| Abstract: | An apparatus for measuring amylose content in grain based on colorimetric measurement is introduced in this paper. An instrument developed in this work has advantages of low cost,simple structure, reliable performance and modularized configuration, which is easy for expansion of software or hardware. The results of comparative measuring tests from an UV-VIS spectrophotometer and our self-developed instrument respectively indicate that the maximum deviation between them was 0.418%, the minimum 0.098%, and the mean 0.220%, which satisfied the accuracy request of amylose content measurement. |
