Application of LC-NMR to analysis of carotenoids in foods.
LC-NMR has been applied to componential analysis of carotenoids in several foods, specifically, tomato juice, palm oil, and satsuma mandarin orange juice. The crude carotenoids extracted with organic solvent from these foodstuffs were analyzed after simple pre-processing. Three, four, and two kinds of carotenoids were identified for tomato juice, palm oil, and satsuma mandarin orange, respectively, primarily by comparing their NMR spectra with those of pure standard.
