Summary:
Off-flavours and taints are defined as unpleasant odours or tastes, the first resulting from the natural deterioration of a food, the second from its contamination by some other chemical. Both are major problems for the food industry. With its distinguished editor and international team of contributors, this important collection describes some of the most important causes of taints and off-flavours, how they can be identified and dealt with.The book begins with chapters on sensory and instrumental methods for detecting and analysing taints and off-flavours in food. There are chapters o
