The present invention provides a water-soluble modified gum arabic with aweight average molecular weight not less than 0.9 million and arabinogalactanprotein not less than 17% by weight obtained by heating Acacia senegal gumarabic and modified water-soluble gum arabic with a weight average molecularweight not less than 2.5 million and with protein containing high molecularweight components of not less than 25% by weight. Moreover, the presentinvention provides modified gum arabic with standardized and predictablemolecular properties and methods for providing the modified gum arabic endowedwith high emulsification efficiency and stability and for uniforming naturalvariations in unmodified gum arabic. The present invention changes the naturalprotein distribution of gum arabic, and increases AGP content.
