Application:	Identification of acetaldehyde based on plasmonic patterns of a gold nanostructure conjugated with chromophore and H(2)O(2): a new platform for the rapid and low-cost analysis of carcinogenic agents by colorimetric affordable test strip (CATS).: This study presents a novel method for detecting acetaldehyde using gold nanostructures, offering a fast, affordable solution for monitoring this carcinogenic compound (Shadjou N et al., 2024 ). Optimisation and characterisation of KOH-activated carbon obtained from Baijiu spent grains for the mitigation of risk factors in alcoholic beverages.: This paper explores the use of KOH-activated carbon for absorbing acetaldehyde from alcoholic beverages, reducing its carcinogenic risk (Sun B et al., 2024 ). Single-site iron-anchored amyloid hydrogels as catalytic platforms for alcohol detoxification.: Discusses the development of novel iron-anchored amyloid hydrogels that catalyze the breakdown of acetaldehyde, a harmful metabolite of alcohol (Mezzenga R et al., 2024 ).
Caution:	May form a small amount of trimer
General description:	Acetaldehyde is an important volatile flavoring compound found in Sherry-like wines and also in many fruits. It is mainly used as a flavoring ingredient in milk products, fruit juices and soft drinks.
