Rice spaghetti extruded at 50:70:80 showed cooking loss of
5.72 g/100 g dry noodles, which is a little bit higher than the
cooking loss of commercial spaghetti (4.78e4.92 g/100 g dry noodle).
The product obtained had a white color and a smooth surface,
and stuck together slightly when cooked. The substitution of rice
flour with DSF and cross-linked cornstarch at 86:10:4 gave the rice
spaghetti a more yellow color, and improved pasta firmness. The
cooked product did not stick together. Texture acceptability of the
product obtained was not significantly different from a commercial
spaghetti product tested. The results showed that rice flour and
defatted soy flour could be used as the ingredients for making rice
spaghetti by an extrusion cooking process. The product obtained is
gluten-free and rich in nutrition from soy flour.
