QUESTIONS ABOUT ORANGE PEEL
Orange peel smells bright, juicy and zesty, with a sharp burst of citrus at the moment the skin is broken. Behind the sweetness sits a green, slightly bitter edge that keeps it from feeling sugary. The first impression is lively and spray-like, then it softens into a gentler, rounder fruitiness on the fingers. It is fresher and more bitter than orange juice and less sharp than lemon zest.
It is met when peeling an orange at breakfast or as a snack, when grating peel for baking, and in drinks finished with a twist of orange. In some places it is also linked with festive tables and winter fruit bowls.
Typical settings: freshly peeled fruit, breakfast, cocktail garnish.
2 VERIFIED scientific claims from 2 published sources are recorded for this entry: Volatile compounds of citrus rind oils and Aroma-active compounds of sweet orange peel oil. Each claim says only what its source supports, in the scope shown with it.
6 molecules are named in one of these claims, Aroma-active compounds of sweet orange peel oil; 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.
The peel carries a different sensory identity from orange juice or orange flesh.

Chemistry reported
Volatile compounds of citrus rind oils
A review of the volatile composition of the rind essential oil of the ten most studied citrus species, including sweet orange, lemon and bergamot, reports that most of the 49 volatile compounds found in all ten species are terpenoids, and that their volatile composition arranges the species in three clusters.
Composition of rind oils and extracts, not odour: the review does not describe how the peels smell, and it does not imply that orange, lemon and bergamot peel smell alike.
How this was found: Chemical composition. Compounds were identified or measured, without any assessment of their odour. Source: review of earlier studies; chemistry work. Studied: rind essential oils and extracts of ten citrus species, in a review.
M. Carmen González-Mas et al.
DOI 10.3389/fpls.2019.00012Aroma-active compounds of sweet orange peel oil
A gas chromatography–olfactometry study of the peel oil and juice of Jinchen sweet orange found 41 components that appeared to contribute to their aroma; ethyl butanoate, β-myrcene, octanal, linalool, α-pinene and decanal were reported as responsible for the aromatic notes of the juice and peel oil, and panelists described ten compounds as aromatic components of the peel oil only.
One sweet orange cultivar, with the peel oil analysed alongside the juice; the abstract does not say which of the six compounds were perceived in the peel oil itself, and it does not name the ten compounds found only in the peel oil.
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: peel oil and juice of one sweet orange cultivar, by gas chromatography–olfactometry.

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.

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.
