Klappentext zu „Flavor of Meat and Meat Products “
Flavour is an important sensory aspect of the overall acceptability of meat products. Whether we accept or reject a food depends primarily on its flavour. Both desirable and undesirable flavour effects are contemplated. Furthermore, threshold values of different flavour-active compounds have an important effect on the cumulative sensory properties of all foods. Meat from different species constitutes a major source of protein for most people. Although raw meat has little flavour and only a blood-like taste, it is a rich reservoir of non-volatile compounds with taste-tactile properties as well as flavour enhancers and aroma precursors. Non-vola tile water-soluble precursors and lipids influence the flavour of meat from different species. In addition, mode of heat processing and the nature of additives used may have a profound effect on the flavour of prepared meats. This book reports the latest advancements in meat flavour research. Following a brief overview, chapters 2 to 5 discuss flavours from different species of meat, namely beef, pork, poultry and mutton. In chapters 6 to 12 the role of meat constituents and processing on flavour are described. The final section of the book (chapters 13 to 15) summarizes analytical methodologies for assessing the flavour quality of meats. I wish to thank all the authors for their cooperative efforts and com mendable contributions which have made this publication possible.
