一般說明

冰醋酸是一种俗名,用于描述无水状态下的纯醋酸。它是一种透明的吸湿性弱酸,浓度通常为99.5%至100%。名称中的“冰”指的是在略低于室温的温度(16.6°C或61.9°F)下形成的冰状晶体,类似于德语术语“Eisessig”(冰-醋)。尽管被归类为弱酸,冰醋酸是一种腐蚀性毒物,在接触人体组织时,可以导致伤害甚至致命。冰醋酸的不当储存和处理会产生风险,稀释不当会导致患者受伤。醋酸/醋酸酯是肽制剂中的常见反离子。

In this study, SPME was used for the analysis of free fatty acids in Parmesan cheese using a 65 μm Carbowax/divinylbenzene (DVB) SPME fiber. Headspace extraction of the cheese sample was conducted at 65 °C for 15 minutes and analyzed by GC with FID detection. SPME is ideal for analyzing the volatiles associated with solid food samples. The phase chemistry of the Nukol GC column provides excellent peak shape of acidic compounds.
