Abstract
PURPOSE:To prepare a transparent and odorless refined oil having a low gamma- linolenic acid content, by treating a soln. of an oil contg. gamma-linolenic acid in a low-boiling hydrocarbon with a column packed with a cation exchange resin for a nonaqueous soln. and a particular adsorbent. CONSTITUTION:A soln. of an oil contg. gamma-linolenic acid in a low-boiling hydrocarbon (e.g., a solution of evening primrose seed oil, lettuce seed oil, black current seed oil, or the like having a high gamma-linolenic acid content in n-pentane, n-hexane, or the like) is treated with a column packed with a cation exchange resin for a nonaqueous soln. (pref. a strongly acidic cation exchange resin) and activated alumina or activated carbon as an adsorbent. The refined oil prepd. by this treatment has a low free fatty acid content and improved hue and odor and exhibits little loss of gamma-linolenic acid caused by adsorption. Since the refined oil is transparent and has mild odor, it is suitable for use not only as a base material for cosmetic preparations but also as a raw material of medicine and health-promoting foods.
