초록 ▼

A process for forming, isolating and purifying xanthophyll crystals, preferably lutein from marigold flower petals, zeaxanthin from wolfberries or capsanthin and capsorubin from red pepper, is disclosed. A xanthophyll diester-containing plant extract is saponified in a composition of propylene glycol and aqueous alkali to form xanthophyll crystals. Crystallization is achieved without the use of added organic solvents. The crystals are isolated and purified. The substantially pure xanthophyll crystals so obtained are suitable for human consumption and can be used as a nutritional supplement and as an additive in food.

대표청구항 ▼

A process for producing xanthophyll crystals from a xanthophyll diester-containing plant oleoresin that comprises the steps of: (a) admixing the oleoresin with propylene glycol with heating to a temperature of about 50°C. to about 60°C. to form a homogeneous liquid; (b) admixing an aqueous alkali solution of sodium or potassium hydroxide with said homogeneous liquid to form a saponification reaction mixture that consists essentially of about 35 to about 50 weight percent oleoresin, about 30 to about 45 weight percent propylene glycol, about 5 to about 10 weight percent alkali as potassium hydroxide and about 7 to about 15 weight percent water as initially admixed components, wherein the total weight of said oleoresin plus propylene glycol constitute at least 75 weight percent of said reaction mixture; (c) maintaining said saponification reaction mixture at a temperature of about 65°C. to about 80°C. for a time period sufficient to saponify the xanthophyll diester and form a saponified reaction mixture containing xanthophyll crystals; (d) admixing about 3 to about 19 volumes of water at a temperature of about 60°C. to about 80°C. per volume of saponified reaction mixture to form a diluted reaction mixture containing xanthophyll crystals; (e) gently admixing said diluted reaction mixture until homogeneous; (f) collecting the xanthophyll crystals from said diluted reaction mixture; and (g) washing and then drying the collected xanthophyll crystals.
