The presence of diethyl-phthalate (DEP), dibutyl-phthalate (DBP), butylbenzyl-phthalate (BBP), diethylhexyl-phthalate (DEHP) and diisononyl-phthalate (DINP) was determined in 295 tequila samples. They were grouped by age of maturation (white, aged, extra aged or ultra aged) and year of production (between 2013 and 2018). Gas Chromatography coupled with Mass Spectrometry was used for identification and quantification. The results showed that 65 samples (22% of the total) were phthalate free. DEP (0.13-0.27 mg/kg), BBP (0.05-2.91 mg/kg) and DINP (1.64-3.43 mg/kg) were detected in 11 (3.73%), 37 (12.54%) and 5 (1.69%) samples, respectively. But, these concentrations did not exceed the maximum permitted limits (MPL) of phthalates for alcoholic beverages. DBP (0.01-2.20 mg/kg) and DEHP (0.03-4.64 mg/kg) were detected in 96 (32.54%) and 224 (75.93%) samples, from them only 10 (3.39%) and 15 (5.08%) samples, respectively, exceeded the MPL for alcoholic beverages and they were few tequilas produced in the year 2014 or before. DEHP was the most frequent phthalate found in tequila and observed DEHP concentrations were 2-times higher in ultra aged tequilas compared to those in white tequilas. We concluded that all tequilas produced in 2015 and after, satisfied the international standards for these compounds.

生产年份减少龙舌兰酒饮料中邻苯二甲酸酯的迁移。

在295个龙舌兰酒样品中测定了邻苯二甲酸二乙酯（DEP），邻苯二甲酸二丁酯（DBP），邻苯二甲酸丁苄酯（BBP），邻苯二甲酸二乙基己基酯（DEHP）和邻苯二甲酸二异壬酯（DINP）的存在。按成熟年龄（白人，年龄，超龄或超龄）和生产年份（2013年至2018年）分组。气相色谱与质谱联用用于鉴定和定量。结果表明65个样品（占总量的22％）不含邻苯二甲酸盐。在11个（3.73％），37个（12.54％）和5个（1.69％）样品中检测到DEP（0.13-0.27 mg / kg），BBP（0.05-2.91 mg / kg）和DINP（1.64-3.43 mg / kg） ， 分别。但是，这些浓度未超过酒精饮料中邻苯二甲酸盐的最大允许限量（MPL）。在96（32.54％）和224（75.）中检出DBP（0.01-2.20 mg / kg）和DEHP（0.03-4.64 mg / kg）。93％的样品中，酒精饮料的MPL分别超过了10（3.39％）和15（5.08％）的MPL，并且在2014年或之前生产的龙舌兰酒很少。DEHP是龙舌兰酒中最常见的邻苯二甲酸酯，观察到的DEHP浓度在超老化龙舌兰酒中是白色龙舌兰酒的2倍。我们得出的结论是，2015年及之后生产的所有龙舌兰酒均满足这些化合物的国际标准。
