Trace levels of acrylamide were detected in all samples before heat-treatment, while the concentrations increased in 11 samples out of 16 after heat-treatment. The highest concentration of acrylamide increased from 65.7 ± 6.6 µg kg^-1 before to 119 ± 12 µg kg^-1 after heat-treatment.

Moreover, the results of methanol and ethanol analysis using the proposed method were in good agreement with those obtained from GC-FID analysis which is the conventional method for alcohol analysis. In contrast to GC-FID, the qNMR method for simultaneous alcohol analysis can provide results in a shorter period.

Glyphosate and glufosinate are both widely used herbicides. Glyphosate accounted for one-third of herbicide sales in Europe in 2017 and continues to raise health concerns, including its potential carcinogenicity. While the European Commission extended glyphosate's authorisation for another 10 years in 2023, concerns remain about its impact on biodiversity and human health. This study aimed to monitor the presence of glyphosate, glufosinate, and their metabolites in 100 samples of multifloral honey representing Italian production by analysis using IC-HRMS. Results indicated that 12% of honey samples contained glyphosate residues ranging from > LOQ to 45 ng g^-1, with the highest concentrations detected in the Puglia region. No sample exceeded the maximum residue levels set by EU regulations. Glufosinate and its metabolites were not detected in any samples.
