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.
