Two Alternative Methods to Predict Amylose Content of Rice ...

This study explores a new way to quantify amylose content in rice using Commission Internationale de l‘Eclairage (CIE L*a*b*) measurements. A specific chart board was created to classify rice amylose content into the five standard classes or more based on true digital colors, after converting CIE L*a*b* values to RGB values which have similarity with human vision. Plant Prod. Sci. 14(2): 164 ...
