Water solubility index (WSI)
The WSI of brans was determined by slight modification of
the method described by Anderson et al. (1969). Samples
(2.5 g) were dispersed in 30 mL of distilled water, using a
glass rod, and cooked at 90 °C for 15 min in a water bath.
The cooked paste was cooled at room temperature and
centrifuged at 3,000 g for 10 min. The supernatant was
decanted for determination of its solid content into a tarred
evaporating dish. The weight of dry solids was recovered by
