Did you know that people lose up to 30% of their ability for their
taste buds to detect salt in food when at altitude?
This means that many companies add extra salt or other flavor profiles to
their food to help it taste palatable inflight.
Since airplane catering companies need to place very large orders of their
ingredients, they tend to place orders very far in advance and have a complex
supply chain, so it is very important to stay ahead of culinary trends and
predict what people might want to eat.
