Physical and chemical properties of alumina bleached cottonseed oil

Abstract: No detectable amount of polymerization or tr~ene conjugation occurred on bleaching refined cottonseed oil with either activated alumina or with sulfurous acid-treated alumina, although insignificant amounts of diene conjugation and trans-isomerization occurred. AOM stability, tocopherol content, and fatty acid composition, as determined by gas-liquid chromatography (GLC), were comparable with values obtained with oil bleached with natural earth. Hydrogenation of the oils proceeded normally. Taste panel evaluat… Show more

“…Cottonseed oils 112-100 and 113-100 were refined, water washed and vacuum dried oils obtained from a cottonseed oil refinery. Cottonseed oils 112-200 and 113-200 were aliquots of 112-100 and 113-100 that were bleached with sulfurous acid-treated alumina (Pons et al, 1964), while oils 112-300 and 113-300 were aliquots that were bleached with activated alumina (Pons et al, 1963). Oils 112-400 and 113-400 were aliquots of 112-100 and 113-100 that were bleached with Fuller's earth (American Oil Chemist's Society, 1964).…”

“…C OTTONSEED 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(Pons et al, , 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).…”
