Product Description

Plastics, like polystyrene or model aeroplane glue”

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

Styrene can contaminate plastic bottles. It can also arise from growth of contaminant yeasts and moulds. Carbonation of soft drinks with defective carbon dioxide is sometimes to blame for this flavour. Styrene imparts a flavour note which is often described as ‘chemical’ with a plastic-like character reminiscent of polystyrene.

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

IMPORTANCE

Styrene is often described by consumers as ‘chemical’, ‘plasticy’ (like polystyrene) or ‘contaminated’. When formed by yeasts or moulds, additional compounds such as 4-vinyl guaiacol and 1,3-pentadiene may be present which can modify the flavour making the drink more 'medicinal', 'smoky' in the case of guaiaco, or like kerosine in the case of pentadiene.

ORIGINS

Styrene can contaminate plastic bottles and, in turn, impart a taint to the soft drinks or juices packaged into these bottles. It can also arise from the action of contaminant yeasts and moulds. Use of defective carbon dioxide is occasionally to blame for styrene contamination incidents.

HOW TO TASTE

The best way to detect the presence of styrene in soft drinks is as follows. Cover the sample with your hand and swirl the glass to release the aroma. Remove your hand and take a single long sniff. Repeat as necessary.

CAS NUMBER

The CAS registry number of styrene is 100-42-5.
