Hop resins are eluted from a specially developed weak anion exchange bonded phase silica using citric acid, methanol, water, mixtures as eluent. Fresh and deteriorated hops and isomerized extracts have been examined. The ratio of the humulone congeners in different hop varieties and the conversion of α‐acid to iso‐α‐acid during the hop boil have been measured.
