Abstract
Soaps formed in situ removed vitamin A from oils by adsorption, which increased (a) with increase of the water: soap ratio up to 3,000; (b) inversely as the temperature of soap formation; (c) directly with the free fatty acid content of the oil. Percentage adsorption plotted against the original vitamin content of various oils gave a typical adsorption isotherm. Under comparable conditions, a preformed soap adsorbed 7%, a soap formed in situ 39%, of the vitamin. Of various fatty acid soaps investigated, oleates were most effective. The adsorbed vitamin can be recovered quantitatively.
