Cottonseed miscella was treated with FeCl3 to form an iron-gossypol complex. The treated miscella was then extracted with alkaline water. The supernatant lipid filtered through bleaching clay produced an oil containing virtually no light-absorbing color bodies and a product that compared favorably, colorwise, with commercial oil.

Extraction of lipids from cottonseed tissue: IV. Use of hexane-acetic acid
Hexane and mixtures of hexane and 2–25% acetic acid (v/v) were used to prepare oil and protein from glanded cottonseed by solvent extraction. As the amount of acetic acid in the solvent increased,

Production of aflatoxins and norsolorinic acid by a mutant strain ofAspergillus parasiticus follows a similar course. Both substances are completely or partially inhibited when the mutant is grown in


Bleaching of off-colored cottonseed oils
The adsorption of fixed red pigments from refined off-colored cottonseed oil by several adsorbents is described by the empirical Freundlich adsorption isotherm. Numerical values for the coefficient
A method for adsorbent fractionation of cottonseed oil for experimental intravenous fat emulsions
Results of animal screening tests of emulsified cottonseed oils of the glanded and glandless varieties justify attributing some of the undesirable effects to pigments and minor polar component. A
