Mean protein content for No. 1 Canada Green peas was 23.6%, which was higher than the mean for 2013. Mean protein content for No. 2 Canada Green peas was 23.3%, which was similar to the mean for 2013. Mean starch content was 47.3% for No. 1 Canada Green peas and 47.7% for No. 2 Canada Green peas, slightly higher than the means for 2013. Ash content values for No. 1 and No. 2 Canada Green peas were similar to values in 2013. Similar trends to yellow peas for both macroelements and microelements in green peas were noted. Mean water hydration capacity for No. 1 Canada Green peas (0.76 g H2O per g sample) was similar to the mean for No. 2 Canada Green peas (0.79 g H2O per g sample). The means for both grades were similar to the means for 2013. Mean emulsifying capacity was 279.5 mL oil per g sample for No. 1 Canada Green peas and 280.7 mL oil per g sample for No. 2 Canada Green peas, higher than in 2013. 

Mean 100-seed weight for No. 1 Canada Green peas was 21.1 g, higher than 2013. Mean 100-seed weight for No. 2 Canada Green peas was 19.2 g, slightly lower than 2013. Mean water absorption values for No. 1 and No. 2 Canada Green peas were higher than for 2013. Mean cooking time for No. 1 Canada Green peas was 14.6 min and was 17.1 min for No. 2 Canada Green peas. Mean firmness values for cooked green peas for both grades were slightly higher than values for 2013.
