Hydroxypropyl starch (E1440) is a modified starch produced by reacting native starch with propylene oxide. The hydroxypropyl substitution reduces retrogradation, lowers gelatinization temperature, and improves freeze-thaw stability. LUXI Chemical tailors the degree of substitution (MS) to meet specific application requirements.
