説明

It was reported in May, 1985 that diethylene glycol (DEG) intentionally added was found in Austrian and German wines. In order to eliminate the growing anxiety of the citizens in Hamamatsu, we investigated the contents of DEG in wine by using the analytical method of DEG specified by the Ministry of Health and Welfare of Japan with some modifications. The DEG in wine was confirmed with an authentic standard in gas chromatography (GC-FID) by using Thermon-3000, PEG-20M, and DEGS as liquid phase as well as in gas chromatography-mass spectrometry, and was finally quantified with GC-FID (PEG-20M). DEG was detected in 5 out of 80 wine samples in the range of 0.015 to 2.3 g/l. It was found that the higher the grade of wine, the higher the tendency of DEG detected. In the course of this study on DEG analysis, 71 samples of wine were found to have glycerin in average amount of 8.3 g/l (13.9-40 g/l), and like DEG, the wines of higher grade tended to have higher amount of glycerin.
