Abstract
A process for coating a polyunsaturated fatty acid (PUFA)-containing carrier particle or a PUFA matrix particle, or a liquid pharmaceutical-containing carrier particle or a liquid pharmaceutical matrix particle. Also disclosed are such particles made by the process of the invention and foods, pharmaceuticals, beverages, nutritional supplements, infant formula, pet food and animal feed with incorporate such particles.
Claims17
A process for coating a polyunsaturated fatty acid (PUFA)-containing carrier particle or a PUFA matrix particle, the process comprising the steps of:
- (a) metering a liquid coating material through a flow restrictor;
- (b) injecting a gas stream through the flow restrictor concurrently with step (a) to (i) atomize the liquid coating material and (ii) create turbulent flow of the gas stream and the atomized liquid coating material, wherein the gas stream is optionally heated;
- and
- (c) adding a PUFA-containing carrier particle or a PUFA matrix particle to the turbulent flow region concurrently with steps (a) and (b), wherein the PUFA-containing carrier particle or the PUFA matrix particle mixes with the atomized liquid coating material to provide an coated PUFA-containing carrier particle or a PUFA matrix particle.
A process for coating a liquid pharmaceutical-containing carrier particle or a liquid pharmaceutical matrix particle, the process comprising the steps of:
- (a) metering a liquid coating material through a flow restrictor;
- (b) injecting a gas stream through the flow restrictor concurrently with step (a) to (i) atomize the liquid coating material and (ii) create turbulent flow of the gas stream and the atomized liquid coating material, wherein the gas stream is optionally heated;
- and
- (c) adding a liquid pharmaceutical-containing carrier particle or a liquid pharmaceutical matrix particle to the turbulent flow region concurrently with steps (a) and (b), wherein the liquid pharmaceutical-containing carrier particle or the liquid pharmaceutical matrix particle mixes with the atomized liquid coating material to provide an coated pharmaceutical-containing carrier particle or a pharmaceutical matrix particle.
The process of claim I wherein the polyunsaturated fatty acid is selected from the group consisting of γ-linolenic acid (GLA), dihomo-γ-linolenic acid, arachidonic acid (ARA), docosahexaenoic acid (DHA) and/or eicosapentaenoic acid (EPA).
