Composition and method for improving stability and extending shelf life of probiotic bacteria and food products thereof

摘要

A composition comprising probiotic bacteria, the composition comprising: (a) a core composition containing the probiotic bacteria and a stabilizer, wherein the total amount of probiotics in the mixture is from about 10% to about 90% by weight of the core composition; (b) an innermost coating layer, layered on said core composition, comprising at least one hydrophobic solid fat or fatty acid having a melting point lower than 60° C.; (c) an intermediate coating layer layered on said innermost coating layer, which when present in an aqueous solution in the amount of 0.1% weight/weight over the weight of the solution, has a surface tension lower than 60 mN/m, when measured at 25° C.; and (d) an outer coating layer, layered on said intermediate coating layer; wherein the composition is in the form of particles; food products containing the composition and methods of preparation thereof.
