The barista results come from 14 personal air samples worn by 13 baristas over a work shift: occupational air composition, not the smell of a coffee shop; neither compound is named as the cause of any smell; not every coffee shop; the study's health and exposure-limit findings are outside this claim.","supportCheck":{"method":"phrase-in-abstract","description":"The statement the claim rests on was found word for word in the abstract fetched from the named service, and an editor read the full abstract against every part of the claim."},"sources":[{"id":"SRC-COFFEECAFES-2020","urn":"smellbook:source:coffee-roasting-facilities-and-cafes-air-2020","resolver":"https://smellbook.com/id/source/coffee-roasting-facilities-and-cafes-air-2020","kind":"PRIMARY RESEARCH","title":"Exposures and Emissions in Coffee Roasting Facilities and Cafés: Diacetyl, 2,3-Pentanedione, and Other Volatile Organic Compounds","authors":"Ryan F.
