Abstract

Abstract: The methods of psychrotrophic bacteria detection was studied in this experiment. Considering that psychrotrophic bacteria could produce a large amount of heat resistance lipase in the milk, the relationship between the lipase vigor and the counts of psychrotrophic bacteria was studied. Then the relationship between lipase and the counts of psychrotrophic bacteria ist entativelyp robed.

Key words: milk, psychrotrophic bacteria, lipase, activity, detection
