The present invention provides a water-soluble modified gum arabic with a weight average molecular weight not less than 0.9 million and arabinogalactan protein not less than 17% by weight obtained by heating Acacia Senegal gum arabic and modified water-soluble gum arabic with a weight average molecular weight not less than 2.5 million and with protein containing high molecular weight components of not less than 25% by weight. Moreover, the present invention provides modified gum arabic with standardized and predictable molecular properties and methods for providing the modified gum arabic endowed with high emulsification efficiency and stability and for uniforming natural variations in unmodified gum arabic. The present invention changes the natural protein distribution of gum arabic, and increases AGP content.

Ispaghula (material from the plantuseful as an agent in relieving constipation, is subjected to treatment with -radiation at a dose of up to 13 kGy, and preferably in the range 5-10 kGy. As well as effecting sterilisation of the ispaghula, this dose of irradiation has been shown to offer surprising rheological advantages.

Irradiation of ispaghula

Disclosed are modified naturally occurring biocompatible biopolymers of plant and animal origin made by subjecting same to ionizing radiation in the presence of a mediating gas, typically acetylene to enable one to selectively enhance and modify one or more of the physiochemical properties of the starting materials which have a wide range of uses in medicine, food technology and other industrial applications. Notwithstanding the modifications, the biocompatibility of the biopolymer remains unchanged and no new or additional functional groups are introduced into the starting biopolymer.
