Zusammenfassung:	FIELD: food industry. SUBSTANCE: method comprises grinding and drying natural carotinoid stock, thermooxidizing natural hydrocarbon carotinoid pigments with atmospheric oxygen in original stock and subsequently extracting colorants with ethanol. These operations make it possible to prepare hydrophilized carotinoid colorant dissolved in ethanol and aqueous ethanol solutions. EFFECT: more efficient preparation method. 3 ex, 4 tbl
