With respect to particle size, the rice flour showed 63 g/100 g
between 60 and 80 mesh and 37 g/100 g above 100 meshes.
The proximate composition (g/100 g) was as follows: 12.88
moisture, 0.27 ash, 7.56 protein, 0.32 lipid and 78.97 carbohydrate.
On a 14 g/100 g moisture content basis, the amylose content was
23.88 g/100 g. The viscoamylographic characteristics were as
follows: initial viscosity (IV) of 0 Brabender units (BU); initial
pasting temperature (IPT) of 66 C; maximum viscosity at constant
temperature (V95), 1460 BU; and final viscosity at 50 C (V50),
1560 BU.
With respect to the amylose content and low gelatinization
temperature, these results are close to the rice flour characteristics
suggested for the production of GFB by Nishita and Bean (1979) and
by Perdon and Juliano (1975). However, they differ from the values
found by these authors with respect to the hot pasting viscosity and
viscosity after cooling to 50 C, which were 750 and 715 BU,
respectively.
