Abstract:

        This paper employs phenol-sulfuric acid, DNS and reducing sugar analyzer methods to determine the starch content in cornflour. We comprehensively compare their operation processes and the acquired data. Results show that reducing sugar analyzer method can determine maize starch content more conveniently and rapidly.

Key words: phenol-sulfuric acid method, DNS method, reducing sugar analyzer method, maize starch
