Abstract
The present invention is an encapsulated yeast composite comprising a core comprising yeast and a coating containing an emulsifiable lipid. The yeast includes Saccharomyces cerevisiae. The invention also relates to other encapsulated bioactive substance composites. The nature of the coating provides controlled release of the bioactive substance from the encapsulate. The encapsulated composites are useful in the production of food compositions, food products, and animal feed products.
Claims62
An encapsulated bioactive substance composite comprising:
- (a) a core which comprises a bioactive substance;
- and
- (b) a coating comprising an emulsifiable lipid, wherein the coating continuously coats the bioactive substance, and wherein the emulsifiable lipid emulsifies upon exposure to a solvent.
A method for controlling rate of release of a bioactive substance from an encapsulated composite upon exposure to a solvent, the method comprising:
- (a) blending an emulsifiable lipid with an amount of one or more additives to obtain a blend;
- and
- (b) coating the bioactive substance with the blend from step (a) to form an encapsulated bioactive substance composite;
- wherein the emulsifiable lipid and additive are not the same, and wherein the rate of release of the bioactive substance from the encapsulated composite is decreased as the amount of additive is increased.
A method for controlling rate of release of a bioactive substance from an encapsulated composite upon exposure to a solvent, the method comprising:
- (a) blending an emulsifiable lipid with an amount of one or more additives to obtain a blend;
- and
- (b) coating the bioactive substance with the blend from step (a) to form an encapsulated bioactive substance composite;
- wherein the emulsifiable lipid and additive are not the same, and wherein the rate of release of the bioactive substance from the encapsulated composite is increased as the amount of additive is decreased.
A method for controlling rate of release of a bioactive substance from an encapsulated composite upon exposure to a solvent, the method comprising coating the bioactive substance with an amount of an emulsifiable lipid to form an encapsulated bioactive substance composite, wherein the rate of release of the bioactive substance from the encapsulated composite is decreased as the amount of emulsifiable lipid based on total weight of the encapsulated composite is increased.
A method for controlling rate of release of a bioactive substance from an encapsulated composite upon exposure to a solvent, the method comprising coating the bioactive substance with an amount of an emulsifiable lipid to form an encapsulated bioactive substance composite, wherein the rate of release of the bioactive substance from the encapsulated composite is increased as the amount of emulsifiable lipid based on total weight of the encapsulated composite is decreased.
