One interesting use of gellan gum in food preparation is in gastronomy, especially to create specialty desserts.
Chefs sometimes add gellan gum to ice cream and sorbet recipes to help with churning, plus it helps prevent melting of cold desserts when a flame or alcohol is used to provide browning or crusting (such as to make creme brulee, flaming sorbet or bananas foster).
