Extraction Methods for Obtaining Carotenoids from Vegetables - Review

Abstract

Due to the potential for health benefits, the importance of carotenoids is growing. Since this group of compounds is used in medical as well as food and cosmetic applications, a review of the current sources of carotenoids is undertaken. A literature survey is presented related to the methods currently used for the extraction of carotenoids from plants: low-pressure solvent extraction by different techniques and supercritical fluid extraction. The process parameters and their influence on carotenoids yield are considered. The cost of manufacturing carotenoids-rich extracts by supercritical fluid extraction is also discussed. Keywords: Carotenoids, manufacturing cost, organic solvent extraction, supercritical fluid extraction, vegetables.
