Here is an interesting BBC article about a study where researchers found that noise impacts our ability to enjoy and taste foods.
Blindfolded diners assessed the sweetness, saltiness, and crunchiness, as well as overall flavour, of foods as they were played white noise. While louder noise reduced the reported sweetness or saltiness, it increased the measure of crunch.
The article implied that this could be why airline food tastes so bland. Aparently NASA has already encountered this issue and remedied it by giving its astronauts “very strong-tasting foods”.
This makes me wonder if nachos taste extra crunchy at tailgates and sporting events. Could the pairing of nachos and dip derive a bit of their awesomeness from an amplified dichotomy of crunchiness and juiciness? Of course it’s all conjecture at this point but that does present some interesting design potential.
