折旋光仪在果葡糖浆组分检测中的应用

Application of retractometer and polarmeter in detecting components of fructose syrup

折旋光仪是利用果糖与葡萄糖旋光性及光学叠加性等特性的不同,从而达到快速检测换算出果葡糖浆中葡萄糖和果糖含量的目的。以高效液相色谱检测结果作基准,寻找并消除折旋光仪在检测果葡糖浆组分中的误差,使折旋光仪更快速、高效地应用于果葡糖浆组分的检测中。

The fructose and glucose in fructose syrup can be detected and calculated rapidly by retractometer and polarmeter by using the differences of optical rotation and optical activity. The deviation of polarimeter and retractometer in detecting the components of fructose syrup was found and eliminated on the basis of the detecting result of HPLC. Polarimeter and retractometer can work efficiently in the detection of components of fructose syrup.
