Phase relations pertaining to the solvent winterization of crude peanut oil in 85-15 Acetone-hexane mixture

  • Published:
The Journal of the American Oil Chemists’ Society

Summary

Fundamental phase relation data have been obtained on a laboratory scale which show that solvent winterization of crude peanut oil is feasible in a solvent consisting of 85 parts by weight of acetone and 15 parts of commercial hexane. The results show the effect of oil-solvent ratio, chilling temperature, and holding-time upon the percentage of solid removed. The behavior of crude peanut oil is very similar to that of the refined oil in the same solvent except that a slightly lower chilling temperature is required and that the crystals tend to form a little more slowly and do not settle out as readily. The advantage of winterizing hexane-extracted peanut oils before refining is discussed.
