The applications of SKALAR brand interval flow analyser in the analysis of fermentation liquid and content of product biacetyl were introduced. 介绍利用SKALAR间隔流动分析仪对发酵液、成品双乙酰含量的分析,并对SKALAR与GB法的分析结果进行比较、分析。
The article briefly introduces the production of biacetyl and the relations of fermentation technology and biacetyl.The ways of how to manage the content of biacetyl during beer brewing are discussed. 摘要简述了啤酒中双乙酰的形成机制及发酵工艺与双乙酰的关系,提出了在啤酒实际生产中双乙酰含量的控制方法。
Diacetyl (IUPAC systematic name: butanedione or butane-2,3-dione) is an organic compound with the chemical formula (CH3CO)2. It is a yellow/green liquid with an intensely buttery flavor. It is a vicinal diketone (two C=O groups, side-by-side) with the molecular formula C4H6O2. Diacetyl occurs naturally in alcoholic beverages and is added to some foods to impart its buttery flavor.
