WebbAmong these, proteolysis is considered to be the most important change occurring in cheese and often used as ripening index of cheese. 20.3 Approaches for Accelerating Cheese Ripening The ripening of cheese is a slow and consequently an expensive process as it involves heavy expenditure on refrigeration and labour apart from resulting in loss … 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.
