Printed from smellbook.com/smells/popcorn. This printout keeps the entry for Popcorn itself: its description, reference card, Connections, questions, evidence, related smells, record details, states, names and citation. It leaves out your own notes, the map, the lists of paths, routes, stories and fragrance directions, and the lists headed “Also linked to” (other entries that share its place or material) and “Linked from”; they are on the page online. The entries this one links to are still printed under Connections and Related smells.
Links SmellBook records for this entry: what it comes from, where you meet it, molecules, related smells and comparisons. EDITORIAL links are chosen by SmellBook editors and VERIFIED links come from VERIFIED claims. Nothing here is a ranking, and a molecule is not presented as the cause of the smell.
QUESTIONS ABOUT POPCORN
Popcorn, question by question
What does popcorn smell like? EDITORIAL
Popcorn smells warm and toasted, with a dry grain character, a light nuttiness and a buttery richness when butter is added. The smell is strong and spreads quickly through a room, and sweet versions add a caramel note while salted versions stay plainer. Burnt kernels bring a sharper, acrid edge that lingers.
It drifts from kitchens and microwaves during film nights at home, from cinema foyers and fairground stalls, and from snack bowls passed round at parties and gatherings.
Typical settings: kitchen, movie night, snack bowl.
8 molecules are named in these claims; see the evidence for the role each claim gives them. Each molecule these claims name has only the role its claim states; one molecule is not the whole smell.
How do people describe it, and what is it compared with? EDITORIAL
Popcorn centers the food itself; Cinema Popcorn adds a strong place and ritual context.
Answers marked EDITORIAL are written by SmellBook editors to describe the experience and add no scientific fact. Answers marked VERIFIED point to claims on published sources, checked against each source's own summary where one was available (each claim's page says how); what each claim supports is in its own text and scope.
01WHAT THE EVIDENCE SAYSVERIFIED
What the evidence supports
These 2 VERIFIED scientific claims, from 2 sources, cover how it is described or perceived and the chemistry reported. How the scientific evidence was produced: odour analysis with human assessors and chemical composition. Each claim says only what its source supports, in the scope shown with it.
What is editorial
The description, smell words, associations and related smells on this page are written by SmellBook's editors and labelled EDITORIAL or CULTURAL; a claim below does not make them VERIFIED.
In freshly prepared popcorn, aroma extract dilution analysis detected 23 odorants; the four with the highest flavour dilution factors were 2-acetyl-1-pyrroline (roasty, popcorn-like), (E,E)-2,4-decadienal (fatty), 2-furfurylthiol (coffee-like) and 4-vinyl-2-methoxyphenol (spicy).
Freshly prepared popcorn in one 1991 study; dilution factors rank odour potency in an extract, not amounts.
Also covers: chemistry reported (the claim names compounds or kinds of compounds).
How this was found: Odour analysis with human assessors. People smelled the separated compounds or the material itself (for example gas chromatography–olfactometry, dilution analysis, recombination or a sensory panel). Source: primary study; sensory or perception work. Studied: freshly prepared popcorn, by aroma extract dilution analysis.
A comparison of popped popcorn hybrids suggested that volatiles including 2-furfurylthiol, methional, 4-vinylguaiacol,2-pentylfuran, guaiacol and 2-acetylpyrrole may be partly responsible for typical popcorn aroma.
Six hot-air-popped hybrids; the links are correlations stated tentatively by the authors, without olfactometry.
How this was found: Chemical composition. Compounds were identified or measured, without any assessment of their odour. Source: primary study; chemistry work.
Each molecule is named by the claim shown after it. Each molecule named here has only the role its claim states; one molecule is not the whole smell. About molecules in SmellBook
Each step is a relationship SmellBook editors recorded in the knowledge graph, named as it is published there. Paths are not ranked or personalised, and they do not mean the smells smell alike.
Each step is a molecule that a VERIFIED claim names for both smells, in whatever role the claims state. Sharing a molecule does not mean two smells smell alike.
CULTURAL: This entry's associations depend on context, language, memory or culture; its description and smell words are editorial. It says nothing about research or historical evidence; evidence for this entry is shown separately: VERIFIED.
