This is the third of a series of three papers on the flavour of milk a
nd dairy products (see also Nursten(1) and Urbach(2)). It deals with t
he taste of cheeses and so concentrates on the water soluble, non-vola
tile fraction. Bitterness is the paramount concern, hydrophobic peptid
es being the principal culprits, but saltiness, sweetness and astringe
ncy are also considered.
