Other Grafted Cassia Seed Gums

Many other Cassia seed gums have been modified and the properties of the grafted seed gums, such as the viscosity of the gum solutions, and saline and water retention, have been studied to explore the possibility of their exploitation.

The Cassia angustifolia GaM possesses the potential to become a new source of commercial gum due to its high content in the endosperm (about 50%) and its valuable rheological properties. It was suggested, in a similar way as for other GaMs, for usage as an additive in pharmaceutical formulations [188, 246]. Also the Ipomoea seed gum in its natural form, and after modification by grafting, has the potential to be used as a commercial gum [178]. 

This seed polysaccharide has been grafted with acrylonitrile under micro-wave (MW) irradiation without adding any radical initiator or catalyst [46] as needed by other Cassia gums. Various properties of the MW synthesized grafted gum such as water/saline retention, water retention after saponification, and viscosity of the gum solutions have been compared with the conventionally synthesized grafted gum and the parent gum.
