Background noise affects taste of foods, research shows
Baku, October 16 (AZERTAC). The level of background noise affects both the intensity of flavour and the perceived crunchiness of foods, researchers have found.
Blindfolded diners assessed the sweetness, saltiness, and crunchiness, as well as overall flavour, of foods as they were played white noise, BBC reported.
While louder noise reduced the reported sweetness or saltiness, it increased the measure of crunch.
The research is reported in the journal Food Quality and Preference.
It may go some way to explaining why airline food is notoriously bland - a phenomenon that drives airline catering companies to heavily season their foods.
In a comparatively small study, 48 participants were fed sweet foods such as biscuits or salty ones such as crisps, while listening to silence or noise through headphones.
Meanwhile they rated the intensity of the flavours and of their liking.
In noisier settings, foods were rated less salty or sweet than they were in the absence of background noise, but were rated to be more crunchy.
"The evidence points to this effect being down to where your attention lies - if the background noise is loud it might draw your attention to that, away from the food," Dr Woods said.
Also in the group`s findings there is the suggestion that the overall satisfaction with the food aligned with the degree to which diners liked what they were hearing - a finding the researchers are pursuing in further experiments.
