Abstract
Precise control of hop aromatic flavors and hop bitter acids in beer is achieved by adsorbing these hop flavors on fumed silicon dioxide and dosing the fumed silicon dioxide containing adsorbed hop flavor into beer, preferably after suspending the fumed silicon dioxide containing the adsorbed flavors in an aqueous medium. The hop flavors are desorbed in the beer and fumed silicon dioxide solids become available as a clarifying agent and are subsquently filtered from the beer.
Claims12
A composition useful for admixing with beer prior to final filtration consisting essentially of fumed silicon dioxide which contains adsorbed thereon between 0.015% and 35% w/w of hop oil or a mixture of hop oil and a hop flavor constituent selected from the group consisting of an iso-alpha acid and a non-acidic hop resin.
A composition consisting essentially of an iso-alpha acid and hop oil adsorbed on fumed silicon dioxide.
A composition consisting essentially of non-acidic hop resins and hop oil adsorbed on fumed silicon dioxide.
A composition consisting essentially of a hop oil adsorbed on fumed silicon dioxide.
A composition consisting essentially of a mixture of at least one of propylene glycol, glycerine, and ethanol with a hop oil, said mixture being adsorbed on fumed silicon dioxide in an amount of at least some and up to about 20% by weight of hop oil per total weight of composition.
A process for introducing hop aromatic flavor into beer which comprises the steps of admixing hop aromatic flavor including hop oil with fumed silicon dioxide to adsorb said flavor thereon, dosing the beer following fermentation with said fumed silicon dioxide containing hop aromatic flavor including hop oil to release said flavor and to clarify said beer, and thereafter subjecting said beer to filtration for removal of fumed silicon dioxide solids from said beer.
