Abstract:
Method for spray drying a high-viscosity fluid product using a spraying device, wherein the method comprises projecting the fluid product out of an outflow opening of the spraying device for obtaining droplets of the fluid product, wherein the spraying device is arranged to cause a pressure drop in the fluid product across the outflow opening which is larger than 15 bar and at least partially drying the droplets in a drying medium, such as air, to become particles.
Abstract:
A soluble foaming composition is provided which contains carbohydrate particles having a plurality of voids containing entrapped pressurized gas and less than two percent protein. The composition may include a surfactant and may be contained in a food product such as a beverage mix or an instant food. In addition, a method is provided for manufacturing the foaming composition in which the particles are heated and an external pressure exceeding atmospheric pressure is applied to the soluble foaming particles. The soluble foaming particles are cooled and the external gas pressure is released resulting in pressurized gas remaining in internal voids of the particles of the foaming composition.

Abstract:
The present invention relates to a microencapsulate comprising microcapsules having a diameter of 0.1 μm to 25 μm, said microcapsules comprising: —a core particle having a diameter of 90 nm to 23 μm and containing at least 3% of the active component by weight of said core particle; and—a coating that fully envelops the core particle and containing at least 20 wt. % of a hydrophobic polymer selected from cellulosic ethers, cellulosic esters, zein, shellac, gluten, polylactide, hydrophobic starch derivatives, polyvinyl acetate polymers, polymers or copolymers derived from an acrylic acid ester and/or a methacrylic acid ester and combinations thereof; wherein the core particle contains a release trigger component and/or the coating contains a release trigger component, said release trigger component being selected from: —a water-swellable polymer having a water-uptake capacity at 37° C. and pH 7.0 of less than 20 wt. % and a water-uptake capacity at 37° C. and pH 2.0 of at least 50 wt. %; and—an edible salt having a water solubility at 37° C. and a pH of 7.0 of less than 1 mg/ml and a water solubility at 37° C. and a pH of 2.0 of at least 5 mg/ml; The microencapsulate of the present invention does not release the encapsulated active component when incorporated in water-containing foodstuffs, beverages, nutritional compositions or pharmaceutical compositions. Following ingestion, however, the active component is released rapidly.
Abstract:
The invention concerns a process for preparing particles, which particles contain one or more spaces in which a gas phase is present which comprises at least one active ingredient, in particular at least one aroma, flavor or precursor for an aroma or flavor, and which space or spaces are at least substantially surrounded by an enveloping phase which at ambient temperature is at least substantially solid and at least substantially impermeable to the active ingredient, comprising allowing the gaseous active ingredient to migrate from or through the enveloping phase into the space or spaces at a temperature at which the enveloping phase is permeable to the gaseous active ingredient; and then cooling the particles to a temperature at which the enveloping phase of the particles is at least substantially impermeable to the active ingredient in the particles.
Abstract:
A method is provided for producing a powdered soluble foaming composition comprising amorphous particles having internal voids filled with atmospheric pressure gas. The method includes subjecting a spray-dried composition to an external pressure and heating the composition at a temperature below the glass transition temperature. The composition is depressurized to result in at least a portion of vacuous internal voids of the composition to be filled with atmospheric pressure gas.
Abstract:
The invention relates to a method for preparing particles from an aqueous liquid composition which further contains a composition to form the particles from, wherein the composition is contacted with a supercritical medium, so as to form the particles. The invention further relates to a method for drying aqueous composition, comprising the removal of water from the composition by contacting the composition with a supercritical medium, so as to form a dried product.
Abstract:
A protein-free soluble foaming composition is provided which contains carbohydrate particles having a plurality of voids containing entrapped pressurized gas. The composition may include a surfactant and may be contained in a food product such as a beverage mix or an instant food. In addition, a method is provided for manufacturing the foaming composition in which the protein-free soluble foaming particles are heated and an external pressure exceeding atmospheric pressure is applied to the protein-free soluble foaming particles. The soluble foaming particles are cooled and the external gas pressure is released resulting in pressurized gas remaining in internal voids of the foaming composition.
