At a concentration of 1 μg/μL, whereas differences in the response toward ( E , Z )-2,6-nonadienal remain non-significant, that toward the other five assessed compounds reached the level of significance ( p < 0.05), notably with respect to ( E , E )-2,4-decadienal and 2-hexenal, for which we detected highly significant differences ( p < 0.001).
