The results of patch testing were read at 48 and 96 hours; testing elicited positive reactions to balsam of Peru and to one of its components, cinnamic aldehyde
Our study shows that chewing gum can be a functional food, having a significant impact on oral hygiene over the short term, if it contains anti-microbial agents such as cinnamic aldehyde
or other natural active compounds," said Christine Wu, professor of periodontics at the University of Chicago and lead author of the study.
Results of the experiment indicated that a certain range of analytes, including cinnamic aldehyde
, cinnamyl acetate, [Alpha]-bisabolol, myristicin, campherenol, and 2-methoxycinnamic aldehyde, is significantly better recovered form the aqueous sample, while higher boiling substances with long-chain hydrophobic groups (e.
With the aforementioned precluded, we tested several other aldehydes, including 2-hexanal, cinnamic aldehyde
, glyceraldehyde, furaldehyde, and 5-hydroxymethyl-2-furaldehyde, together with several compounds such as glycine-MDA, methionine-MDA, and dianil-MDA, which contain the MDA moiety .
