AB Vickers process additives

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 of enhancing and protecting beer foam.

  • Many years of development have been undertaken to identify the ideal blend of seaweed species required to yield the right quality of Alginic acid, and to optimise the critical esterification stage.

    Drifoam stabilises beer in two ways:

    • Firstly by actively interacting with foam positive hydrophobic beer polypeptides
    • Secondly by reducing the impact of foam negative factors.

    This latter effect explains the positive role Drifoam plays in protecting beer foam from external contamination, particularly from grease and detergents.

    Drifoam is supplied in standard 20kg sacks which incorporate in their packaging an ingenious aluminium layer which prevents contamination from external taints.
