Methods for extraction of carotenoids from carotenoid-containing plant
material using an extraction solvent comprising ethyl lactate. The
invention is also directed to products obtained thereby. In the method, a
sample of dry, particulate carotenoid-containing plant material is
contacted with the ethyl lactate extraction solvent to extract the
carotenoids. The method also includes the use of an ethyl lactate-ethanol
blend as the extraction solvent. After extraction, the solvent containing
the extracted carotenoids is separated from the extracted plant solids
and treated to separate the dissolved carotenoids from the extraction
solvent and obtain a carotenoid-containing concentrate. The concentrated
carotenoid product may be used directly or may be subjected to further
treatment. After removal of the dissolved carotenoids, the extraction
solvent can be recycled for further use.
