variety, processing factor, amylose concentration
and gelatinization temperature [5, 9]. On a 9-point
hedonic scale, the sensory liking scores cooked rice
noodle in term of texture ranged from 3.11 to 6.92
[5, 13, 55]. Wang et al. [104] found that rice noodle
scored highest in case of hardness, while lowest
score in case of slipperiness. The mean scores of
native rice noodles as well as their blends with
wheat flour differed significantly in regard to texture
[56]. Rice noodles made from the incorporation of
wheat flour in a considerable amount give desirable
texture [56]. Similarly, Inglettet al. [48] found
similar trend in noodles prepared from blend of
rice and wheat flour. Texture is the main quality
factor that determines consumer preference for the
cooked noodle [105]. High quality noodle must be
neither too hard nor too soft [22, 57]. Texture of
rice noodle is also affected by particle size. The
acceptance rate of noodles made from flour of
small particle size was more as compared to the
flour of large particle size [13]. Muhammad et al.
[106] evaluated the stickiness, elasticity and taste
of cooked rice noodles by twenty trained panelists.
The noodle stickiness was judged by testing the
adherence of the noodles to the tongue. While the
noodle elasticity was evaluated by stretching the
noodle strands until they break. The reduction in
firmness is due to the lower level of protein in rice
noodle as compared to wheat based noodles [107].
Generally, rice based noodles have soft, and sticky
texture with lower elasticity [22]. Firmness is the
main factor in representing the texture of cooked
noodles [1, 5].
The overall acceptability of rice noodles
depends upon appearance, aroma, taste and texture.
Various researchers have found differences in the
desirability and acceptance of rice based noodles.
Overall acceptability score values of rice noodles
on 9-point hedonic scale were in the range of 2.7 to
7.02 [5, 13, 55]. Rice noodles blended with wheat
flour showed maximum acceptance scores [35, 66].
Thomas et al. [14] studied the sensory acceptance
rate of Bario and Basmati rice noodles. Bario rice
had a higher acceptability score of 6.67 compared
with Basmati rice (4.8). In term of appearance and
overall acceptability, noodles made from Bario rice
were ranked higher as compared to Basmati rice
noodles. It was observed that panelists usually give
preference to firm noodle irrespective of the aroma
[5]. The cooking loss of rice noodle negatively
correlated with the sensory properties of noodles
[71]. Maximum cooking loss causes turbidity in
cooking water; thereby decreases cooking tolerance
and mouth feel [56, 82]. It was observed form the
previous literatures that variation in genetic makeup
of rice as well as flour particle size contribute
important role in final noodle acceptance [5, 13].
