Claims43
An edible concentrated microemulsion of edible essential oil in a matrix of water and alcohol selected from the group consisting of ethanol, propylene glycol, glycerine, sugar, sugar alcohol and mixtures thereof,
- said microemulsion comprising
- about 1 to 25 weight % of said essential oil,
- about 1 to 30 weight % of at least one surfactant, and
- about 25 to 80 weight % of said alcohol, with the balance being water, up to 100 weight %,
- with the provisos that
- said alcohol and said water are present in a weight ratio to each other of about 0.5 to 30,
- said oil and said surfactant are present in a weight ratio to each other of about 0.2 to 5.0,
- said alcohol and said surfactant are present in a weight ratio to each other of about 6 to 20, and
- said surfactant and said oil are present in a weight ratio to each other of about 0.2 to 5.
A ring-less beverage flavored with citrus fruit oil and comprising as said oil imparting component thereof, at least one preformed microemulsion of said oil in a matrix of water and alcohol selected from the group consisting of ethanol, propylene glycol, glycerine, sugar, sugar alcohol and mixtures thereof,
- said microemulsion comprising
- about 1 to 25 weight % of said essential oil,
- about 1 to 30 weight % of at least one surfactant, and
- about 25 to 80 weight % of said alcohol, with the balance being water, up to 100 weight %,
- with the provisos that
- said alcohol and said water are present in a weight ratio to each other of about 0.5 to 30,
- said oil and said surfactant are present in a weight ratio to each other of about 0.2 to 5.0,
- said alcohol and said surfactant are present in a weight ratio to each other of about 6 to 20, and
- said surfactant and said oil are present in a weight ratio to each other of about 0.2 to 5.
An edible concentrated microemulsion of edible essential oil in a matrix of water and alcohol selected from the group consisting of ethanol, propylene glycol, glyerine, sugar, sugar alcohol and mixtures thereof,
- said microemulsion consisting essentially of
- about 1 to 25 weight % of said essential oil,
- about 1 to 30 weight % of at least one surfactant, and
- about 25 to 80 weight % of said alcohol, with the balance being water, up to 100 weight %,
- with the provisos that
- said alcohol and said water are present in a weight ratio to each other of about 0.5 to 30,
- said oil and said surfactant are present in a weight ratio to each other of about 0.2 to 5.0,
- said alcohol and said surfactant are present in a weight ratio to each other of about 6 to 20, and
- said surfactant and said oil are present in a weight ratio to each other of about 0.2 to 5.
A ring-less beverage flavored with citrus fruit oil and consisting of, as said oil imparting component thereof, at least one preformed microemulsion of said oil in a matrix of water and alcohol selected from the group consisting of ethanol, propylene glycol, glycerine, sugar, sugar alcohol and mixtures thereof,
- said microemulsion consisting essentially of
- about 1 to 25 weight % of said essential oil,
- about 1 to 30 weight % of at least one surfactant, and
- about 25 to 80 weight % of said alcohol, with the balance being water, up to 100 weight %,
- with the provisos that
- said alcohol and said water are present in a weight ratio to each other of about 0.5 to 30,
- said oil and said surfactant are present in a weight ratio to each other of about 0.2 to 5.0,
- said alcohol and said surfactant are present in a weight ratio to each other of about 6 to 20, and
- said surfactant and said oil are present in a weight ratio to each other of about 0.2 to 5.
A ring-less cola flavored beverage wherein the cola flavor is, as the flavor oil imparting component thereof, at least one preformed microemulsions of said oil in a matrix of water and alcohol selected from the group consisting of ethanol, propylene glycol, glycerine, sugar, sugar alcohol and mixtures thereof,
- said microemulsion consisting essentially of
- about 1 to 25 weight % of said essential oil,
- about 1 to 30 weight % of at least one surfactant, and
- about 25 to 80 weight % of said alcohol, with the balance being water, up to 100 weight %,
- with the provisos that
- said alcohol and said water are present in a weight ratio to each other of about 0.5 to 30,
- said oil and said surfactant are present in a weight ratio to each other of about 0.2 to 5.0,
- said alcohol and said surfactant are present in a weight ratio to each other of about 6 to 20, and
- said surfactant and said oil are present in a weight ratio to each other of about 0.2 to 5.
