粮食霉变和芽变快速检测方法分析

Analysis of Rapid Detection Methods for Mildew and Budding of Grain

霉变和芽变是导致粮食品质劣化的常见因素,研究霉变和芽变的快速检测方法有利于粮食的安全存储。快速检测法将粮食中的过氧化氢酶活性作为判断依据,在检测之前利用高速搅拌机处理霉变或芽变的粮食籽粒,分别获取籽粒外部洗涤液和籽粒匀浆液,再通过酶活性检测仪获取相关数据,可在30 min内完成所有检测操作。经实验探究,快速检测法在灵敏度、稳定性以及不同粮食品种的适应性方面均表现良好,足以达到提高检测速度的目的。

Mouldy and budding are common factors that lead to the deterioration of grain quality. The study of rapid detection methods for mouldy and budding is conducive to the safe storage of grain. The rapid detection method uses the catalase activity in grains as the judgment basis. Before detection, use the high-speed mixer to treat the moldy or budding grain grains, obtain the external washing solution and the grain homogenate respectively, and then obtain the relevant data through the enzyme activity detector. All detection operations can be completed within 30 minutes. Through experimental exploration, the rapid detection method performs well in sensitivity, stability and adaptability of different grain varieties, which is enough to achieve the goal of improving detection speed.
