Other furanic aldehydes and acids can be present in honey, albeit in minor amounts and not always at concentrations high enough to be quantified. While 2-furaldehyde (2-F) and 2-furoic acid (2- FA) originate in variable amounts fromreactions such as hydrolysis [22] and oxidative degradation of ascorbic acid [23], respectively, the origin of 3-furaldehyde (3-F) and 3-furoic acid (3-FA), that have sometimes been quantified in honey samples [24], has yet to be ascertained.
