Some Physiological Properties of Halphen-Positive Cottonseed Oils

Abstract

INTRODUCTIONCOTTONSEED oils bleached with sulfurous acid-treated alumina were reported to differ from conventional cottonseed oils only in the intensity of the red color and in the degree of response to the Halphen test (Pons et al., 1963, 1964). These oils were found to be free of sulfur, to hydrogenate at normal rates and to be indistinguishable organoleptically from normal refined, bleached, and deodorized cottonseed oils (Pons et al., 1964).Physiological differences are reported here between the properties of conventional salad oils of cottonseed origin and oils bleached with sulfurous acid-treated alumina. Hens ingesting cottonseed oils bleached with this reagent produced normal eggs, whereas hens ingesting conventional cottonseed salad oils produced abnormal eggs. The abnormalities appear in the colors and pH values of the yolks and whites and in the fatty acid patterns of the yolk fat (Frampton et al., 1961, 1962; Schaible and Bandemer, 1946; Lorenz et al., 1934; …
