Q: Can crude soybean oil be used directly in food products?

No — crude soybean oil (including crude degummed grades) is not food-grade and is not suitable for direct use in food manufacturing or food service. It must be refined (by physical or chemical refining), bleached, and deodorised to produce RBD soybean oil before it can be used in food applications. The refining process removes free fatty acids, residual phospholipids, colour bodies, and off-notes. If you need soybean oil for food use, source refined soybean oil (RBD soybean oil) — not crude.

Crude soybean oil: what it is and who buys it

Crude soybean oil (CSO) is extracted from whole soybeans at soy crushing facilities using hexane solvent extraction, mechanical pressing, or a combination of both. The resulting crude oil is dark-coloured and contains free fatty acids, phospholipids (lecithin), moisture, impurities, and minor components that must be removed before food use. Crude soybean oil is therefore an industrial raw material rather than a food-grade product.

Key commercial grades of crude soybean oil:

Crude degummed soybean oil (CDSO) is the most commonly traded form of crude soy oil. After extraction, a water or acid degumming step removes the bulk of phospholipids (which are recovered as lecithin for separate sale). The degummed crude oil is cleaner than fully crude oil and is the standard traded grade between crushers and refineries. CDSO is specified with maximum phosphorus content (typically ≤50–100 ppm) confirming effective degumming.

Frequently asked questions

What is the soy crush spread and why does it matter for CSO buyers?

The soy crush spread (also called the 'crush margin') is the difference between the combined value of soybean oil and soybean meal produced from one bushel of soybeans and the cost of the soybeans themselves. Refineries and soy crushers monitor the gross processing margin (GPM) closely — when the crush spread widens, more crushing capacity becomes profitable and crude oil supply increases; when it narrows or inverts, some marginal crushing may curtail, tightening supply. For CSO buyers, understanding the crush spread dynamic helps anticipate periods of abundant or tight crude oil availability and supports better timing of forward purchase decisions.

What is the difference between crude degummed soybean oil and lecithin?

During the degumming step in soybean oil processing, water or acid is added to the crude oil to hydrate the phospholipids (phosphatidylcholine, phosphatidylethanolamine, and others), causing them to aggregate and be separated by centrifuge. The separated phospholipid fraction is soybean lecithin — a commercially valuable emulsifier used in chocolate, bakery, and confectionery manufacturing. The remaining oil after degumming is crude degummed soybean oil (CDSO) — with significantly reduced phospholipid content (typically <100 ppm phosphorus). Both lecithin and CDSO are co-products of the same degumming operation.
