ARABINOL® Multinstant SB is a highly refined, micro-granulated gum arabic for improving head retention. Derived from Acacia senegal, its instantly soluble polysaccharide matrix enhances mouthfeel and body and head retention, key attributes for beer quality and consumer appeal. Five times more concentrated than traditional liquid gum arabic. 

Key Technical Benefits and Mechanisms

Bench-Top Validation: ARABINOL® Multinstant SB in a European Lager

To visually demonstrate the functional impact of ARABINOL® Multinstant SB on foam retention, a simple bench-top trial was conducted using a commercial European-style lager (330 mL, 4.8% ABV). Two samples were prepared:

  • Left glass: Control (no additive)

  • Right glass: Treated with ARABINOL® Multinstant SB at 20 mL/hL

The same base beer was poured simultaneously into both glasses, and photos were taken at 3 key time points to document foam performance over time:

Figure a) Immediately after pouring
Figure b) 1 minute after pouring
Figure c) 3 minutes after pouring

This bench-top trial illustrates the clear functional benefit of ARABINOL® Multinstant SB in improving foam stability under real brewing conditions. When added at a dosage of 20 mL/hL to a standard European-style lager, the treated sample consistently retained a more stable and lasting foam head compared to the untreated control. The visual difference became increasingly apparent over time, with the control beer showing significant foam collapse after just one minute, while the ARABINOL®-treated beer maintained its structure and sensory appeal. These results support its application in styles where foam quality is essential for consumer perception.

Best Practices: When to Add ARABINOL® Multinstant SB

For optimal results, ARABINOL® Multinstant SB should be dissolved in beer and then added directly to the Bright Beer Tank prior to packaging, seamlessly integrating into your production process without additional steps or equipment.

Early addition (e.g., during fermentation or filtration) is not recommended, as the product may be removed or its effects diminished during clarification or processing. To ensure uniform distribution, the product should be fully dissolved in water and added with proper mixing. Because it is a preservative-free organic polysaccharide, the prepared solution must be used immediately after preparation to avoid microbial growth or degradation.

Foam Stability Over Time With ARABINOL® Multinstant SB vs Without

Below is a comparison of foam stability over time in standard brewing conditions, showing the difference between using ARABINOL® Multinstant SB and not using it.

The data presented in this chart is not extracted from formal control trials using ARABINOL® Multinstant SB. It is based on documented functional properties of gum arabic from academic literature and its known effects on foam retention and mouthfeel in beverage applications.
