Drifoam

Protects beer foam

Overview

Drifoam is a powder form of propylene glycol alginate produced by the esterification of alginic acid. It is designed to give a trouble free method ofenhancing and protecting beer foam. Many years of development have been undertaken to identify both theideal blend of seaweed species required to yield alginic acid of thenecessary quality, and to optimize the critical esterification stage.The resulting Drifoam is free from the technical problems associated withthe less technically refined products on the market.

Principle

Drifoam stabilizes beer foam in two ways. Firstly by actively interacting with foampositive, hydrophobic beer polypeptides, and secondly by reducing the impact offoam negative factors.This latter effect explains the positive role Drifoam also plays in protecting beer foamfrom external contamination, particularly from grease and detergents.
