Abstract

Starch esters, (I), of organic acids are prepd. by (i) mixing starch and/or modified starch with a free, non-volatile, organic acid, opt. wih the addn. of a salt of the given acid or with partial neutralisation of acid to salt, to increase mixt. pH and to prevent subsequent starch degradation on heating; (ii) heating the mixt. to 80-180 degrees C after completing esterification. (I) can be used in food industry. Esterification improves freeze-thaw stability and resistance to shear, heat and acid. Unconverted acid can be recovered and re-used, to minimise waste-water pollution.
