Application

trans-2-Hexen-1-al was used in evaluation of quality of protected designation of origin virgin olive oils by headspace solid-phase microextraction-gas chromatography using flame ionization detection and multivariate analysis. It was used in the multicomponent method for the determination of low-molecular-weight carbonyl compounds in biological samples.

Trans-2-hexenal, a naturally occurring plant volatile with antimicrobial capacity, was encapsulated into β-cyclodextrins (β-CDs), enzymatically modified starch, and shown effective to control main microorganisms causing food spoilage (Alternaria solani, Aspergillus niger, Botrytis cinerea, Colletotrichum acutatum, Penicillium sp). Loaded β-CDs were
