Abstract
Substantially dried free flowing micronutrient compositions having up to 15% by weight of a micronutrient, a binder, and a densifying agent are produced according to the invention. The process for producing the compositions includes the steps of dissolving or dispersing up to approximately 15% by weight of the micronutrient and a binding amount of a binder in water to obtain an aqueous mixture; suspending a densifying amount of a solid densifying agent in the mixture, the densifying agent having a particle size of approximately 40 mesh to approximately 325 mesh; and spray drying the suspension to produce the micronutrient composition.
Claims14
A process for producing a substantially dried micronutrient composition, comprising the steps of:
- (a) dissolving or dispersing up to approximately 15% by weight of the micronutrient and from approximately 7% to approximately 10% by weight of a binder selected from the group consisting of maltodextrin and gelatin in water to obtain an aqueous mixture;
- (b) suspending approximately 75% to approximately 92% by weight of an insoluble solid densifying agent having a particle size ranging from approximately 40 mesh to approximately 325 mesh in the aqueous mixture to form a suspension;
- and
- (c) spray drying the suspension to produce the micronutrient composition, whereby in the composition the micronutrient and the binder are adhered around individual particles of the insoluble solid densifying agent in such a manner that the particle size of the insoluble solid densifying agent determines the particle size of the micronutrient composition.
The process according to claim 8, wherein the densifying agent is calcium sulfate or di-calcium phosphate dihydrate.
A process for producing a vitamin B-12 composition, comprising the steps of:
- (a) dissolving approximately 1% by weight of vitamin B-12 and approximately 10% by weight of maltodextrin in an aqueous solution;
- (b) suspending approximately 89% by weight of calcium sulfate having a particle size ranging from approximately 40 mesh to approximately 325 mesh in the solution to form a suspension;
- and
- (c) spray drying the suspension to produce a vitamin B-12 composition, whereby in the composition the vitamin B-12 and the maltodextrin are adhered around individual particles of the calcium sulfate in such a manner that the particle size of the calcium sulfate determines the particle size of the vitamin B-12 composition.
A substantially dried micronutrient composition comprising up to approximately 15% by weight of a micronutrient and from approximately 7% to approximately 10% by weight of a binder selected from the group consisting of maltodextrin and gelate, the micronutrient and binder being adhered around individual particles of a densifying agent, the total amount of densifying agent representing from approximately 75% to approximately 92% by weight of the composition, the individual particles of densifying agent having a particle size ranging from approximately 40 mesh to approximately 325 mesh, so that particles of the composition are of a size commensurate with the particle size of the densifying agent, the composition having a tapped density of about 0.7 g/cc to about 1.2 g/cc.
A substantially dried vitamin B-12 composition comprising 1% by weight of vitamin B-12 and approximately 10% by weight of maltodextrin, adhered around individual particles of calcium sulfate which form approximately 89% by weight of the composition and have a particle size ranging from approximately 40 mesh to approximately 325 mesh, so that the particle size of the composition formed is commensurate with the particle size of the densifying agent, the composition having a tapped density of about 0.7 g/cc to about 1.2 g/cc.
