title: Flavouring reduced fat high fibre cheese products with enzyme modified cheeses (EMCs).
abstract: Medium (13%) and low (2%) fat imitation cheeses (pH 6 or 5.5) were flavoured with 5% w/w EMC containing 16%, 28% or 47% total free fatty acids (low to high levels of hydrolysis, respectively) and were examined by a sensory panel. Aroma active short-chain free fatty acids were monitored using gas chromatographic techniques. Regardless of cheese pH or EMC composition, panellists ranked all medium-fat cheeses similarly. Low-fat cheeses flavoured (pH 6 or 5.5) with low or medium lipolysis EMC were described as 'well-balanced' and 'cheesy' and were significantly more preferred to cheeses containing high hydrolysis EMCs. Low-fat cheeses were least preferred of all cheeses because of 'very intense' bursts of off-flavours. Lower pH cheeses were softer and less melting. Higher fat levels in imitation cheese modulated a greater retention of fat-based flavour compounds and improved their release during consumption more than did lower fat levels.
