Abstract: Encapsulated active components for delivering a desired amount of the active component includes at least one active component encapsulated within a delivery vehicle obtained by cryogenically treating plant material. The active may be a desired flavor that is added to a consumable base to prepare a consumable product, such as food or beverage product, or to prepare an oral care product. Methods for making the delivery systems containing the active component and products containing the encapsulated active component delivery systems are also disclosed.

Abstract: A method of preparing dry core-shell microcapsules from an aqueous dispersion of such capsules, comprising spraying the dispersion through a two-fluid air-liquid nozzle into a heated chamber having an upper part and a lower part, the spraying taking place in the upper part and the lower part being provided with a means of continuous capsule removal. The method allows the drying of capsules with considerably reduced losses.

Abstract: A method of making core-shell capsules containing a water-immiscible liquid, comprising the steps of (a) dispersing into the water-immiscible liquid a crosslinking agent that is inactive under the conditions of the dispersion; (b) emulsifying the resulting dispersion into an aqueous solution of a crosslinkable hydrocolloid; and (c) activating the crosslinking agent to cause the hydrocolloid to crosslink at the dispersion/solution interface. The method is simple and provides capsules that can be cold-loaded. The capsule material may be made of vegetable-derived materials.

Abstract: A critical temperature indicator according to the present invention produces a visual, irreversible indication that the indicator has been subjected to a selected critical temperature. The critical temperature indicator includes a transparent housing, and a temperature sensitive transformable material operably contained within the transparent housing which includes mixture of water, nucleating agent (preferably ice nucleating active (INA) microorganisms), latex, and stabilizer which is translucent prior to exposure of a predetermined temperature and is transformed upon being subjected to the predetermined temperature to render a substantially consistent opaque material thus precluding visibility therethrough and thereby providing a sure visual sign that the indicator has been subjected to the predetermined temperature.

Abstract: A tag or marker applied to a magnetic digital information storage device undergoes a visually observable change when subjected to a magnetic field of preselected intensity to provide visual evidence that the storage device has been degaussed or otherwise subjected to a magnetic field. The tag or marker comprises microcapsules containing an encapsulated mixture of magnetic particle suspended in a suspending vehicle. The magnetic particles have first and second surfaces that provide a visually different appearance depending upon the orientation of the magnetic particles. Upon exposure to the magnetic field of preselected strength or intensity, the magnetic particles change orientation to provide the visual evidence of degaussing.
