Abstract

The quality of newly harvested wheat and the changes that may occur during grain storage is of interest to the milling industry. The objective of this work was to study the variations in the industrial quality of durum wheat from the moment of its harvest throughout 7 months of storage. Grain and semolina parameters such as hectoliter weight, one thousand kernel weight, protein, moisture, milling yield, falling number, color, wet and dry gluten content, gluten index and farinograph properties were determined. Grain moisture was below 14% during storage time. Fluctuations of semolina extraction rates during the first months of storage were observed. Extraction values varied from 66 to 73%, stabilizing in 72% at 120 days from harvest. The falling number also presented an increasing tendency. The other quality parameters including gluten and farinograph, showed no significant variations during the storage time. The results indicate that there is no evidence of changes in quality parameters except for milling yield. This suggests the positive effect of blending old wheat with new wheat to minimize fluctuations in milling parameters.

小麦贮藏过程中品质参数的变化

新收获小麦的品质和谷物储存期间可能发生的变化是制粉行业感兴趣的问题。这项工作的目的是研究硬粒小麦从收获的那一刻起在整个7个月的储存过程中工业品质的变化。测定了谷物和小麦粉的参数，如百升重、千粒重、蛋白质、水分、碾磨率、落粒数、颜色、干湿面筋含量、面筋指数和粉谱特性。贮藏期间粮食含水率低于14%。在储存的头几个月里，观察了粗粒面粉提取率的波动。提取值从66%到73%不等，在收获后120天稳定在72%。下降的数量也呈现上升的趋势。其他品质参数包括麸质和淀粉含量在贮藏期间无显著变化。结果表明，除碾磨成品率外，其它质量参数均无明显变化。这表明新旧小麦混合的积极作用，以尽量减少碾磨参数的波动。
