HOP ACIDS INHIBIT BACTERIA GROWTH
Hops have a long history of use as a natural preservative in beer. A little known benefit, however, is that hops also contain high concentrations of unique “alpha” and “beta” acids that can inhibit the growth of Gram-positive bacteria at surprisingly low concentrations. To that end, Hopsteiner produces a variety of natural and modified food grade hop products which can very effectively and economically inhibit bacteria growth in a wide variety of applications including food, spirits, fuel ethanol, yeast and process streams (to name just a few).
