  • Patent number: 6368633
    Abstract: Described are flavor composition, flavor component, perfume composition and perfume component-containing microparticles which are particulate matrices composed of: (a) an olfactorily active component (e.g., perfume component); (b) silica; and (c) a saccharide composition which is a mixture of mannitol and maltose. The microparticles are useful in augmenting, enhancing and/or imparting aroma and/or taste (over relatively long periods of time in a controllably releasable manner) to perfume compositions, perfumed articles (e.g., deodorancy and antiperspirant sticks), foodstuffs, chewing gums, beverages and the like. Also described is a process for preparing the above-mentioned microparticles using, in sequence, (1) adsorption of the olfactorily active material onto silica followed by (2) a blending/extrusion step followed by (3) at least one particularization step.

  • Patent number: 6042792
    Abstract: Described are controlled, time-release microparticulate active and bioactive compositions (including perfuming compositions) for targeted delivery to services such as skin, hair and fabric and the environment proximate thereto, where the active and bioactive materials have a calculated log.sub.10 P values of between 1 and 8 (P being the n-octanol-water partition coefficient). Such compositions include the active or bioactive material in single phase, solid solution in a wax or polymer matrix also having coated thereon and/or containing a compatible surfactant. Also described are processes and apparatus for preparing such compositions and processes for using same. Furthermore, certain component(s) of the aforementioned compositions in combination with one another are novel, and other components have novel uses in increasing fragrance substantivity.

  • Patent number: 5476675
    Abstract: A process is disclosed for preparing a substantially dry edible flavor fiber product by admixing water, a powdered flavor, a binder and fiber together and extruding the resulting mixture. The process can be carried out by first admixing a powdered flavor material with a fiber to form a flavor-fiber and mixture, then the flavor-fiber mixture is introduced into an extruder where water is simultaneously introduced and the resulting composition, containing water, fiber and flavor is extruded to form a product. The flavor fiber product can be an instant beverage, such as chocolate.

  • Patent number: 4360537
    Abstract: Liproprotein emulsion system composed of protein, edible oil and other selected food ingredients are proposed and used to replace egg yolk and other natural materials in various food products. New and improved processes are described for the preparation of lipoprotein emulsions in a liquid or dry form for use in cake; protein beverages and other food compositions. These processes include methods to improve the solubility and functional properties of the protein component. The lipoprotein system can be used alone or in combination with egg white or other heat coagulable proteins to be a complete or partial substitute for whole eggs. Examples illustrate the practice of this invention to replace egg yolk in cake, donut, muffin, custard and like products.
