Abstract
Rancidity of oils and fats, e.g. cottonseed oil, lard and other shortening products, and cloudiness or seeding out of salad oils such as olive, peanut, and cottonseed, are inhibited by the addition of a small percentage of crude cottonseed oil. The crude oil may first be deodorized without impairment of its antioxidant power, e.g. by blowing with steam, and for food products is preferably free from gossypol. In examples, 1--5 per cent of crude hot-pressed cottonseed oil is added to lard, and 0,5--5,0 per cent to "winterized" cottonseed oil; the latter mixture may be deodorized e.g. by steam. The "winterized" p cottonseed oil is obtained by treating the crude oil with caustic soda to remove free fatty acids and impurities causing colour, maintaining at a low temperature until the harder portions such as tristearin and tri-palmitin crystallize out, filtering, and deodorizing.
