Abstract
A powder composition containing at least one fat-soluble vitamin dispersed in a matrix of a natural polysaccharide gum or a mixture of gums having an emulsifying capacity and/or a protein or a mixture of proteins having an emulsifying capacity. The fat-soluble vitamin in the powder compositions is in the form of droplets having an average diameter in the range of about 70 to about 200 nm. Tablets, beverages and beverage concentrates, foods, cosmetics and pharmaceuticals containing the powder composition can be made.
Claims21
A powder composition consisting of at least one fat-soluble vitamin dispersed in a matrix consisting of an emulsion-forming composition selected from the group consisting of a natural polysaccharide gum, a mixture of polysaccharide gums, a protein, a mixture of proteins, and mixtures thereof, wherein the fat-soluble vitamin is present in the powder composition in the form of solid droplets having an average diameter of about 80 to about 120 nanometers (nm) and wherein the fat-soluble vitamin is present in the powder composition in the amount of from about 10% to about 30% by weight and wherein the composition has a moisture content of about 1 to 4% by weight.
A powder composition consisting of at least one fat-soluble vitamin dispersed in a matrix of an emulsion-forming composition selected from the group consisting of a natural polysaccharide gum, a mixture of polysaccharide gums, a protein, a mixture of proteins, and mixtures thereof, wherein the fat-soluble vitamin is present in the powder composition in the form of solid droplets, wherein the powder composition is produced by a process comprising:
- (a) combining water with a matrix component selected from the group consisting of a natural polysaccharide gum, a mixture of polysaccharide gums, a protein, a mixture of proteins, and mixtures thereof, to form a solution;
- (b) adding a fat-soluble vitamin to the solution to form a crude emulsion, wherein the fat-soluble vitamin is added in an amount to provide from about 10% to about 30% by weight fat-soluble vitamin in the powder composition;
- (c) emulsifying the crude emulsion at a temperature of from about 5° C. to about 75° C. at a pressure of from about 10,000 psi (about 680 bar) to about 60,000 psi (about 4080 bar), to obtain an emulsion in which the droplets have an average diameter of about 80 to about 120 nm;
- and
- (d) drying the emulsion to obtain the powder composition.
