Abstract
A process for a preparing stable lycopene concentrate in an essentially non-dissolving liquid and uses thereof is described.
Claims32
A process for the preparation of a stable lycopene concentrate which comprises placing lycopene crystals in a liquid medium which does not substantially dissolve lycopene;
- and grinding the lycopene crystals to an average particle size of below about 5 .mu.m.
A stable lycopene concentrate comprising lycopene crystals suspended in a food compatible or cosmetically or pharmaceutically acceptable liquid which does not substantially dissolve lycopene, wherein the lycopene crystals have an average particle size below about 5 .mu.m.
A process for the preparation of a crystalline lycopene composition, comprising mixing a lycopene-containing oleoresin with a solvent or solvent mixture which dissolves the lipid phase of the oleoresin and which does not substantially dissolve lycopene crystals, to remove therefrom a major part of the oleoresin lipids.
A process for the preparation of a stable lycopene concentrate, comprising the steps of:
- a) contacting crude lycopene-containing oleoresin with an acetone/ethyl acetate solvent mixture for a period of time and at a temperature sufficient to dissolve a substantial part of a lipid fraction in the solvent mixture;
- b) separating the mixture to remove a substantial part of the lipid fraction thereby leaving an enriched lycopene fraction;
- c) rinsing the enriched lycopene fraction with hot acetone to remove the acetone soluble materials thereby leaving, after filtration, a crystalline lycopene fraction;
- d) dispersing the crystalline lycopene fraction so obtained in a food-compatible liquid which dissolve does not substantially dissolve lycopene;
- and
- e) size-reducing the lycopene crystals in the food-compatible liquid.
