Abstract
The invention provides olive-derived hydroxytyrosol. According to one aspect of the invention, vegetation water is collected from olives. Acid is added to stabilize the vegetation water and prevent fermentation. The mixture is incubated to allow oleoeuropein to convert to hydroxytyrosol, and then fractionated to separate hydroxytyrosol from other components. The hydroxytyrosol is useful as a natural anti-bacterial, anti-viral and fungicidal product for agricultural and pest control applications. In addition, it is useful as a therapeutic and anti-oxidant for a variety of health purposes.
Claims22
A method of producing a hydroxytyrosol-rich composition, comprising
- (a) producing vegetation water from olives;
- (b) adding acid to the vegetation water in an amount effective to produce a pH between about 1 and about 5.
- (c) incubating the acidified vegetation water for a period of at least two months, until at least 75% of oleoeuropein originally present in the vegetation water has been converted to hydroxytyrosol.
A method of producing a hydroxytyrosol-rich composition, comprising
- (a) producing vegetation water from olives;
- (b) optionally, drying said vegetation water;
- (c) contacting said optionally dried vegetation water with a supercritical fluid;
- and
- (d) recovering said hydroxytyrosol-rich composition from the contacted vegetation water, said hydroxytyrosol-rich composition comprising at least about 95 percent by weight hydroxytyrosol.
A dietary supplement comprising an aqueous extract of olives containing a weight ratio of hydroxytyrosol to oleoeuropein of between about 5:1 and about 200:1.
A dietary supplement comprising an aqueous extract of olives containing a weight ratio of hydroxytyrosol and tyrosol of between about 3:1 and about 50:1.
