Activated release of bioactive aldehydes from their precursors embedded in electrospun poly(lactic acid) nonwovens.

Hexanal and benzaldehyde are naturally-occurring aroma compounds from plants with enzyme-inhibition and antimicrobial properties. Although useful for food preservation applications, the end-use of these compounds can be challenging due to their volatility and susceptibility to oxidative degradation. In this study, stable precursors for benzaldehyde and hexanal were synthetized reversible condensation reactions with ,'-dibenzylethane-1,2-diamine.
