摘要:

为探明白酒在酿造过程中的塑化剂来源,采用气相色谱-质谱联用方法测定白酒酿造的主要原料及各个阶段产物的16 种邻苯二甲酸酯类物质的含量。结果表明,16 种邻苯二甲酸酯类物质的平均回收率和精密度分别为84.5%~107.3%、2.9%~7.3%,方法检出限在0.06~1.3 μg/kg。3 个批次的样品只检出了邻苯二甲酸二甲酯(dimethyl phthalate,DMP)、邻苯二甲酸二乙酯 (diethyl phthalate,DEP)、邻苯二甲酸二异丁酯(diisobutylphthalate,DIBP)、邻苯二甲酸二丁酯(di-n-butyl phthalate,DBP)、邻苯二甲酸二-2-乙基己酯(dioctylpathalate,DEHP)5 种塑化剂。DMP、DBP在大渣酒头、大渣原酒、小渣酒头、渣原酒、回糟原酒中含量明显多于其他阶段。大渣酿酒阶段产生微量的DMP、DBP,小渣酿酒阶段产生微量的DEHP,产生量均未超过0.09 mg/kg,可见白酒酿造过程中产生极微量的塑化剂,在不接触塑料制品的前提下白酒酿造过程中的塑化剂主要来源于原料。

Abstract:

The objective of this study was to investigate the source of 16 phthalate acid esters by gas chromatography-mass
spectrometry (GC-MS) and to detect the contents of phthalate acid esters in the main raw materials and products during
the liquor manufacturing process. The results showed that the average recoveries and precision of 16 phthalate acid esters
were in ranges of 84.5%–107.3% and 2.9%–7.3%, respectively, with limits of detection between 0.06 and 1.3 μg/kg. Five
phthalate acid esters were detected in three batches of samples including dimethy phalate (DMP), diethyl phthalate (DEP),
di-n-butyl phthalate (DBP), diisobutylphthalat (DIBP) and dioctyl pathalate (DEHP). The contents of both DMP and DBP
at the initial and middle stages of distillation were higher than at the late stage. The first fermentation stage produced small
amounts of DMP and DBP. The second fermentation stage produced a small amount of DEHP, and each of the products did
not exceed 0.09 mg/kg. Thus, the liquor manufacturing process produced trace amounts of phthalate acid esters. They were
mainly derived from the raw materials.

Key words: phthalate acid esters, liquor manufacturing process, gas chromatography-mass spectrometry (GC-MS), source
