Abstract
Storage behaviour of groundnut oil obtained by crushing in an expeller or a 'ghani' was studied at 40 degree C and at 2, 67, and 91% RH. The 'ghani' oil had a higher % residual moisture which resulted in a much faster rate of peroxide formation, and in a higher degree of Fe contamination when stored for some time in metallic containers (0.988 p.p.m. vs. 0.255 p.p.m. in expeller-pressed oil). Phosphatide content of 'ghani' oil was only 0.11%, vs. 0.48% in expeller-pressed oil. The lower natural antioxidant action of 'ghani'oil, combined with the higher Fe content, catalyses the autoxidation of the oil.
