Abstract

Contrary to the previous opinion that alkali refining reduces considerably the vitamin A potency of fish liver oils, it has been found that under usual refining conditions the neutralization with alkalis results in increased potency. The increase is approximately proportional to the free fatty acid content of the original oil. The amount of vitamin A carried away by free fatty acids and β€œimpurities” during the refining process has been determined.
