Abstract
Abstract Starter cultures are produced using a culture medium containing undecalcified sweet whey, undecalcified nonfat dry milk, a nitrogen source and a citrate source. The medium provides the advantages of greater reliability, higher viable bacteria number, and higher acidities in a shorter time. Due to enhanced activity of starter cultures produced on the medium, only about 0.75 to about 1 part starter culture per 100 parts of milk is required in making cheese.
