Quality of Canadian oilseed-type soybeans 2015

Harvest sample program

Individual samples were analyzed for oil and protein content using an Infratec 1241 Grain Analyzer near-infrared (NIR) spectrometer, calibrated and verified against the appropriate laboratory reference method. Grade composite samples were analyzed by reference methods for oil, protein, fatty acid composition and free fatty acids. The reference procedures are listed under Oilseeds Methods.

Due to a low number of samples received from some areas, the data presented in this report for these areas might not truly reflect the true quality of the crop. The average data presented in this report were weighted using the 2015 provincial production data as reported by Statistics Canada.

There are two major types of soybeans grown in Canada: those commonly referred to as oilseed-type (“crush” or non-food grade) beans and food grade beans (used for tofu and other soy products). This report deals with the oilseed-type or “non-food grade” soybean samples and could be considered those for the feed or crushing industry. A list of Canadian soybean varieties is provided in Varieties of Crop Kinds which Registered in Canada, Variety Registration Office, Variety Section, Plant Health and Production Division, Canadian Food Inspection Agency

Oilseed-type soybeans are grown to produce oil and high-protein meal. Soybean oil is used in salad oil, shortening and margarine products. Defatted soybean meal is used as a protein supplement in livestock rations. Key quality factors for oilseed soybeans are oil content, protein content, and fatty acid composition. Oil and protein content give quantitative estimates of the beans as a source of oil, and of the defatted meal as a source of protein for animal feed. Fatty acid composition provides information about the nutritional, physical and chemical characteristics of the oil extracted from the beans.
