The mean dehulling efficiency for red lentils was 81.9%, which was similar to the mean for 2012. Colour of dehulled lentils was measured using a Hunterlab LabScan XE spectrocolorimeter with the CIE L*, a* and b* colour scale. Dehulled splits exhibited more brightness (L*), similar redness (a*) and more yellowness (b*) as compared to dehulled whole seeds. Approximately 75% of red lentils fell within the 4.0 to 5.0 mm range.
