ABSTRACT:
A method for increasing the diacetyl production of a diacetyl-producing bacteria such as Streptococcus diacetylactis. Glycerol or sucrose as humectants are added to an aqueous nutrient medium such as milk having a 2% butterfat content which contains a diacetyl precursor such as sodium citrate. The bacteria are then inoculated into the humectant-containing nutrient medium. The humectant lowers the a.sub.w value of the nutrient medium so as to increase the diacetyl production of the bacteria when incubated at a temperature of from 28.degree. to 37.degree. C.
