Abstract:
This study dynamically monitored the effect of fructose concentration on the processing properties and structural transformation of starch noodles during production. With increasing fructose concentration (0-8 %), G', G", and hardness of starch dough decreased, while pasting temperature rose, and breakdown and setback value decreased. During heating, fructose increased Tp (from 49.22 °C to 52.99 °C) and XRD crystallinity (from 1.29 % to 3.58 %) of starch gels. During cooling, fructose increased the heterogeneity, short- and long-range ordered structure of retrograded starch gels, indicated by increasing melting temperature range, melting enthalpy (from 1.17 J/g to 1.83 J/g), R1047/1017 (from 0.564 to 0.585), and XRD crystallinity (from 2.66 % to 6.31 %). Starch gels with 5 % fructose showed highly packed crystalline lamellae. For noodles, 5 % fructose yielded smoother appearance, higher acceptability, lower adhesiveness, and less merging than 2 % or 8 % fructose. These findings potentially highlight fructose could enhance the processing performance of starch noodles containing cassava starch.
