Influence of pH, type of enzyme and ultrafiltration on the retention of milk clotting enzymes in Camembert cheese

Abstract
Summary: Camembert cheeses were made with pasteurized skim milk or with ultrafiltered milk concentrated 2-fold, using either rennet or Mucor miehei proteinase as coagulant. Using rennet, the rapid acidification during cheesemaking increased enzyme retention and 55% was retained after 24 h. With the M. miehei proteinase, acidification had no effect and only 17% of it was retained after 24 h. The use of ultrafiltered milk resulted in less rennet being retained in the curd.
