Disclosed is an electrostatic spray drying process for encapsulating a core material, such as a volatile flavor oil, within a carrier or wall material. The process is achieved by atomizing a liquid emulsion comprising the core material and the wall material, applying an electrostatic charge at the site of atomization, and drying the atomized emulsion into an encapsulated, free-flowing powder. Applying an electrostatic charge at the site of atomization allows the spray drying to be accomplished at significantly reduced temperatures, in particular, inlet temperatures in the range of 25° C. to 110° C., and outlet temperatures in the range of 25° C. to 80° C. The low drying temperatures impart improvements in the resulting encapsulated powdered product, including better retention of volatile flavor components, a flavor profile comparable to that of the starting liquid formulation, and better hydration and dissolution in water-based applications.

The present application relates processes that can be used to produce encapsulated benefit agents comprising a core and a shell that encapsulates said core, encapsulated benefit agents produced by such process and products comprising such encapsulated benefit agents as well as methods of making and using such products. Such process can be used to produce particles that offer the desired protection and release benefits when used in a varity of products.

A method for producing a flowable active material-encapsulated core-shell microcapsule composition by mechanically removing solvent from a microcapsule suspension to produce a wet cake, and subsequently charging the wet cake with a dry flow aid, is provided.

Described are compositions and methods relating to a coated granule comprising a core coated with cross-linkable polymer, where the cross-linkable polymer is applied using a feed suspension that includes an acid-neutralized volatile base and a calcium salt insoluble at the pH of the neutralized feed suspension. Volatilization of the base decreases the pH of the feed suspension, thereby solubilizing the calcium salt, and inducing in situ ion-mediated cross-linking of the cross-linkable polymer.

The present invention relates to a new process for the preparation of microcapsules. Microcapsules obtainable by said process are also an object of the invention. Perfuming compositions and consumer products comprising said capsules, in particular perfumed consumer products in the form of home care or personal care products, are also part of the invention.

Systems and methods for preparing encapsulant-containing polymer capsules and fibers, as well as the encapsulant-containing polymer capsules and fibers and composites including the same are described. In one example, forming a plurality of encapsulant-containing polymer capsules includes preparing a mixture comprising a polymer, a solvent, an encapsulant, and a polymer that is soluble in the solvent, and removing some of the solvent from the mixture to yield the plurality of polymer capsules. Each polymer capsule include a shell formed of the polymer and contains the encapsulant. In another example, forming a plurality of polymer fibers containing an encapsulant includes providing the mixture to an electrospin apparatus and electrospinning the mixture to yield the plurality polymer fibers, where each polymer fiber defines a hollow core that contains the encapsulant.

Microparticles include a matrix of an encapsulating material, in which are dispersed particles of a low melting point fat and a bioactive material, such as one or more probiotic bacteria. The microparticles are formed by preparing an emulsion of melted low melting point fat in an aqueous mixture of the encapsulating material, cooling the emulsion below the melting point of the low melting point fat, dispersing the bioactive material in the emulsion and spray drying the emulsion. The particles of solid low melting point fat are believed to protect the bioactive material from heat damage during the spray drying process.
