Introduction

Picture this, you are walking into a movie theater, what does it smell like? - Buttery popcorn The smell of popcorn is what we associate to laying back, relaxing, and watching a movie. Today we will dive into the chemistry behind this delicious smell.

Main components of this aroma

Three components that make up this smell are:2-acetyl-1-pyrroline, 2-furfurylthiol, (E,E)-2,4-decadienal.

Formula

2-acetyl-1-pyrroline

It is an aroma and flavour compound present in jasmine rice and basmati rice. It is responsible for the 'popcorn' aroma in a large variety of cereal and food products.

Formula

2-furfurylthiol

Furan-2-ylmethanethiol is an organic compound containing a furan substituted with a sulfanylmethyl group.

Formula

(E,E)-2,4-decadienal

(E, E)-2,4-Decadienal is an aromatic substance found in butter, cooked beef, fish, potato chips, roasted peanut, buckwheat and wheat bread crumb. In an isolated state, it smells of deep fat flavor.

Functional groups

• Ketone: compounds in which the carbon of a carbonyl group is bonded to two other carbons are called ketones.
• Carbonyl group: A carbonyl group is a chemically organic functional group composed of a carbon atom double-bonded to an oxygen atom. The simplest carbonyl groups are aldehydes and ketones.
• Ketimine: Imines are the nitrogen analogues of aldehydes and ketones. Imines derived from ketones are sometimes called ketimines.

Functional groups

• Alkylthiol: Thiols of the structure R-SH are referred to as alkyl thiols, in which an alkyl group (R) is attached to a sulfhydryl group (SH).
• Sulfonyl group: A functional group found primarily in sulfones or to a substituent obtained from a sulfonic acid by the removal of the hydroxyl group similarly to acyl groups.
• Aldehyde: Aldehydes and ketones are organic compounds which incorporate a carbonyl functional group, C=O.
