Process to stop the growth of thermophilic microorganism in an aqueous sugar containing medium

摘要

Thermophilic microorganisms are inhibited in sugar contg. aq. medium (A) by treating with a hop-derived additive (B) at 50-80 degrees C. (B) is any suitable hop product, partic. a dissolved or emulsified hop extract, but may also be a solid, e.g. dried or pelleted hops, or brewery waste, e.g. yeast contg. hop residues or spent hops. Pref. sugar beet or cane are thermally extracted in presence of (B) which may be added in liq. dissolved or emulsified form to the hot extract soln. Alternatively the plant material to be extracted is treated with a solid (B). Addn. of (B) may be continuous or periodic.
