Proteolysis in cheese ripening
Webb6 feb. 2013 · INTRODUCTION. Cheese ripening is a complex and dynamic biochemical process involving the breakdown of protein, hydrolysis of fat, and metabolism of lactose.[] Proteolysis is catalyzed by proteolytic enzymes, which originate from the coagulant, milk, starter, and/or non-starter bacteria. WebbBiochemical changes in cheese during ripening may be grouped into primary (lipolysis, proteolysis and metabolism of residual lactose and of lactate and citrate) or secondary (metabolism of fatty acids and of …
