A crisp, juicy fruit smell with green, sweet and lightly tart associations.
Its type, Source, means the smell is named after “a physical origin that can contribute a smell”; it is not an evidence source, such as a study or a book. The origin page for Apple (the food or drink, not this smell entry) lists every smell recorded as coming from it.
Apple smells crisp, juicy and fresh, opening with a bright green edge and settles into soft sweetness. EDITORIAL

QUESTIONS ABOUT APPLE
Apple smells crisp, juicy and fresh, opening with a bright green edge and settles into soft sweetness. Freshly cut flesh smells cleaner and more tart than the skin, which can feel waxy and faintly floral. The impression is light and watery rather than heavy, fading quickly once the cut surface dries. It can be mistaken for pear, though apple reads sharper and greener.
People meet it in a fruit bowl on the kitchen table, in a lunchbox, or the moment an apple is sliced. Orchards in late summer and autumn carry a fuller version, with fallen fruit warming in the grass.
Typical settings: fruit bowl, freshly cut apple, orchard.
SmellBook links it to one place page: see it in Connections.
2 VERIFIED scientific claims from 2 published sources are recorded for this entry: Many volatiles shape apple aroma and Potent odorants of 'Honeycrisp' apple. Each claim says only what its source supports, in the scope shown with it.
4 molecules are named in one of these claims, Potent odorants of 'Honeycrisp' apple; see the evidence for the role the claim gives them. Each molecule this claim names has only the role the claim states; one molecule is not the whole smell.
Apple is a broad fruit profile whose smell changes across variety, ripeness and cutting state.
SmellBook records 2 written comparisons with other smells: see them in Connections.
Words that are easy to mix up: Is fresh the same as clean?, How do green and herbal differ?, Why is creamy not just sweet? and Is citrus a kind of fresh?

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.

How it is described or perceived
Potent odorants of 'Honeycrisp' apple
In 'Honeycrisp' apples, aroma extract dilution and gas chromatography–olfactometry found hexyl 2-methylbutyrate, α-farnesene, hexanal and (E)-2-hexenal among the most potent odour compounds, and reconstruction and omission tests with sensory analysis suggested that hexyl 2-methylbutyrate is responsible for the cultivar's strong fruity note.
One cultivar; other apples differ, and the abstract also names several alcohols among the most potent compounds.
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: 'Honeycrisp' apples, by dilution analysis, recombination and omission tests.

DOI 10.1016/j.foodchem.2020.127074Chemistry reported
Many volatiles shape apple aroma
A review reports that apple aroma results from the interaction of many volatiles, including esters, alcohols, aldehydes and terpenoids, formed mainly through fatty acid, amino acid, terpenoid and phenylpropanoid metabolism.
Compound classes and pathways, not individual key odorants; aroma varies with cultivar.
How this was found: Broad account. A broad statement about how an aroma forms, how it is studied or what a term means, rather than one measurement. Source: review of earlier studies.

PATHS FROM HERE
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.

FOR RESEARCHERS AND EDITORS
Identity, revision history, corrections and how to cite Apple.
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.
A state says how an entry is met, such as wet, aged or roasted. It does not create a new smell, and it adds no scientific fact by itself: states marked EDITORIAL come from the entry's own records, and only those marked VERIFIED are reported by a VERIFIED claim.
