Popis: An analytical protocol was developed for investigating short-chain aliphatic amines occurrence in waxes for fruit coating with the aim of controlling their commercialization in countries where the use of these carriers is forbidden. Six short-chain aliphatic amines (morpholine, diethanolamine, triethylamine, 2-dimethylaminoethanol, triethanolamine and 3-metoxypropylamine) were detected by LC/MS/MS operating in positive ion mode in fortified waxes after a two-step clean-up procedure. The analytical method was statistically validated. The matrix-matched regression lines showed r 2 > 0.97. Recoveries ranging from 92 to 114 % were obtained for the fortification level of 3.5 % w/w and the relative standard deviations ranged from 2 to 8 % (n = 6). The limits of detection were below 0.2 % w/w, while the limits of quantification did not exceed 0.5 % w/w. The method is currently applied in ICQRF Laboratory of Catania on samples of coating waxes collected in the Italian market in the frame of MIPAAF institutional quality control activity.
