title: Biotechnological approaches to the understanding and improvement of mature cheese flavour.
abstract: There have been important milestones in biotechnological practice that have led to the determination and production of superior cheese flavours. Within the past year, the use of gas chromatographic techniques and sensory methodologies has been optimised by several groups in efforts to evaluate the organoleptic properties of a number of mature cheeses. The hydrolysis of milk caseins, small peptides, free amino acids and fatty acids, and the generation of sulfur-containing compounds are uniformly assumed to result in the formation of specific cheese aromas. Giant strides have been taken in molecular technology to aid the dissection and exploitation of the metabolic pathways that lead to the formation of these flavour constituents. Specific advances in molecular technology have included metabolic engineering of lactic acid bacteria for enhanced flavour development.
