氨基甲酸乙酯（EC）或氨基甲酸乙酯是一种在蒸馏发酵饮料中大量发现的潜在致癌物质，已成为巴西甘蔗烈酒（cachacas）出口的主要技术障碍。在这次评估中，测量了28个生产工厂使用不同蒸馏系统收集的新蒸馏饮料和成品样品中的欧共体水平。来自巴西里约热内卢州的不同地区。采用选择性监测离子m/z和74，通过GC-MS得到的结果表明，约45%的产品和原料高于最大允制值150 μ g/ 1。EC平均值为160 μ g/l。较低的值是使用低温和高回流率蒸馏的脱灰样品的值。强调了这两个变量在欧共体层面的作用。(c) 2007 Elsevier Ltd.版权所有。
Ethyl carbamate (EC) or urethane, a potentially carcinogenic substance found in significant amounts in distilled fermented beverages, has become the main technical obstacle to the exportation of Brazilian sugar cane spirits (cachacas). In this evaluation, the EC levels were measured in samples of recently distilled beverages and of finished products, collected at 28 production plants using different distillation systems. from various regions of the state of Rio de Janeiro. The results obtained through GC-MS, using selective monitoring of ions with m/z and 74, showed that approximately 45% of the products and raw materials are above the maximum allowed value of 150 mu g/ 1. with an EC average value of 160 mu g/l. The lower values were those for samples from alembics using low temperature and high reflux rate distillation. which emphasized the role of these two variables on the EC levels.
