Quality of western Canadian peas 2016 - Protein content

Protein content

Protein content for yellow and green peas ranged from 14.2% to 28.1% (Table 2). The mean protein content for western Canadian peas was 22.1%, which was close to the mean of 22.2% for 2015, but lower than the ten-year mean protein content of 23.2 (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

Mean protein content of western Canadian peas, 2006 to 2016. Details below.

The graph depicts the annual average protein content of all peas from 2006 through 2016, and the 10-year (2006-2015) 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 2006 through 2016. The dashed line represents the mean protein content of peas (23.2%) over a 10-year period from 2006 to 2015. Average protein contents from 2006, 2007, 2008, 2010, 2012, 2014 (24.5%, 24.7%, 23.2%, 23.9%, 23.5% and 23.4%, respectively) were all above or equal to the 10-year average of 23.2%, while those from 2009, 2011, 2013, 2015 and 2016 (22.4%, 22.6%, 22.0%, 22.2% and 22.1% respectively) were below the 10-year average.
