Quality of Canadian food-type soybeans 2021

Harvest samples

Through the Harvest Sample Program, the Canadian Grain Commission received 18 natto-type and 222 generic food-type soybean samples including:

• 10 from the prairies
• 141 from Ontario
• 87 from Quebec
• 2 from the Atlantic region

All samples were graded by Canadian Grain Commission inspectors and were Canada No. 2 or higher.

Composite samples were prepared from each region shown in Figure 1. All composite samples were analysed for:

• 100-seed weight
• water absorption capacity/water uptake factor
• protein content
• oil content
• sugar content
• total isoflavones content

Protein and oil content were determined using a Tecator Infratec 1241 Grain Analyzer near-infrared (NIR) spectrometer, which was calibrated and verified using the appropriate laboratory reference methods. Sugars and isoflavones were analysed by high performance liquid chromatography (HPLC).

Please note that samples reported by grade do not necessarily represent the actual distribution of grade.
