Patent ID: 8828461

Claim:
A process for producing a fermented dairy product with a high probiotic value, which comprises: inoculating a dairy substrate with at least one inoculum; inoculating said dairy substrate with at least one strain of S. thermophilus and at least one strain of L. bulgaricus ; and fermenting said substrate with said at least one inoculum and said strains of S. thermophilus and L. bulgaricus , wherein said inoculum comprises, as a mixture or in the form of a kit of parts: cysteine which is not bound to other amino acids via a peptide linkage; and at least one strain of B. animalis spp. lactis; said cysteine and said at least one strain of B. animalis ssp. lactis each being contained in or in the form of frozen granules and/or lyophilisate(s); said cysteine also being an L-cysteine base the formula for which, in the reduced form, is HSCH 2 CH(NH 2 )CO 2 H, such that a solution obtained after defrosting said granule(s) and/or re-dissolving said lyophilisate(s) in a proportion of 1 to 2 grams of lyophilisate(s) per 8 to 10 mL of H 2 O has a pH of at least 4; said cysteine being present in said inoculum in a quantity of: 1 gram per 1×10 14 cfu of said at least one strain of B. animalis spp. lactis (or, if there are several, said strains of B. animalis spp. lactis ); to 1 gram per 3.5×10 10 cfu of said at least one strain of B. animalis spp. lactis (or, if there are several, said strains of B. animalis spp. lactis ), and wherein the dairy substrate is supplied with up to 20 mg of cysteine per liter of dairy subtrate.
