Summary
Oak cask aging enriches rum`s aroma profile. Researchers identified 116 volatile compounds, including seven novel ones, and pinpointed key odorants like vanillin and damascenone that define rum`s complex flavor.
Area of Science:
- Food Chemistry
- Sensory Science
- Distillation and Spirits Analysis
Background:
- Rum`s characteristic aroma is influenced by maturation processes, particularly aging in oak casks.
- Understanding the volatile composition of aged rum is crucial for quality control and flavor development.
Purpose of the Study:
- To comprehensively analyze the volatile compounds present in oak-aged rum.
- To identify key odor-active compounds contributing to the overall aroma profile of rum.
Main Methods:
- Volatile compounds were isolated using solvent extraction and solvent-assisted flavor evaporation.
- Gas chromatography-mass spectrometry (GC-MS) was employed for compound identification.
- Aroma Extract Dilution Analysis (AEDA) and odor activity value (OAV) calculations were used to determine odor impact.
Main Results:
- A total of 116 volatile compounds were identified, with seven being newly reported in rum.
- Eighteen odor-active areas were detected using AEDA.
- Nineteen aroma compounds, including ethanol, (E)-β-damascenone, vanillin, and various esters, exhibited OAVs greater than 1, indicating significant contribution to the aroma.
Conclusions:
- Oak cask aging significantly contributes to the complex volatile profile of rum.
- Specific compounds such as (E)-β-damascenone, vanillin, oak lactone, and several esters are key drivers of rum`s aroma.
- This research provides valuable insights for rum production and quality assessment.

Aromatic Compounds: Overview
14.6K
In general, the term ‘aromatic’ indicates a pleasant smell or fragrance from fresh flowers, freshly prepared coffee, etc. In the early history of organic chemistry, many benzene derivatives were isolated from the pleasant odor oils of the plants. For example, vanillin was isolated from the oil of vanilla, methyl salicylate from the oil of wintergreen, and cinnamaldehyde from the oil of cinnamon. They all had a pleasant odor; hence the name aromatic was given.

NMR Spectroscopy of Aromatic Compounds
6.4K
Aromatic compounds can be identified or analyzed using proton NMR and carbon‐13 NMR. Typically, aromatic hydrogens or hydrogens directly bonded to the aromatic rings are strongly deshielded by the aromatic ring current. Therefore, they absorb in the range of 6.5–8.0 ppm in proton NMR spectra. For instance, aromatic hydrogens directly bonded to the benzene ring absorb at 7.3 ppm. However, aromatic hydrogens of larger rings absorb farther upfield or downfield than the ideal range.

Spectroscopy of Carboxylic Acid Derivatives
3.1K
Infrared spectroscopy is primarily used to determine the types of bonds and functional groups. In carboxylic acid derivatives, a typical carbonyl bond absorption is observed around 1650–1850 cm−1. For esters, the absorption is recorded at around 1740 cm−1, while acid halides show the absorption at about 1800 cm−1. Another acid derivative, the acid anhydrides, exhibit two carbonyl absorption around 1760 cm−1 and 1820 cm−1, arising from the symmetrical and...

Olfactory Receptors: Location and Structure
11.9K
The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...

IR and UV–Vis Spectroscopy of Aldehydes and Ketones
7.5K
Infrared spectroscopy, also known as vibrational spectroscopy, is mainly used to determine the types of bonds and functional groups in molecules. In aldehydes and ketones, the carbonyl (C=O) bond shows an absorption around 1710 cm-1. The C=O bond vibration of an aldehyde occurs at lower frequencies than that of a ketone. In addition to the C=O absorption in an aldehyde, the aldehydic C–H bond also gives two peaks in the 2700–2800 cm-1 range. This absorption, coupled with the...

Olfaction
49.0K
The sense of smell is achieved through the activities of the olfactory system. It starts when an airborne odorant enters the nasal cavity and reaches olfactory epithelium (OE). The OE is protected by a thin layer of mucus, which also serves the purpose of dissolving more complex compounds into simpler chemical odorants. The size of the OE and the density of sensory neurons varies among species; in humans, the OE is only about 9-10 cm2.
