Molecular Architecture
Linear backbone of (1?4)-�-D-mannopyranose with a-D-galactopyranose side chains via (1?6) linkages. MW: 1,000,000�2,330,000 daltons.
The Critical 3:1 Ratio
Guar = 2:1 (34% galactose): best cold solubility, limited synergy. Tara = 3:1 (25%): good cold solubility + strong synergistic capability. LBG = 4:1 (20%): best synergy, poor cold solubility.
Tara's Optimal Position
Sufficient cold-water solubility, strong synergy with kappa-carrageenan and xanthan, high viscosity generation, excellent freeze-thaw stability � best of both worlds.
FTIR Confirmation
Characteristic bands for �OH stretching (3393�3442 cm?�), sugars including galactose, and C=O/C�O bonds confirming polysaccharide structure. These groups drive water-binding and film-forming abilities.
