Mechanisms of incorporation and release of enzymes into cheese during ripening

The enzymes involved in cheese ripening and the factors affecting their activity in cheese is reviewed. The review begins by outlining the various enzymes that contribute to cheese ripening including those originating from milk, coagulant, starter and non-starter Lactic Acid Bacteria, and those added as exogenous preparations to accelerate flavour development. Factors influencing the retention, release and residual activity of these enzymes in cheese are discussed along with an outline of innovative methods to enhance the retention and release of exogenous enzymes.
