Flavour enhancers are of great importance to the food industry and the consumer in terms of achieving strong, balanced and preferred product flavour. The understanding and use of flavour enhancers can help to avoid excessive use of individual ingredients such as salt or specific character impact flavours. This chapter first discusses savoury flavour enhancement through the use of ingredients rich in amino acids and 5′-nucleotides. It then includes the potential role of peptides and Maillard-derived compounds. The role of volatile flavour compounds in the enhancement of salt and sweet taste is also discussed.
