Determination of bitter iso- alpha-acids and alpha- and beta-hop acids in beer - Food and Beverage - Beverage

It is important to quantify α- and β-hop acids (humulons and lupulons) as well as bitter iso- α-acids (isohumulons) on the all stages of beer production. Hop acids are the biochemical markers of a certain hop type. Bitter iso- α-acids stabilize the beer foam, suppress the growth of undesirable microorganisms and give the beer its bitter taste.
