Next, the team hope to develop new ingredients for deodorants that fight the smells. “We could make inhibitors that neutralise the precursors, or block the bacterial enzymes that do the conversion,” says Starkenmann. – New Scientist
Not everyone is convinced the Swiss study is valid. Who knows, maybe scientists just wanted to get 49 people in a steamy sauna to see what would happen. Diet and genetic backgrounds may be a greater determining factor in cheesiness.
So all we can formally conclude is the Swiss smell of cheese and onions.
