| Abstract: | The development of the unique flavor of blue type cheese depends on the concerted action of numerous enzymes of Penicillium roqueforti involved in protein and lipid metabolism. Protease(s) by degrading casein modify the texture and background flavor of the ripening cheese. Lipase by hydrolyzing milk triglycerides provides flavorful fatty acids and precursors of methyl ketones. The enzyme complex involved in the partial oxidation of free fatty acids and the properties of β-ketoacyl decarboxylase which generates the major flavor components of blue cheese are discussed. Fermentation of P. roqueforti for the rapid production of methyl ketones is briefly reviewed. |
