| Abstract: | Alkaline salt confers unique characteristics to noodles. Polyols and emulsifiers
can be used to improve noodle quality and prolong their shelf life. However, there is no
information regarding the effect of alkali in combination with polyols and emulsifier on
the properties of noodle dough. This research aimed to study the effects of emulsifiers
[lecithin and distilled monoglycerides (DMG)] and polyols (glycerol and sorbitol) with or
without sodium carbonate on the thermal properties of gluten-free noodle dough during
gelatinisation and retrogradation analysed by DSC. Results showed that the addition
of alkali increased gelatinisation temperature of noodle dough (pH ~10). The effect of
incorporating either emulsifier or polyols on gelatinization temperature was significant in
a neutral system compared to an alkaline system. The control presented the lowest onset
temperature to melt retrograded sample, indicating a less crystalline arrangement. Noodle
dough in neutral pH had both type I and II ALCs, while alkaline noodle dough presented
only type I ALCs. All retrograded samples presented only type I ALC. Polyol significantly
decreased ALC formation. In conclusion, alkali had a significant effect on gelatinisation
properties and proved effective in preventing the formation of crystals in starch containing
DMG after cold storage. |
