Prepared at the 49th JECFA (1997), published in FNP 52 Add 5 (1997) superseding specifications prepared at the 37th JECFA (1990), published in
FNP 52 (1992). Metals and arsenic specifications revised at the 59th JECFA (2002). No ADI was allocated at the 31st JECFA (1987)
DEFINITION Mixed carotenoids are obtained by solvent extraction of alfalfa, removal of chlorophylls through saponification and subsequent purification of the carotenoids by solvent extraction. The main colouring principle consists of carotenoids of which lutein accounts for the major part. Variable amounts of neoxanthin, violaxanthin and ß-carotene are present.
Mixed carotenoids may contain fats, oils and waxes naturally occurring in the plant material. Vegetable oils may be added for standardizing purposes.
Only the following solvents may be used for the extraction: methanol, ethanol, propan-2-ol, hexane, acetone, dichloromethane and methyl ethyl
ketone. (Note: Articles of commerce may contain approved food additives in order to formulate water soluble products.)
