Analysis of residual acetaldehyde in PET

Acetaldehyde is an unwelcome by-product that may form during manufacture of polyethylene terephthalate (PET) drinks packaging - impacting end-product quality and consumer satisfaction. 

Acetaldehyde is an issue as it is known to alter the organoleptic properties of beverages, producing a perceived ‘off’, fruity taste or taint. Whilst this may not be a problem for strong flavoured beverages such as fruit juices or soft drinks, it can be undesirable in neutral flavoured products such as mineral water.

Monitoring and minimising the level of acetaldehyde is essential for quality control and consumer satisfaction. Smithers experts provide testing designed to help you detect and measure residual acetaldehyde in PET to avoid unwelcome taints – find out more in this article.
