Description

Nora Haring, Milan Chňapek, and Blažena Drábová study how extraction choices change the yield of prized compounds from hops, in a paper from 2025. Hops carry a class of compounds with strong antioxidant effects. Three of them are tracked here, including xanthohumol.

The team varied the solvent, the extraction temperature, and how the hops were ground. Ethanol pulled out more of the compounds than methanol. Grinding the hops while frozen greatly raised the release of all three. Each compound peaked at its own temperature, from moderate heat to the top of the range. Statistical tests confirmed that each factor, and their interplay, mattered. The paired method gives a base for standard hop extracts.
