高大平房仓内环流对小麦品质调控作用的研究
|
摘要
本文以天津贯庄国家粮食储备库的高大平房仓为试验仓,采取内环流改造措施的高大平房仓和未进行内环流改造措施的高大平房仓对库内小麦温度、吸水率及其α-淀粉酶活性、总淀粉酶活性的相关的品质进行了研究。结果表明采取内环流改造的高大平房仓对小麦贮藏品质有着较好的调控作用。通过研究结果进行对比分析得出结论:内环流系统改造后,各层粮温分别降低1℃、2.5℃、1.5℃,各层吸水率平均增加4.20%、5.62%、5.34%,还可以有效降低贮藏小麦的α-淀粉酶与总淀粉酶活性,从而使小麦的贮藏品质更加稳定。采用内环流改造可以延长小麦储藏的时间,有效控制小麦的各项品质的同时还可保证小麦稳定性。
This paper takes the tall warehouse of Tianjin Tshuangzhuang National Grain Reserve as the test warehouse. The research content is the high-level warehouse with internal circulation reform measures and the high-level warehouse with no internal circulation reform measures. The results of α-amylase activity and the related quality of total amylase activity were clarified that the high-level greenhouses with internal circulation reform had a good regulation effect on wheat storage quality. The results were compared and analyzed. After the internal circulation system was reformed, the grain temperature of each layer was reduced by 1 ℃, 2.5 ℃, 1.5 ℃, and the water absorption of each layer increased by 4.20%, 5.62%, 5.34%, which can effectively reduce the α-amylase of wheat. The total amylase activity makes the storage quality of wheat more stable. The use of internal circulation reform can prolong the storage time of wheat, effectively control the quality of wheat and ensure the stability of wheat.
