Soybean Oil Refining

 

2 - Quality control during industrial refining 

 

 

Many analyses can be made concerning the oxidation criteria (peroxide value, oxidized 

lipids, carbonyl value, anisidine value, E.232, E.268, accelerated tests such as the SWIFT 

test.:.) and the other minor components to be removed or inactivated during refining 

(phosphatides, chlorophylls, FFA, soap, hydroperoxides, organochlorine pesticides, trace 

---

metals..) 

 

We only have indicated in Table XIX the control criteria to be made in the factory. 

 

 

3 - Drying 

 

 

It is after the drying step that control criteria should be made concerning the neutralization 

lines.
