Explanation:
- Major Volatile Compound: The primary volatile compound in cinnamon is cinnamaldehyde.
- Cinnamaldehyde: Cinnamaldehyde is an aldehyde and is responsible for the characteristic aroma and flavor of cinnamon. It is a major component of the essential oil found in the bark of the cinnamon tree.
- Structure: Cinnamaldehyde (C9H8O) has an aromatic phenyl group attached to an unsaturated aldehyde, which gives it its unique scent and properties.
Explanation of Other Options:
Ketone Compound
- Cinnamon does not contain major ketone compounds as its primary volatile compound. Ketones have distinct properties and are separate from the aldehyde group.
Phenolic Compound
- While cinnamon does contain some phenolic compounds, such as eugenol and tannins, they are not the primary volatile compound responsible for its characteristic aroma. Cinnamaldehyde, an aldehyde, is the primary compound.
Ester Compound
- Esters are compounds that typically have fruity odors and are not the major volatile compounds in cinnamon. The primary compound in cinnamon is cinnamaldehyde, an aldehyde.
Additional Information:
- Other Constituents: Besides cinnamaldehyde, cinnamon essential oil contains a variety of other compounds such as eugenol, coumarin, and cinnamic acid, but these are present in smaller quantities.
- Uses: Cinnamaldehyde is used not only for flavoring but also in fragrances, cosmetics, and pharmaceuticals due to its antimicrobial and anti-inflammatory properties.
Conclusion:
- The major volatile compound contained in cinnamon is an aldehyde compound known as cinnamaldehyde, which is primarily responsible for its distinctive smell and flavor.
