P. Tomasik et al., FACILE ROUTE TO ANIONIC STARCHES - SUCCINYLATION, MALEINATION AND PHTHALATION OF CORN STARCH ON EXTRUSION, Starke, 47(3), 1995, pp. 96-99
Corn starch can be acylated on extrusion with succinic, maleic and pht
halic anhydrides as well as with butane tetraioic dianhydride in the p
resence of carbonate buffer. Such reaction mixtures containing 30% moi
sture gave highly hydrophobic products of low or moderate water bindin
g capacity.
