Evaluation of Subabul (Leucaena leucocephala) Seed Gum as a Wet-end Additive in Paper Making

Leucaena leucocephala is uselul not only due to its food, fodder and fuel value but also due to the gum exuded by it as a result of gummosis which was found to be comparable with guar gum as Wet-end additive in paper making. Subabul seeds which are abundantly available have no commercial utilization till todate. Studies conducted in this laboratory has shown that seed is a rich source of gum. The gum is found to be readily soluble in waler and tested as an additive in paper making.
