Quality of western Canadian peas 2015

Protein content

Protein content for yellow and green peas ranged from 17.0% to 28.4% (Table 2). The mean protein content for western Canadian peas was 22.2%, which was lower than the mean of 23.4% for 2014, and lower than the ten-year mean protein content of 23.4 (Figure 2). Table 3 represents the mean protein and starch content for yellow and green peas by crop region (Figure 3).

Figure 2. Mean protein content of western Canadian peas

Graph of mean protein content of western Canadian peas, 2005 to 2015 and 10-year mean. Details below.

The graph depicts the annual average protein content of all peas from 2005 through 2015, and the 10-year (2005-2014) average. Each point represents the average protein content of peas 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 peas (23.4%) over a 10-year period from 2005 to 2014. Average protein contents from 2005, 2006, 2007, 2010, 2012 and 2014 (23.5%, 24.5%, 24.7%, 23.9%, 23.5% and 23.4%, respectively) were all above or equal to the 10-year average of 23.3%, while those from 2008, 2009, 2011, 2013 and 2015 (23.2%, 22.4%, 22.6% ,22.0% and 22.1%, respectively) were below the 10-year average.
