    摘要:

    针对偏高水分稻谷过夏储藏期间易发生品质劣变的情况,利用空调控温储粮技术,开展偏高水分稻谷品质变化研究实仓实验,跟踪测定过夏期间水分、脂肪酸值和米饭硬度等质构品质指标的变化情况,结果表明:在高温期间,偏高水分稻谷品质变化情况为水分基本保持不变;脂肪酸值、米饭硬度、胶着性和咀嚼性上升;弹性和粘性下降;内聚性基本不变。由此可见,利用低温储粮技术偏高水分稻谷可以安全过夏,并能达到保持储粮品质,保证储粮安全的目的。

    Abstract:

    Aiming at the situation that high-moisture rice is prone to quality deterioration during the summer storage period, a real warehouse test of high-moisture rice quality change was carried out to track and measure the moisture, fatty acid value and rice hardness during the summer using air-conditioning and temperature-controlled grain storage technology. The change of texture quality index showed that during high temperature weather, the quality changes of high-moisture rice included basically unchanged water remaining; increased fatty acid value, rice hardness, gluing and chewing properties; decreased elasticity and viscosity; basically unchanged cohesion. It can be seen that the high-moisture rice grains can safely survive the summer with the using of low-temperature grain storage technology, and can achieve the purpose of the quality maintaining and safety ensuring of stored grain.
