Hop beta acids
Hop beta acids (lupulone, colupulone, adlupulone) are bitter resins of Humulus lupulus cones, less bitter and less water-soluble than alpha acids, with strong antimicrobial activity against Gram-positive bacteria and GRAS status (GRN 63) for meat products.
Hop bitter acids
Hop bitter acids are prenylated acylphloroglucinol secondary metabolites of the hop plant (Humulus lupulus), divided into alpha-acids such as humulone and beta-acids such as lupulone.
Lupulone
Lupulone (beta-lupulic acid, CAS 468-28-0), a C26H38O4 beta-bitter acid from hops (Humulus lupulus), 30-55% of hop beta-acids; poorly water-soluble, non-isomerizing, and a potent antibacterial agent active against MRSA.
