At this point, a hydrocarbon solvent, typically hexane, is introduced in a massive vessel called a desolventizer toaster, where it percolates through the cake to dissolve the remaining oil, creating a mixture of solvent and crude oil known as miscella. Once the refining is complete, the oil is transported to a storage facility where it is held in large tanks before bottling.
Inside the Canola Oil Production Line: From Flaking to Refining
Prepress Solvent Extraction: The Core Separation For the majority of commercial production, the prepared flakes enter a prepress extractor, where they are cooked under heat and pressure to drive out a significant portion of the oil mechanically. More About How canola oil is made How canola oil is made can be explained clearly by focusing on the most useful facts first and keeping the details easy to follow.
The resulting press cake, though oil-rich, still contains a substantial amount of residual fat that is difficult to remove with pressure alone. Following this preparatory stage, the seeds undergo a critical step known as flaking, where they are crushed into thin, flat pieces to rupture cell walls and increase surface area.

A final deodorization step uses high-temperature steam under vacuum to strip away volatile compounds responsible for off-flavors and odors, resulting in a clear, odorless, and shelf-stable product. Understanding how canola oil is made reveals a sophisticated industrial operation focused on maximizing yield while preserving quality and safety.
