Influence of Salting Procedure on the Composition of Muenster-Type Cheese

¹ University of Wisconsin-Madison, Madison 53706

Muenster-type cheeses were salted with a traditional saturated brine solution or by direct addition of salt to the curd. Cheeses were evaluated at 0, 30, 60, 90, 120, and 180 d of age for numbers and type of microflora, casein hydrolysis, and amounts of free fatty acids. No significant differences were found in the populations of starter, lactobacilli, or yeast for the brine- and direct-salted cheeses. The amounts of free fatty acids liberated were similar for both cheeses. The hydrolysis of _s1-casein was complete at 90 d of age, whereas only 40% of the ß-casein was hydrolyzed at 180 d of age. The inner layer of the brine-salted cheeses had the highest number of starter microorganisms, followed by the middle and outer layers, respectively. The salt concentrations were similar in the three layers after 4 mo of age. Results of this study showed that comparable Muenster-type cheese could be produced with either of the salting procedures. With direct salt addition to curd, a 59% reduction was observed in salt emissions from the Muenster manufacturing process.
