前言乙醛是啤酒发酵过程中自然产生的风味物质,其含量的高低影响啤酒的口味评价,乙醛也是反映啤酒成熟度和重要指标之一,对乙醛的分析有助于监控发酵过程是否正常,确保产品质量的稳定性。由于GC价格昂贵,所以采用比色分析方法,并与由GC数据分析的标准样进行比对,减少分析所带来的误差,以用于指导生产。方法适用于发酵过程中的半成品、清 Introduction Acetaldehyde is a natural flavor of beer fermentation process, the content of the level of impact on beer taste evaluation, acetaldehyde is also a reflection of beer maturity and an important indicator of the acetaldehyde analysis helps to monitor the fermentation process is normal , To ensure the stability of product quality. Due to the high cost of GC, colorimetric methods are used and compared with standards analyzed by GC data to reduce the error associated with the analysis and to guide production. The method is suitable for semi-finished products in the fermentation process, clear
