Quality of western Canadian lentils 2015

Western Canadian green lentils

Table 4 shows quality characteristics for green lentil composites by seed size. Mean protein content for small-size green lentils (CDC Imvincible, CDC Viceroy, and Eston) was 26.3%, which was lower than the mean for 2014. Mean protein content for medium-size green lentils (CDC Imigreen, CDC Impress, and CDC Richlea) was 24.1%, which was lower than the mean for 2104. Protein content for large-size green lentils (CDC Glamis, CDC Grandora, CDC Greenland, CDC Impower, CDC Improve, CDC Plato, CDC Sovereign, and Laird) was 26.0%, lower than the mean for 2014. Mean starch contents for medium-size and large-size green lentils were similar to the means for 2014, while the mean for small-size green lentils was higher than the mean for 2014. Mean total dietary fiber contents for small-size and large-size green lentils were similar, but were higher than the mean for medium-size green lentils. Mean ash content for all 3 green lentil sizes was similar to levels in 2014. Potassium (K) was the most abundant macroelement present in green lentils, followed by phosphorus (P), magnesium (Mg) and calcium (Ca) (Table 4). Among microelements, iron (Fe) was the highest, followed by zinc (Zn), manganese (Mn), and copper (Cu).

Mean 100-seed weights for small, medium and large-size green lentils were 3.0 grams, 5.7 grams and 6.7 grams, respectively (Table 4). Mean 100-seed weights for all 3 sizes of lentils were higher than the means for 2014. Mean water absorption values were 0.91 grams H2O per gram seeds for small-size lentils, 0.93 grams H2O per gram seeds for medium-size lentils and 0.97 grams H2O per gram seeds for large-size lentils, which were similar to the means for 2014.

Seed size distribution for green lentils was determined by the image analysis technique (Table 5). The reported results may differ from those obtained by conventional sieving techniques. For small-size green lentils, approximately 78% of the seeds fell within 4.0 to 5.0 millimetres. For medium-size green lentils, 67% fell within 5.0 to 6.0 millimetres. For large-size green lentils, 74% fell within 6.0 to 7.0 millimetres.
