Color of dehusked grain was determined by Hunter-Lab (Ultrascan XE, Hunter-Lab, USA). Prior to color measurements, the instrument was calibrated with light tap and white calibration tile. The colorimeter was set to an illuminant condition D65 and a 10° standard observer. Each sample was put in a cuvette and replaced in to the specular port site, the color parameters (a* b*and L*) were then read (Lamberts et al., 2007). Fifteen replicates for each sample were determined.
