ABSTRACT:
A bacteria-containing composition for use in making cottage cheese is prepared containing a strain of Streptococcus diacetilactis that produces substantial amounts of diacetyl in a milk culture, a strain of diacetyl deficient mutant Streptococcus diacetilactis that produces essentially no diacetyl in a milk culture and a suitable carrier for maintaining viability of the Streptococcus diacetilactis. By the use of the two types of Streptococcus diacetilactis, a manufacturer of cottage cheese can optimize both the cell count to achieve the desired inhibition of spoilage bacteria and flavor production to achieve the desired flavor in the finished product.
