| Abstract: | The electrochemical method for semi-automatic detection of reducing sugar in starch sugar was established.The linear range was from 0 to 10.0%, linear correlation coefficient r was 0.9998. Using this method,starch sugar samples were measured and the recovery was 98.9% .Compared with the known methods, reaction was controlled more easily, analysis speed was faster and operation was simpler. |
