Following is the molecular structure of  Locust bean gum (9000-40-2) is:

 Locust bean gum (9000-40-2) specifically retards ice crystal growth by forming structured gel at solid/liquid interface This particularly occurs on freeze-thaw cycling, which encourages the frustrated crystallization of the galactomannan so causing the gel to form. It encourages phase separation with skimmed milk powder showing synergistic viscosity with casein and becoming slightly thixotropic on forming a biphasic system containing casein micelles within a polysaccharide continuous network. To aid this it may usefully be combined with xanthan ,with which it shows viscosity synergy, and k-carrageenan to super helices of which it adsorbs.
