Noodles were prepared by incorporation varying blends (0, 20, 40, 60 and 80%) of rice flour in replacement of wheat flour. Noodle samples were evaluated for their proximate composition, scavenging activity, sensory properties and cooking quality characteristics. The proximate composition of uncooked noodles varied significantly, with increasing rice flour level that replaced wheat flour , a gradual decreases in moisture , ash , crude fiber and protein contents in noodle pastes were occurred , their values ranged between 4.02-5.33% ; 1.11-5.22% , 0.65-0.82% and 8.51-12.81% ,respectively. However, an increases in fats, total carbohydrates and energy value were take place ranging between 4.62-8.91 % , 71.11-76.74% and 377.64 - 421.43 kcal/100g, respectively .The antioxidant activity ranged between 22.2% for wheat based noodle (100% wheat flour) to 36.8% for sample containing 80% rice flour as scavenging activity for free radicals. The overall acceptability of wheat-based noodles (WF: RF 100:00) were rated superior for their sensory preferable characteristics. Among the blended flour noodles, the noodles incorporated with up to 40% rice flour received the same acceptability as wheat-based noodle. The cooking quality characteristics differed significantly among the noodle samples; the cooking time ranged from 6.5 to 10.3 min, it was more in wheat-based noodles than noodles from rice flour. Cooking loss; water absorption percent; cooked weight and swelling index values ranged from 0.1 to 0.6%, 137.1 to 231.6%, 23.74 to 33.24 g/g and 3.20 to 5.38 %, respectively; which revealed that a significant hindered was occurred in the functional paste properties and cooking quality parameters with increasing the level rice flour in noodles. The study indicated that, noodles prepared from mixtures of wheat and rice flour showed that the best acceptable sensory attributes and cooking quality characteristics were observed at blending ratio 40 : 60% rice flour : wheat flour . These findings enhance the utilization of non- conventional flours like rice flour for the development of value added noodles with reduced gluten content and boost nutritional value.

This study was carried out to investigate the effect of partial substitution (5, 10 and15%) of wheat flour (72% ext.) by whole meal quinoa flour (QF) on quality parameter of pan bread. QF contained the highest percentage of protein, Lipids, ash and crude fiber. Also, QF contained the highest amount of essential amino acids such as (threonine, methionine, lysine and histidine). From the results, it could be seen that, water absorption and degree of softening increased by increasing the substitution levels, but stability, resistance to extensions and energy of dough decreased. The addition of QF adversely affected on the specific volume of pan bread. The lightness (L*) and yellowness (b*) of pan bread decreased, but redness (a*) increased gradually by increasing QF. Evaluation of the organoleptic properties of pan bread revealed that no significant differences (P≥0.05) between control sample and bread samples contained QF for taste and summitry form. The bread contained QF had higher score for crust color, pore size and overall acceptability than control sample. Hardness (g) of pan bread increased and springiness decreased gradually during storage of bread at (25˚c ±2). The rate of staling of bread contained QF lower than control sample. Gluten – free biscuit made from 100%QF contained the highest percentage of protein, lipids, ash and crude fiber compared to that of corn and rice – quinoa composite flour. The addition of corn and rice flour adversely affected on the thickness, diameter and  spread ratio. The highest spread ratio was noticed in the biscuit made from 100% QF. It is worth mentioning that the biscuit made from 100 % QF or that of corn and rice – quinoa composite flour gave the biscuit with sensory acceptable. On the other hand, it could be noticed to that the biscuit contained high level of quinoa flour was darker in compared to another samples.
