Ice Crystal Control
Tara gum acts as a highly effective cryoprotectant by binding free water and increasing unfrozen phase viscosity, preventing large ice crystal formation throughout shelf life.
Heat Shock Protection
Among galactomannans, tara gum provides outstanding heat shock protection — superior to LBG. During distribution temperature fluctuations, it keeps texture smooth and consistent.
Mouthfeel
Tara gum imparts a rich, buttery mouthfeel without the gummy texture of guar gum. It provides clean, short-textured palate feel ideal for premium ice cream.
Meltdown Control & Overrun
Tara gum maintains structural integrity during melting, preventing rapid collapse. It contributes to good 'overrun' — the air incorporation that gives ice cream its light structure.
Formulation
Typical usage: 0.05–0.30%. A standard recipe uses 0.15% tara gum + 0.02% kappa-carrageenan + 0.30% emulsifier. Compatible with HTST pasteurization (80°C for 20–30 seconds).
