Movement of moisture into dry grain can cause the grain to take on a weathered, bleached appearance. Bleaching is a concern for durum producers since the grain price is often discounted. A series of experiments were conducted to determine the effect of grain moisture content, temperature, and wet/dry cycles with bulk water and with high relative humidity on the hydration of durum wheat (Triticum turgidum L. ssp. durum [Desf.] Husn.) grain and their effect on physical grain quality parameters related to bleaching.

水分对硬粒小麦物理品质的影响

水分进入干燥谷物中会导致谷物呈现风化，漂白的外观。由于谷物价格经常打折，因此漂白粉是硬质小麦生产者关注的问题。一系列的实验以测定的颗粒的水分含量，温度的影响，并润湿与本体水，并与硬质小麦的水合高相对湿度（/干燥循环圆柱小麦L. SSP。硬粒[Desf。]希森。谷物及其对与漂白有关的物理谷物品质参数的影响。
