The critical components of hop pellets of three cultivars,Qingdao,Zhayi,Makeboluo were determined and the potential value in beer brewing and storage characteristics of them were studied.The results showed that HSI value of all the pellet products was higher than 0.35;the content of hop oil and α-acid of Makeboluo was the highest in three with the amount as 1.04 mL/100 g and 9.67%±0.15% respectively.However,Zhayi was considered to have the highest brewing value in accordance with the ratio of humulene to carypohyllene,myrcene to the sum of carypohyllene and humulene,and α-acid to β-acid,while the brewing value of Makeboluo was the lowest in three.With nitrogen gas packing,α-acid and hop oil of the pellets lost gradually during storage and the loss rate decreased.β-acid,water,and total phenol content had no significant changing trend.
