed.The experimental results show that light debranning and screening treatment can effectively improve the physicochemical and hygienic quality of wheat.The ash content of wheat is reduced by 0.03%,the arabinoxylan content is reduced by 0.04%,the bulk density is increased by 15 g/L,and the content of deoxynivalenol is reduced by 32.6%.At the same time,light debranning treatment has no significant effect on the crude protein content of wheat(P>0.05).
