2.6. Sensory analysis
Sensory evaluation of control and HP-treated cheeses was
carried out by 10 trained panellists from the Technological Agrifood
Institute. A profile of 10 sensory attributes of cheese grouped
in appearance, odour, texture, flavour and taste were analysed.
Analyses were developed in tasting rooms with the conditions
specified in UNE regulation (ISO 8589/1988). All sessions were
conducted at ambient temperature in a sensory panel room
equipped with white fluorescent lighting. The software used for
record scores in sensory sessions was FIZZ Network (version 1.01:
Biosystemes, France). The panel sessions were held mid-morning,
about 3 h after breakfast. In each group, cheeses were presented
individuality and at random. Cheeses were cut in triangular shape
and with 0.2 cm of thickness. Mineral water and bread were
supplied in each session. A quantitative descriptive test was applied
by a 10 cm long non-structured scale 0e10. The attributes evaluated
by panellists were: appearance (colour e from whitish to yellow e
and presence of “eyes”), odour (odour intensity), texture (hardness,
springiness and friability), flavour (flavour intensity) and taste
(salty, sharp and strange tastes)
