葡萄酒的管道安全分析

采用固相微萃取与气相色谱-质谱结合(SPME-GC-MS)对被污染的具有煤油味的葡萄酒及生产中使用的管道挥发性成分进行分析鉴定,并对不同类型的葡萄酒进行污染情况分析,此外,采用蒸馏和过滤进行去除污染物实验。结果表明,具有煤油味的污染葡萄酒与管道成分十分相似,与管道1和管道2尤为接近,主要为萘、α-甲基萘、β-甲基萘和1,3-二甲基萘,并含有多种苯和萘;干白最易受到污染,其次是经过橡木桶陈酿的干红,桃红受污染最低;过滤和蒸馏都不能完全去除污染物,但是过滤方法明显优于蒸馏。

Analysis of wine’s pipeline safety

The volatile compositions of wine which had been contaminated and full of kerosene smell and the pipe used in wine technology were analyzed by solid phase micro extraction-gas chromatography-mass spectrometry(SPME-GC-MS),and four different types of wine were compared.In addition,distillation and filtration were used to remove contaminants.The results showed that the components of contaminated wine were very similar with pipeline,especially with the pipe 1 and pipe 2.The main contaminants were naphthalene,1-Methylnaphthalene,2-Methylnaphthalene and 1,3-Dimethylnaphthalene,and a variety of benzene and naphthalene.Dry-white wine was the most vulnerable to pollute,followed by oak barrel aging of red wine,rose wine was the minimum pollution.Filtration and distillation could not completely remove the pollutants,but the filtering method was obviously superior to distillation.
