啤酒中胺类物质的系统分析
System analysis of amines in beer
摘要
Abstract
Many amine compounds are exist in Beer. Whose taste and quality are closely related to the content and the kind of the amine compounds. A method for trace amine compounds analysis in beer was developed in this paper. The amine compounds withNH2 and NH in beer were analyzed by HPLC separation and LIFD determination, using FITC as derivative regent. Then the nitrosamines in beer were quantitative analyzed by lowtemperature vacuum distillation com bined with GCFID. Further more, various kinds of beer on sell were analyzed. Using the developed method, the result indicated that there existed some differences of amine compounds among different brands and different series of beer. Setting the integral threshold at lmv, the largest number of HPLC peaks is 53 and the least number is 38. In the chromato grams of beer samples, Analyze the content of nitrosamines in three kinds of beer and trace nitrosamines have been de tected in two kinds of them. The method has a high sensitivity, good stability and is easily operated. It can be used for de tection of quality of beer and fake and shoddy products and is valuable significance to control the content of carcinogenic amine compounds. It is very important for the health of people. The method is also suitable for amine compounds analysis in other beverage and food.关键词
