Originální abstrakt

The aim of this work was to evaluate the influence of vegetable oils on the sensory quality of model samples of processed cheese analogues. Vegetable oils (grape seed, flaxseed, apricot, black currant) with a high content of biologically active substances were used for production of model samples. The seven-point hedonic scale was used for sensory evaluation of appearance and colour, gloss, texture and taste and aroma (flavour) of samples. The intensity of selected descriptors expressing off-flavour (e.g. sour, oily, bitter, salty, cheesy, pleasant and unpleasant taste) was then evaluated using profile test. The addition of vegetable oils significantly (P<0.05) influenced sensory properties of samples, especially flavour. The sensory evaluation of processed cheese analogues suggests that due to the worse overall sensory quality and the unpleasant oily, synthetic and stale off-flavour, grape and currant oil appears to be rather unsuitable for the production of processed cheese analogues, unlike apricot oil whose sensory quality is comparable to standard (classic processed) cheese containing only butter.
