Abstract: The present invention provides microcapsules in which oil comprising unsaturated fatty acids is encapsulated, such as polyunsaturated fatty acids (PUFAs), the invention further relates to a process for preparing the microcapsules. The process comprises the step of adding a plasticizer to the ingredients forming an emulsion, which emulsion may be spray-dried in a subsequent step to form the microcapsules. The presence of the plasticizer and of other constituents of the emulsion and/or the microcapsules synergistically interact so as to results in encapsulated PUFAs having an increased stability and a reduced off-taste.

Abstract: A tobacco product is provided comprising a core-shell capsule with a capsule shell comprising cellulose acetate and/or a derivative thereof. A method of producing a core-shell capsule with a capsule shell comprising cellulose acetate and/or a derivative thereof by diffusion is also provided.

Abstract: The present invention relates to a method for encapsulation and to capsules that can be obtained by the method. The method is characterized by the step of counter-current, diffusional exchange across the membrane of a capsule-shell. During the exchange, a solid primary core is replaced by a liquid that may comprise an active agent. The method of the invention may also comprise a step of further processing said capsules, in particular in order to adjust or modify the release characteristics and to control the release of the active agent inside the capsules.

Abstract: The subject of this invention is a controlled release composition for zootechnical use. In particular, the subject of this invention is a composition comprising micro-pellets that are able to release the physiologically active substances they contain in a controlled manner. In addition, this invention refers to a procedure for preparing said composition as well as the use of said composition in the zootechnical sector.

Abstract: A composition of matter comprising particles which contain choline chloride to be administered in a rumen-protected and post-ruminally effective form, each particle comprising a core which contains choline chloride and a protective coating surrounding the core and protecting choline chloride by ruminal activity while allowing its release into the post-rumen portion of the digestive tract of a ruminant. The core mainly consists of choline chloride in the form of a dry, crystalline powder and, in combination, the protective coating surrounding the core comprises an outer, continuous layer mainly consisting of carnauba wax and an inner, continuous layer consisting of an hydrophobic substance. A feed pellet containing the composition of matter and a premix for feed which contains the composition of matter. A premix for feed which contains feed pellets containing the composition of matter. Mash feed in unpelletted form containing the composition of matter.
