SEQUENTIAL METHOD FOR PRODUCING PURIFIED, COLD-PRESSED LINSEED OIL WITH ENHANCED WOOD PENETRATION PROPERTIES

摘要

A method for production and purification of linseed oil particularly suitable for deep- penetration treatment of wood, incorporating extracting linseed oil followed by se- quential purification steps, performed under a Nitrogen blanket, said sequential purifi- cation steps involving aqueous acid mediated degumming followed by neutralization and refrigeration (winterization) of said linseed oil in order to precipitate and remove waxy contaminants.
