Effects of Particle Size of Rice Flour on Textural Properties of Rice
Noodle
Figure 4.18 shows the effect of particle size of rice flour on resistance to compression of
noodle. It was found that rice flour with smaller mean particle size gave noodles with more
surface firmness or resistance to compression. The results correlated with the results of
Hatcher, et al. (2002) who found that resistance to compression of cooked wheat noodle
produced from flour with smaller mean particle size (85μm) had higher resistance to
compression than that of larger particle size (110 and 132μm). As mentioned in section
4.2.2, gel of rice flour with smaller mean particle size had higher elasticity than that of flour
with larger particle size. This means that gel from flour with smaller mean particle size
behaved more like solid and had more resistance to break down than gel from flour with
larger particle size and resulted in more surface firmness of noodle.
