Quality of western Canadian lentils 2013

Western Canadian green lentils

Mean protein content for small-size green lentils (CDC Imvincible, CDC Milestone, CDC Viceroy, and Eston) was 27.6%. Mean protein content for medium-size green lentils (CDC Imigreen, CDC Impress, and CDC Richlea) was 27.3%. Protein content for large-size green lentils (CDC Glamis, CDC Grandora, CDC Greenland, CDC Impower, CDC Improve, CDC Plato, CDC Sedley, CDC Sovereign, and Laird) was 27.2%. Mean protein content for both medium-size and large-size lentils was higher than the means for 2012.

Mean starch content for small-size green lentils was higher than the mean for 2012, while the mean for medium-size lentils was lower than the mean for 2012. Mean ash content for all 3 green lentil sizes was similar to levels in 2012.

Mean 100-seed weight for small-size green lentils was 2.4 g. Mean 100-seed weight for medium-size green lentils was 4.4 g. Mean 100-seed weight for large-size green lentils was 5.7 g. Mean 100-seed weights for all 3 sizes of lentils were lower than the means for 2012. Mean water absorption values were 0.74 g H2O per g seeds for small-size lentils, 0.85 g H2O per g seeds for medium-size lentils and 0.88g H2O per g seeds for large-size lentils.

Seed size distribution for green lentils was determined by the image analysis technique. The reported results may differ from those obtained by conventional sieving techniques. For small-size green lentils, approximately 50.0% of the seeds fell within 4.0 to 5.0 mm. For medium-size green lentils, 56% fell within 5.0-6.0 mm. For large-size green lentils, 63% fell within 6.0-7.0 mm.
