Abstract： At present， the commonly used method for measuring the DE value of syrup is the method of

GB/T 20885—2007. This method is relatively mature and simple to operate. However， to obtain an accurate DE value measurement result is affected by many factors. In order to ensure the accuracy of the detection data， this paper discusses the key factors affecting the accuracy of the DE value measurement results， in order to provide reference for related work.
