Profoam (PGA 511)

Beer Foam Stabiliser

Profoam 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 both the ideal blend of seaweed species required to yield alginic acid of the necessary quality, and to optimise the critical esterification stage. The resulting Profoam is free from the technical problems associated with the less technically refined products on the market.

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

• Profoam is a well accepted brewing aid used extensively throughout the world.
• Beer treated with Profoam has characteristic attractive foam, which is maintained even under less than ideal serving conditions.
• Profoam is supplied in standard 20 kgs sacks, which incorporate in their make-up an ingenious aluminium layer which prevents contamination from external taints.
