Abstract: In this paper, relationship between instrumental test methods traditional measurement methods was studied by using rice eating meter (RCTA 11A) which can determine taste value of rice. The results showed that: There was significant negative correlation between amylose content and taste value, and the relationship between protein content and taste value was significant negative correlation. The low content of amylase and protein improve taste value. There was significant positive correlation between the content of amylase and protein using by instruments and traditional measurement. The instrumental test methods can be using to determine taste value of rice.
