摘 要:绿标中对啤酒甲醛的测定方法的反应条件和各试剂的添加量合适;反应形成的紫红色化合物在常温下相当稳定,1h内吸光值基本不会变化;啤酒的除气方式对测定结果有一定的影响;测定结果重复较好,回收率稍差;蒸馏时发生焦糊,易引起测定结果偏高。The reaction conditions of determination methods of formaldehyde in beer by green food standard and the addition quantity of each agent were applicable. The claret compounds were quite stable under normal temperature and there was almost no change in absorbency within 1 h. The gas removal modes in beer had certain effects on formaldehyde determination. The determination results had good repeatability but the recovery rate was a little bad. The scorch of beer in distillation would easily induce the increase of determination results. (Tran. by YUE Yang)
