Quality of western Canadian lentils 2015

Protein content

Protein content for green and red lentils in 2015 ranged from 21.5% to 28.9% (Table 2). The mean protein content was 25.9%, which was lower than the mean for 2014 (27.0%), and lower than the 10-year mean of 27.2% (Figure 2). Table 3 represents the mean protein content for green and red lentils by crop region (Figure 3).

Figure 2. Mean protein content of western Canadian lentils

Graph of lentil protein content, 2005 to 2014 and 10-year mean. Details below.

The graph depicts the annual average protein content of all lentils from 2005 through 2015, and the 10-year (2005-2014) average. Each point represents the average protein content of lentils in that crop year. A solid line connects the points, showing the variation of the average protein contents from 2005 through 2015. The dashed line represents the mean protein content of lentils (27.2%) over a 10-year period from 2005 to 2014. Average protein contents from 2006, 2007, 2008 and 2010 (27.4%, 27.6%, 27.9% and 28.0%, respectively) were all above or equal to the 10-year average of 27.2%, while those from 2005, 2009, 2011, 2012, 2013 and 2014 (26.8%, 27.1%, 26.8%, 26.7%, 26.5% and 27.0%, respectively) were below the 10-year average.
