摘要
采用生物传感器和自动分析仪对玉米浸泡过程中的还原糖、葡萄糖和乳酸进行了测定,并对其变化规律进行了初步探讨。检测结果表明:浸泡液中还原糖、葡萄糖及蛋白质含量随时间先减后增,而乳酸含量则随时间先增后降。采用传感器法测定玉米浸泡液成分较传统方法误差小、操作简单,达到了快速检测的目的。通过本研究,建立了玉米浸泡液成分的快速检测方法,也为浸泡工艺的优化控制提供了依据。
This paper presents a rapid detection method for the composition of corn steep water and provides the basis for optimal control of steeping process. We employ biosensors and an automatic analyzer to determine the contents of reducing sugar, glucose and lactic acid in corn steep water and present their variation rule. Detection results show that the content of reducing sugar, glucose and protein initially decreases and then increases, but the content of lactic acid initially increases and then decreases. Moreover, this biosensor detection method has less error and offers simpler operation, so rapid detection goal can be achieved.
