Cottage cheese is prepared containing a blend of normal and mutant strains of Streptococcus diacetilactis. The mutant strain is similar to the normal strain except that it produces little or no acetaldehyde and diacetyl. By varying the ratio of the strains in the blend, the cottage cheese can be made with the maximum possible shelf life obtainable from Streptococcus diacetilactis and yet have virtually any amount of flavor that may be desired, from very mild to strong.
