Quality of western Canadian lentils 2015

Western Canadian red lentils

Table 6 shows 2015 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 26.0%, which was lower than the mean (27.1%) for 2014. Mean starch content (46.2%) was similar to the mean for 2014. Mean total dietary fiber content was 13.6%. Mean ash content was 2.7%, similar to the mean (2.8%) for 2014. 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 3.8 grams per 100 seeds and the mean water absorption was 0.88 grams H2O per gram seeds, which were higher than the means for 2014.

The mean dehulling efficiency for red lentils was 81.0%, which was slightly higher than the mean for 2014 (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 68% of red lentils fell within the 4.0 to 5.0 millimetre range, which was slightly lower than for 2014 (Table 7).
