Product Description

Mercaptan, like drains or soft white cheese”

Certified soft drinks flavour standard used to train professional soft drink tasters to recognize and scale the intensity of mercaptan character.

Methanethiol is introduced to soft drinks through use of contaminated carbon dioxide supplies. It can also arise through microbiological spoilage and non-microbiological chemical reactions. It imparts an unpleasant sulphur note to soft drinks, reminiscent of drains or rotting garbage.

Food grade | Free from sensory impurities | Extensively tested | Safe to smell and taste.

IMPORTANCE

Methanethiol imparts an unpleasant sulphury note to soft drinks. The compound is easily oxidized to less odour-active species, so its presence is indicative of the failure of water treatment processes or contamination during production of soft drinks.

ORIGINS

Methanethiol is a contaminant introduced into carbonated soft drinks through use of insufficiently-purified carbon dioxide. The compound can also arise through microbiological spoilage and through non-microbiological chemical reactions.

HOW TO TASTE

The best way to detect mercaptan character in soft drinks is as follows. Without covering the glass, swirl the sample to release the aroma. Take a single short sniff. Repeat as necessary.

CAS NUMBER

The CAS registry number of methanethiol is 74-93-1.
