Oilseed Processing Module

Oilseeds and their by-products are valuable ingredients for livestock and poultry. This module will identify components of oilseed processing prior to receipt at feed mill, identify common oilseeds and by-products, list hazards associated with oilseeds and by-products, and identify specialized equipment used to process oilseeds and by-products. This grain module is brought to you by the Iowa Grain Quality Initiative, and was produced by the former Crop Adviser Institute.

Learning objective: Identify common oilseeds and oilseed by-products, learn the components of the oilseed process, explore the specialized equipment needed, and identify potential hazards.

Introduction: Oilseeds and their by-products are valuable ingredients for livestock and poultry. Common oilseeds are sun¬flowers, safflowers, canola, flax, and soybeans. The oil produced is usually used for human consumption, but soybean oilseed meal is most often used in animal feed.

Oilseed processing: Oilseed processing is done by solvent extraction. Multiple steps are taken to remove the hull, flake the meat, extract and refine the oil, and then process the remaining meal appropriately.

Equipment: Specific equipment used during oilseed processing includes: dehullers, flakers, extractors, centrifuges for refinement, the Desolventizer Toaster Dryer Cooler (DTDC) machine, and hammer mills.

Potential hazards: The potential feed safety hazards associated with oilseeds and their by-products include non-grain material, solvent residues, grain chemicals, and mold. However, potential feed safety hazards present a very low risk to animal and human health if consumed.

This module was created at Kansas State University as part of a cooperative agreement with the Food and Drug Administration for food safety inspector training.
