气调储藏对小麦籽粒加工品质的影响

Effect of controlled atmosphere storage on processing quality of wheat grain

经过4个月储藏后,在常规储藏条件下,面筋吸水量:高筋麦下降24%,中筋麦下降32%,低筋麦下降26%;降落数值:高筋麦上升69s,中筋麦上升44s,低筋麦上升20s;在充二氧化碳气调储藏条件下,面筋吸水量:高筋麦下降16%,中筋麦下降21%,低筋麦下降16%;降落数值:高筋麦上升51.5 s,中筋麦上升34.5 s,低筋麦上升15 s;在充氮气调储藏条件下,面筋吸水量:高筋麦下降11%,中筋麦下降18%,低筋麦下降11%;降落数值:高筋麦上升40.5 s,中筋麦上升25.5 s,低筋麦上升6.5 s;综上,气调储藏相对于常规储藏方式而言,能显著降低小麦品质劣变速度,有效地保持小麦籽粒的加工和储藏品质。

After four months of storage, under conventional storage conditions, the water uptake of highgluten wheat decreased by 24%, medium-gluten wheat by 32% and low-gluten wheat by 26%. The falling value of high-gluten wheat increased by 69 s, medium-gluten wheat by 44 s and low-gluten wheat by 20 s. Under controlled atmosphere storage with carbon dioxide, the water uptake of high-gluten wheat decreased by 16%, medium-gluten wheat by 21%, low-gluten wheat by 16%, the falling value of highgluten wheat by 51.5 s, medium-gluten wheat by 34.5 s and low-gluten wheat by 15 s. Under the condition of controlled atmosphere storage with nitrogen, the water uptake of high gluten wheat decreased by 11%, medium gluten wheat by 18%, low gluten wheat by 11%, the falling value of high gluten wheat by 40.5 s, medium gluten wheat by 25.5 s and low gluten wheat by 6.5 s. In conclusion, compared with conventional storage methods, controlled atmosphere storage can significantly reduce the deterioration rate of wheat quality and effectively maintain the processing and storage quality of wheat grains.
