RAPID COMMUNICATION: Studies on preparation of starch succinate
by reactive extrusion (in English)
Polimery 2004, No 2, 132
Reactive extrusion was applied to obtain the starch succinate. Esterification using succinic anhydride was performed using PTW16/25D twin-screw extruder. Natrium hydroxide solution or natrium bicarbonate were used as catalysts. The influence of three kinds of starch was studied. The starch ester with degree of substitution (DS) higher than 0.6 was obtained from potato starch in the presence of NaOH solution.
