4.4. RS and starch thermal properties
Increases in gelatinisation temperature at the mid germination
stages (3e5 days) (Fig. 5) might be due to the increased amount of
sugar or reduced sensitivity of the measurement caused by a lower
concentration of starch, as reported in other common rice cultivars
(Wu et al., 2013). Other than these potential reasons, an increase in
gelatinisation temperature after 4.5 GD in R7954 might be due to
increased microcrystallinity (data not shown). Increased ranges in
melting temperature in R7954 at 10.5 GD might be interpreted as
an increase in heterogeneity of starch crystallinity and less cooperative
melting between amorphous and crystalline regions (Bao
and Corke, 2002).
It has been reported that the biphasic endotherm could be
deconvoluted into two components and low-temperature
