Carotenoid pigments in Rosa mosqueta hips, an alternative carotenoid source for foods.
Carotenoid composition has been investigated in Rosa mosqueta hips (Rosa rubiginosa, Rosa eglanteria). Six major carotenoids were identified (beta-carotene, lycopene, rubixanthin, gazaniaxanthin, beta-cryptoxanthin, and zeaxanthin) together with other minor carotenoids (violaxanthin, antheraxanthin, and gamma-carotene). An average composition has been estimated as follows: beta-carotene (497.6 mg/kg of dry wt), lycopene (391.9 mg/kg of dry wt), rubixanthin (703.7 mg/kg of dry wt), gazaniaxanthin (289.2 mg/kg of dry wt), beta-cryptoxanthin (183.5 mg/kg of dry wt), zeaxanthin (266. 6 mg/kg of dry wt), and minor carotenoids (67.1 mg/kg of dry wt). Possible uses in food technology are outlined and discussed including the preparation of highly colored oleoresins as natural colorants of food and beverages and as provitamin A sources.
