The effect of incorporation of red lentils flour on the quality of non-fried instant noodle / Ili Fatimah Ismail

The aim of this study was to develop non-fried instant noodles in which lentils flour
was added at 10, 30 and 50 percent levels. The products were compared to a control
noodle (100% wheat flour). It was observed that the protein, ash and moisture
content increased significantly (p<0.05) when the level of lentils flour was increased.
There was no significant difference (p<0.05) between all samples for fat and crude
fiber content. The lightness (‘L’ value) and yellowness (‘b value) decreased
significantly (p<0.05) when the level of lentils flour was increased. In the other
hand, the redness (‘a’ value) was increased significantly (p<0.05) when the level of
lentils flour was increased. The firmness increased significantly (p<0.05) with lentils
flour level and was evidenced by both instrumental analysis and quantitative
descriptive analysis (QDA). The QDA showed that the perception in overall
appearance, elasticity, smoothness, overall texture and overall quality increasingly
deviate from the control with increased addition of lentils flour. However,
yellowness, firmness and after taste were increased with increasing lentils flour into
non-fried instant noodle. The incorporation of red lentil flour noodles with 10%
lentils flour level was considered to be as acceptable as the control for overall quality
and taste on hedonic scale rating given by panelists.
