摘要 利用Bradford法和SDS-PAGE电泳技术进行分析,直观地比较了不同蛋白质含量的同品种大麦中热稳定蛋白质与萌发过程中泡沫蛋白质的含量及组成。结果显示,大麦中热稳定蛋白质含量与大麦总蛋白质含量呈正相关,同品种大麦在热稳定蛋白质及泡沫蛋白质含量上虽然存在差异,但其蛋白质组成基本相同;在发芽过程中,高蛋白质含量大麦中的泡沫蛋白质含量略高于低蛋白质含量的大麦。此实验数据及方法可为评估大麦以及预测麦芽和啤酒泡沫的品质提供借鉴。 The contents and components of heat-stable proteins and foam-active proteins was detected by SDS-PAGE and Bradford methods during germination in the same breed barley with different protein content.The results showed the difference in the content of heat-stable protein and foam-active protein and the similar composition of basic protein.
