How do gums build viscosity?
o Build viscosity by interacting with watero Hydrogen bonding with water molecules
![Page 3: Using Gums in Cake & Batter Systems](https://reader033.vdocuments.us/reader033/viewer/2022051520/58a9fce81a28abec248b55c5/html5/thumbnails/3.jpg)
Why use gums in cakes?
o Thicken and stabilize batter o Hold batter emulsion
o Result in an even, consistent crumb structure
o Suspend inclusions

Why use gums in cakes?
o Manage watero Increase water-holding capacity, leading to a
moister and lighter mouthfeel and decreased particulate awareness
o Impart freeze/thaw stability
o Increase shelf-life
o Effective at very low usage levelso 0.1–0.3% based on flour weight

Creating Batter Balance
Batter Stability
Ingredient Levels
Batter Viscosity
• Batter Stability• Stable emulsion ensures
a tight, consistent crumb• Batter Viscosity
• Batter not too thick ortoo thin
• For dispensing and suspension
• Ingredient Levels• Balance between water
and gum levels

Considerations When Formulating Batter Systems
o pH – neutral to alkaline
o Mixingo Medium shear and short time
o Temperatureo Ambient temperature during mixing
o High internal temperatures during baking
o Variable ingredients

Gum Combinations Add Functionality
o Cellulose gum/Xanthan gum combinationo Less likely to impart gumminess
o Guar gum/Xanthan gum combinationo Synergistic relationship for increased thickening
o Gum Arabico Natural emulsifier and film-former
o Alginateo Reactive with calcium

Control – no gums
An acceptable cake can be achieved without gums, however, moistness, softness of crumb and volume can all be increased by adding gums.

Tips for Gluten-Free Cakes
o In general, gluten-free batter is thinner
o Same gums can be usedo Higher usage levels, 0.25–0.5% based on flour
weight
o Guar gum may be limited due to flavor
o Added water is less than conventional cakeso 5-10 parts added water for every part gum
