Description
What Is Locust Bean Gum?
- Source: Endosperm of Ceratonia siliqua(carob tree) seeds.
- Chemical identity: Galactomannan polysaccharide composed of mannose and galactose units.
- Appearance: Off-white to light brown powder.
- Solubility: Requires heat for full hydration; synergistic with other gums.
Key Benefits
- High viscosity: Thickens aqueous systems effectively at low concentrations.
- Synergistic gelling: Forms elastic gels when combined with xanthan gum or carrageenan.
- Freeze-thaw stability: Enhances texture and prevents syneresis in frozen products.
- Clean-label: Plant-derived and widely accepted in natural formulations.
- Low flavor impact: Neutral taste, ideal for delicate flavor systems.
