HOW TO USE GUMS By John D. Keller, Jr.

HOW TO USE GUMS 1. Dispersion 2. Dissolution Placing Gums In Solution is a Two Step Process: 1. Dispersion 2. Dissolution “The most difficult step comes first”

Dispersion and Hydration “Importance of Doing Correctly” Optimum Gum Performance Full Gum Functionality Avoid Processing Problems & Frustration Save Time & Money

Proper Agitation (High Shear) Mechanical Assistance Methods of Dispersion Non Solvent Dry blend Proper Agitation (High Shear) Mechanical Assistance Optimize Particle Size Restructure Particle Size

Non Solvent Gum Non Solvent Oil *Corn Syrup (High Brix) “Gone” H2O

The Pre-Solution Method Gum 5% Solution 10% Aliquot 0.5% Solution

Dry Blend Sugar Gum 1. Keeps Gum Particles Separate 2. 10 : 1 Ratio (Minimum)

Proper Agitation (High Shear) High Speed Vortex Correct ! Low Speed Vortex Wrong !

Do’s & Don’ts of High Shear Dispersion Maintain Good Vortex Add Powder: Slowly & Separately Keep Stirring Add Powder Too Quickly Incorporate Air (Cavitation) Avoid Low Shear/Small Particles ( Problems )

Mechanical Assistance (Eductor Funnel) Gum Funnel Water Inlet High Speed Stirrer

Use of Gums: Dispersion & Hydration "Optimize Particle Size" Gum Particle Size Ease of Dispersion Speed of Hydration Coarse Mesh: Easy Slow Agglomerated* Regular Mesh Fine Mesh Fast Difficult * Exception to the rules

Restructure Particle Size “Agglomeration” + H2O Difficult To Disperse Easy To Disperse Easy To Hydrate
