Quality of western Canadian lentils 2016
Western Canadian red lentils
Table 6 shows 2016 quality data for red lentil composites. Mean protein content for red lentils, including the varieties CDC Dazil, CDC Imax, CDC Impact, CDC Impala, CDC Imperial, CDC King Red, CDC Maxim, CDC Redberry and CDC Rouleau, was 26.5%, which was higher than the mean (26.0%) for 2015. Mean starch content (46.6%) was slightly higher than the mean for 2015. Mean total dietary fiber content was 15.6%, higher than the mean for 2015. Mean ash content was 2.9%, higher than the mean (2.7%) for 2015. Results for both macroelements and microelements observed in red lentils had similar trends to those observed in green lentils (Table 6).
Mean 100-seed weight was 3.1 grams per 100 seeds, which was lower than the mean (3.8 grams per 100 seeds) for 2015 and the mean water absorption was 0.96 grams H2O per gram seeds, which were higher than the means for 2015.| Quality parameter | 2016 | 2015 | ||

The mean dehulling efficiency for red lentils was 80.3%, which was slightly lower than the mean for 2015 (Table 6). 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*) and more yellowness (b*) as compared to dehulled whole seeds (Table 6). Approximately 75% of red lentils fell within the 4.0 to 5.0 millimetres range, which was higher than that (68%) for 2015 (Table 7).
