Probiotic storage and delivery

摘要

Probiotic microorganisms are micro encapsulated by dispersing the probiotic microorganism in an aqueous suspension of a film forming protein and a carbohydrate; in an oil in water emulsion of a film forming protein and a carbohydrate and a fat; or in an oil which is subsequently dispersed in a film forming protein and a carbohydrate. The emulsion or suspension may be dried to form a powder. The probiotic may be dispersed in oil and then emulsified with the aqueous suspension and then dried to produce an encapsulated oil be dried to produce a powder. Oil suspended probiotics may be preferred where the probiotic is water sensitive. The preferred protein is casein or whey protein and the carbohydrate may be a resistant starch or a saccharide with a reducing sugar group. Where the probiotic is oxygen sensitive the protein carbohydrate is heated to create Maillard reaction products in the encapsulating film.

主权项

1. An encapsulated probiotic in which one or more probiotic microorganisms are encapsulated in a protective encapsulant matrix to prolong the storage life of the probiotic, wherein the encapsulant matrix is formed by the combination of a film-firming protein and a carbohydrate in which the encapsulation in the matrix is achieved by
a) mixing a water-dispersible probiotic microorganism in an aqueous suspension of the film-forming protein and the carbohydrate, b) mixing an oil-dispersible probiotic microorganism in an oil-in-water emulsion of the film-forming protein, the carbohydrate, and a fat, or c) mixing the probiotic microorganism in an oil that subsequently is dispersed in an aqueous dispersion of the film-forming protein and the carbohydrate.
