This work examines the distilled essential oils of limette and bergamot in order to assess the presence of low volatile substances such as coumarins (bergapten) which, being toxic, must be eliminated before using these oils in the food industry. The quantitative determination of coumarins was carried out by spectrofluorimetric detection. The substances present in the chromatograms, obtained by HPLC with UV detection at 254 nm, were then identified. Moreover, a new coumarin that is present in small quantities was identified using HPLC-MS.

One major problem with the overuse of antibiotics is that the microorganisms acquire resistance; thus the dose must be increased unsustainably. To overcome this problem, researchers from around the world are actively investigating new types of antimicrobials. Zinc oxide (ZnO) nanoparticles (NPs) have been proven to exhibit strong antimicrobial effects; moreover, the Food and Drugs Administration (FDA) considers ZnO as GRAS (generally recognized as safe).
