Rice Noodles: Materials, Processing and Quality Evaluation
233
purchasing decisions are mainly based upon the
preliminary judgment of the noodle quality visually
such as brightness, absence of undesirable specks
and color [97]. The sensory attributes of cooked rice
noodles are appearance, aroma, taste, texture and
overall acceptability [5, 56]. Preference for each
sensory characteristics varies from one consumer to
another; some like raw milled rice and aromatic rice,
others prefer conventional rice or the parboiled rice
[98].These properties are significantly influenced
by using various varieties of rice for noodle
production. The sensory properties of final noodle
products are evaluated by trained sensory panels
[5]. The most important quality factors in this
regards are texture and color of final product [15,
99]. Consumers mostly prefer hard and non-sticky
noodles which are influenced by the flour amylose
concentration [5, 15, 99]. The sensory attributes
of cooked rice noodle is also influenced due to the
variation in flour particle size (Table 6).
The important factor in the evaluation of rice
noodle product is appearance. The appearance of
noodle manufactured from rice flours exhibited
variations, which is credited to the presence of
natural pigments, i.e., polyphenols and carotenoids
[100]. Color is the most important parameter used
for evaluating the visual quality and is important
for better marketability of noodles. Fresh noodles
must maintain white colored appearance [101].
Appearance is also influenced by the interaction
of starch and protein. As the interaction between
protein and starch is weak, it gives opaque
noodles. An increase in ash concentration also
affects negatively the appearance of noodles.
As ash concentration of the final noodle is less,
it gives transparent product [102].The sensory
