Abstract:

The pasting properties of native and octenyl succinic anhydride (OSA) modified waxy corn and rice starches were determined. The two OSA modified starches were separately added to flour in different proportions, and their effects on quickfrozen dumpling wrappers processed were also investigated. The results showed that OSA modified waxy corn and rice starches had higher paste clarity, lower retrogradation and better freeze-thaw stability than their respective native counterparts. Additions of both OSA modified starches could result in increases in flour viscosity and dumpling wrapper hardness, springiness, chewiness (P < 0.05). Dumpling wrappers with 5% pregelatinized OSA modified corn starch had the lowest cold cracking rate and the best sensory quality (eg. colour and lustre, transparency, toughness and mouthfeel).

Key words: octenyl succinic anhydride modified starch, quick-frozen dumplings, cold cracking rate, sensory evaluation
