Abstract
Abstract A method of inhibiting mold and psychrotrophic bacteria in creamed Cottage cheese using a mixture of Streptococcus lactis subspecies diacetylacis and Propionibacterium shermanii in the cream dressing or creamed Cottage cheese at refrigeration temperatures is described. The method does allow small volumes of the bacteria causing the inhibition to be used in the Cottage cheese.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
92 words
An improved method for inhibiting mold and psychrotrophic bacteria in creamed Cottage cheese which comprises: (a) inoculating cream dressing for Cottage cheese or creamed Cottage cheese with a mixture of Streptococcus lactis subspecies diacetylactis and Propionibacterium shermanii at a concentration sufficient to inhibit mold and the psychrotrophic bacteria; and (b) storing the creamed Cottage cheese at refrigeration temperatures, wherein the mold and psychrotrophic bacteria are inhibited for an extended period of time during storage, said extended time period being longer than that achieved by Streptococcus lactis subspecies diacetylactis alone in the dressing.
Claim 2
Dependent Claim
92 words
An improved method for inhibiting mold and psychrotrophic bacteria in creamed Cottage cheese which comprises: (a) inoculating cream dressing for Cottage cheese or creamed Cottage cheese with a mixture of Streptococcus lactis subspecies diacetylactis and Propionibacterium shermanii at a concentration sufficient to inhibit mold and the psychrotrophic bacteria; and (b) storing the creamed Cottage cheese at refrigeration temperatures, wherein the mold and psychrotrophic bacteria are inhibited for an extended period of time during storage, said extended time period being longer than that achieved by Streptococcus lactis subspecies diacetylactis alone in the dressing.
Claim 3
Dependent Claim
39 words
The method of claim 1 wherein the Streptococcus lactis subspecies diacetylactis and Propionibacterium shermanii are inoculated into the cream dressing or creamed Cottage cheese at a concentration of each between about 10 5 and 10 8 cells per ml.
Claim 4
Dependent Claim
26 words
The method of claim 1 wherein the ratio of Streptococcus lactis subspecies diacetylactis to Propionibacterium shermanii is between about 1 and 10 and 10 to 1.
Claim 5
Dependent Claim
31 words
The method of claim 3 wherein the concentration of Streptococcus lactis subspecies diacetylactis and Propionibacterium shermanii are each between about 10 6 to 10 7 cells per ml of Cottage cheese.
