Innovative clarifier for vegan beers06 Dec 2018 Lallemand Brewing’s Protofine is a natural, plant-derived formulation (based on pectin) with application potential in a wide range of alcoholic beverage applications. The active components of Protofine have been widely used throughout the food industry for many decades. Protofine is comparable to traditional fining products (isinglass) in performance. Protofine should be dissolved and added as an aqueous solution, during transfer of beer from fermenter to cold storage tank. The same preparation and dosing tank used for traditional fining product can be used for Protofine.
