Processing Stage Primary Objective Key Outcome Flaking Increase surface area Improved oil extraction efficiency Desolventizing-Toasting Remove solvent and cook cake Safe handling and flavor development Deacidification Neutralize free fatty acids Improved stability and shelf life Despite the rigorous refining process, the naturally occurring compound phytosterol remains largely intact in the final product, contributing to the oil’s reputation as a heart-healthy choice. Understanding how canola oil is made reveals a sophisticated industrial operation focused on maximizing yield while preserving quality and safety.
Canola Oil Factory Workflow: From Flaking to Bottling
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. 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.
This refining stage involves several distinct procedures; neutralization removes free fatty acids using an alkali wash, while bleaching with activated clay eliminates color pigments and impurities. 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.
Canola Oil Factory Workflow: From Flaking to Bottling
Canola oil begins as tiny, golden seeds harvested from the canola plant, a cultivated variety of rapeseed bred specifically for human consumption. The bottling line is a marvel of automation, precisely filling containers under a controlled inert gas atmosphere to minimize oxidation.
