Carotenoids In Corn Gluten , Daniel Nagy

Retrospective Theses and Dissertations

Existing methods for the isolation of carotenoid pigments have been modified to make them more suitable for the isolation of the isomerized pigment derivatives from corn gluten. Greater recovery of pigments from saponification mixtures may be obtained by the use of concentrated aqueous alkali and centrifuging;Closely related pigments are separable only on mild adsorbents. Deactivated alumina is not suited for such separations. Calcium carbonate showing the necessary selective adsorption has been made by precipitation. The presence of acidic and saponifiable materials hinders adsorption, particularly on mild adsorbants;Acetone is of value as a developing agent. Adsorbents treated with acetone ...
