Pork-related products such as bacon, sausage and ham comprise a large portion of the meat products sold in today’s market due to their desirable flavour. The application of various processing methods such as cooking, curing, deboning, grinding, canning and application of additives or spices during processing greatly contribute to the characteristic aromas of specific pork-related products. The purpose of this chapter is to provide an integrated overview of the essential flavour constituents in pork products and the presumptive factors affecting pork flavour. Despite large differences among animal species, genetics, and methods used in processing and cooking, this chapter will attempt to focus on consensus odorants that have been studied by at least two independent groups, and will emphasize the heat-induced formation of pork odorants’ pathways.
