Abstract
An emulsion system and method for controlling the digestion of a fat or an oil component is provided including a substantially hydrophobic food-grade component, and at least one of an emulsifier component, and one or more of polymeric components, wherein at least one of the emulsifier component and the polymeric component comprises a substantially indigestible food-grade material, such as an indigestible dietary fiber. The emulsifier component and/or the polymeric component can be selected so that the overall interfacial membrane is indigestible to humans and/or animals.
Claims21
An emulsion system for delivery of a food-grade hydrophobic component, the system comprising:
- a dispersion comprising a substantially hydrophobic component in an aqueous medium;
- a first polysaccharide layer component having a net charge incorporated into the dispersion and adsorbed on said hydrophobic component;
- and
- a second polysaccharide layer component incorporated into the system after incorporation of said first polysaccharide layer component and interfacially adsorbed on said first polysaccharide layer component, said second polysaccharide layer component having a net charge opposite said first polysaccharide component net charge, wherein at least one of said first and second polysaccharide layer components is substantially indigestible.
A multi-layer emulsion composition for controlling digestion of a fat or an oil ingredient, the composition comprising:
- a substantially hydrophobic component in an aqueous medium;
- an emulsifier layer component having a net charge adsorbed on said hydrophobic component;
- and
- a first polymeric layer component interfacially adsorbed on said emulsifier layer component, wherein at least a portion of the polymeric component has a net charge opposite that of the net charge of the emulsifier component, wherein at least one of the emulsifier component and the polymeric component comprises a substantially indigestible polysaccharide component,
- said first polymeric component layer adsorbed on said emulsifier layer component subsequent to said emulsifier layer component adsorption on said hydrophobic component.
A multi-layer emulsion composition for controlling digestion of a fat or an oil ingredient, the composition comprising:
- a substantially hydrophobic component in an aqueous medium;
- an emulsifier layer component having a net charge adsorbed on said hydrophobic component;
- and
- a chitosan component interfacially adsorbed on said emulsifier layer component, wherein at least a portion of the chitosan component has a net charge opposite that of the net charge of the emulsifier component.
