Abstract
Abstract An herb extract, particularly a member of the Labiatae family of herbs, and especially a rosemary or sage extract, made with acceptable food-grade solvents, in a form which is completely oil soluble, devoid of pro-oxidant materials, and decolorized and if desired deflavorized, to provide an improved form of herb flavoring and/or antioxidant, is disclosed. A process for transforming a crude herb extract into the new form, using food-grade solvents and without chemical modification, is also disclosed.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
235 words
A process for producing a natural antioxidant extract of a Labiatae herb having superior antioxidant activity, which is oil-soluble and which contains essentially all of the antioxidant factors of the natural herb, and which contains less than 7.5% by weight of substances, comprising pro-oxidant substances, which are insoluble in acetone when the extract is diluted to a 15% w/v concentration in acetone at about 20° C., which consists essentially of the steps of: A. Providing an extract of Labiatae herbal material in an approved food-grade organic solvent which contains essentially all of the antioxidant factors of the natural herbal material, B. Removing the solvent to a concentration of about 5 to 50% of the extract in the remaining solvent, until the solvent is no more than about twenty times the weight of the extract, thereby effecting a concentration of between about 5% and 50% of the extract in such solvent, C1. In case the solvent employed is acetone or methylethyl ketone, allowing the solvent and extract mixture to stand until insoluble material precipitates, removing the precipitate, and then removing solvent from the remaining natural antioxidant extract, and C2. In case the solvent employed is not acetone or methylethyl ketone, adding sufficient acetone or methylethyl ketone to precipitate insoluble material and allowing the solvent and extract mixture to stand until insoluble material precipitates, removing the precipitate, and then removing solvent from the remaining natural antioxidant extract.

Claim 3
Dependent Claim
37 words
A process of claim 1, wherein the solvent is selected from the class of edible solvents consisting of acetone, methyl ethyl ketone, lower alcohols, lower esters, and petroleum ethers, said solvent being present singly or in admixture.
Claim 4
Dependent Claim
16 words
A process of claim 1, in which charcoal is added prior to removal of insoluble material.
Claim 5
Dependent Claim
19 words
A process of claim 1, in which the insoluble material is separated in the presence of an edible solvent.
Claim 6
Dependent Claim
24 words
A process according to claim 1, in which the herb essential oil is removed in part or in whole following removal of acetone-insoluble material.
Claim 7
Dependent Claim
11 words
A process of claim 1, in which the solvent is acetone.
Claim 8
Dependent Claim
32 words
A process of claim 1, comprising the step of admixing one or more of the class consisting of an ascorbic acid compound, a tocopherol, and a tumeric compound, into the antioxidant extract.
Claim 9
Dependent Claim
86 words
A process of extracting an herb from the Labiatae family to produce a natural antioxidant extract which is oil soluble and which contains essentially of of the antioxidant factors of the natural herb, with a solvent consisting essentially of acetone or methyl ethyl ketone, with or without the presence of a petroleum ether solvent, removing solvent until the extract is present at a concentration of above about 5% and below about 50%, allowing the mixture to stand until insoluble material precipitates, and removing the insoluble material.
Claim 10
Dependent Claim
86 words
A process of extracting an herb from the Labiatae family to produce a natural antioxidant extract which is oil soluble and which contains essentially of of the antioxidant factors of the natural herb, with a solvent consisting essentially of acetone or methyl ethyl ketone, with or without the presence of a petroleum ether solvent, removing solvent until the extract is present at a concentration of above about 5% and below about 50%, allowing the mixture to stand until insoluble material precipitates, and removing the insoluble material.
Claim 11
Dependent Claim
11 words
The process of claim 2, wherein the lower-alkyl ketone is acetone.
Claim 12
Dependent Claim
140 words
A process of separating antioxidant materials from a Labiatae herbal extract containing essentially all of the antioxidant factors of the natural herb, to produce a natural antioxidant extract which is oil soluble and which contains essentially all of the antioxidant factors of the natural herb, in the presence or absence of an edible organic solvent, by admixing the extact with a petroleum ether solvent, removing the solvent phase and removing solvent therefrom to give a first antioxidant fraction, and admixing the undissolved residual petroleum ether-insoluble fraction with acetone or methylethyl ketone to a point at which the solvent is no more than about twenty times the weight of the extract, and the concentration of extract in the solvent is about 5 to 50%, and separating the soluble and second antioxidant fraction from the still insoluble fraction which comprises pro-oxidant material.
Claim 13
Dependent Claim
140 words
A process of separating antioxidant materials from a Labiatae herbal extract containing essentially all of the antioxidant factors of the natural herb, to produce a natural antioxidant extract which is oil soluble and which contains essentially all of the antioxidant factors of the natural herb, in the presence or absence of an edible organic solvent, by admixing the extact with a petroleum ether solvent, removing the solvent phase and removing solvent therefrom to give a first antioxidant fraction, and admixing the undissolved residual petroleum ether-insoluble fraction with acetone or methylethyl ketone to a point at which the solvent is no more than about twenty times the weight of the extract, and the concentration of extract in the solvent is about 5 to 50%, and separating the soluble and second antioxidant fraction from the still insoluble fraction which comprises pro-oxidant material.
