During the fermentation of low carbohydrate beer,carbohydrates in wortwas analysed by HPLC. lt was found that the utilization of maltotriose was the key to im-prove the attenuation degree. 运用HPLC法对低糖啤酒发酵过程中糖组分进行了动态分析，发现麦芽三糖的利用效率是发酵度提高的关键所在。
Maltotriose is a trisaccharide (three-part sugar) consisting of three glucose molecules linked with α-1,4 glycosidic bonds.
It is most commonly produced by the digestive enzyme alpha-amylase (a common enzyme in human saliva) on amylose in starch. The creation of both maltotriose and maltose during this process is due to the random manner in which alpha amylase hydrolyses α-1,4 glycosidic bonds.
