THESIS

1.3.3 Resistant starch content, starch hydrolysis and glycemic index
Resistant starch content, starch hydrolysis and glycemic index
were examined as described in section 1.2.8 and 1.2.9.
1.3.4 Production yield, color, water activity and moisture content
Production yield, color value, water activity and moisture
content were examined as described in section 1.2.4 and 1.2.5.
1.4 Scaled up production of RS III production from HARS
The scaled up (150 g of rice starch in 850 g distilled water) for RS III
formation was chosen by means of the previous experiment (1.3). The RS III was
produced as described in the above experiment 1.2.1. Comparative study on degree of
hydrolysis, viscosity of the debranched product, degree of syneresis, resistant starch
content, water activity and production yield between small and larger-scale
production of RS III with three replicates of all experiments were performed. Degree
of pullulanase hydrolysis and degree of syneresis were examined as described in
section 1.2.2 and 1.2.3.
1.4.1 Viscosity
The viscosity of solutions was measured at room temperature
(30°C). Before measurement, samples were mixed for 30s before removal of a 1 ml
aliquot for degree of hydrolysis determination and the remained sample was measured
a viscosity. The debranched solutions were placed in 250-mL glass beakers with a 10cm
diameter. Viscosity was measured using a Visco Basic Plus (PoLyvisco,
Kinmatica) with a No. L 3 spindle at a speed of 100 rpm. Viscosity was measured in
cP. Viscosity values were assayed in triplicate.
