Abstract

Chemical modification of TZL-COMP4 hybrid maize starch was carried out to produce the acetylated (ACE), oxidised (OXI) and acid-thinned (ATI) derivatives. The functional, pasting and morphological characteristics of the native (NAT) and modified starches were determined. The results of functional properties of the starches showed that swelling power and solubility at 55 °C – 95 °C ranged from 174.70±12.27 – 956.04±101.07 g/100g and 0.21±0.12 – 0.58±0.01 g/g, respectively. Oil and water absorption capacity, gelation properties and light transmittance ranged from 214.44±0.02 – 518.57±0.26 g/100g, 10 – 14 %w/v and 6±0.03 - 73±0.10, respectively. Significant (p < 0.05) reduction in pasting temperature was observed in ACE and reduced susceptibility to retrogradation was observed in ATI. Granule morphology showed small granules with no disrupted surfaces.
