Edible oils are Ultra Processed themsleves
Oil needs to be bland, plain and flavourless, so that it can be used to make edible products that taste good.
To do so, manufacturers refine oil by:
1.
Heating.
2.
Use phosphoric acid to remove gums & waxes.
3.
Neutralise it with caustic soda.
4.
Beach it with bentonite clay.
5.
Deodorise it using high-pressure steam. more
