So cottonseed oil is not generally refined physically because the gossypol can only be removed via caustic stripping. I have a cheap and plentiful supply of degraded (ffa = 14%) cottonseed oil. Can I physically refine it to reduce the ffa then chemically refine it as a way of reducing refining losses?

Depending on how much oil you have, if it is just for a smaller amount for analytical purposes you could use Solid Phase Extraction (SPE) specifically the AccuBond Amino SPE cartridges condition with hexane, add sample, wash through neutral & phospholipids with 2:1 Chloroform:Methanol, then elute free fatty acids with diethyl ether with 2% formic acid.
