Product Description

Smoky, like smoked fish or cheese”

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

Guaiacol is contributed to soft drinks through growth of Alicyclobacillus bacteria in raw materials or final product. This organism converts pleasant-tasting vanillin in the product to the less desirable guaiacol. The compound imparts a smoky / disinfectant-like note to affected soft drinks and juices. Similar flavour notes can also arise due to smoke damage of raw materials and / or packaging materials.

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

IMPORTANCE

Guaiacol imparts an undesirable smoky / disinfectant-like note to affected soft drinks and fruit juices. The flavour tends toward a more medicinal note when bromophenols, formed by the same contaminant bacteria, are present.

ORIGINS

The presence of guaiacol in soft drinks can be caused by growth of Alicyclobacillus bacteria in packaged product or in ingredients. This microorganism is acidophilic and survives pasteurization. It converts vanillin present in the product, and derived from ingredients and / or flavourings, to less desirable guaiacol.

HOW TO TASTE

The best way to evaluate smoky, disinfectant-like flavour notes in soft drinks and juices caused by guaiacol 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 guaiacol is 90-05-1.
