Studies on the Quality of Fermented Milk

III. An Improved Procedure for the Manufacture of Fermented Milk

Abstract

This paper deals with the improvement of the previously proposed procedure which was based on the application of symbiosis among lactic streptococci for the manufacture of fermented milk by Lact. bulgaricus.
Mother starter for preparing curd was shown to be most suitable when Lact. bulgaricus strain was inoculated in Leichimanii medium and then transplanted to a skim milk solution and cultured for 24 hours at 37°C.
The manufacture of fermented milk was shown to be most effective when the curd was prepared by mixing a 24 hour culture and a 48 hour culture in 1:1 ratio.
