Incorporation of quinoa seeds accessions in instant noodles improves their textural and quality characteristics

Abstract

The instant noodles were prepared with incorporation of two Egyptian quinoa seeds accessions to assess the impact of adding quinoa on cooking quality, texture properties, and organoleptic characteristics of instant noodles. Two groups of instant noodles were formulated with substituting wheat flour (72% extract) by quinoa seeds flour from red-colored SHAMS 17-2 and non-colored SHAMS 16 accessions at 10, 20, 30, 40, and 50% (w/w). The physicochemical and functional properties were determined as well as FTIR analysis was carried out. The results showed that incorporation of 10–30% quinoa seeds flour (w/w) in wheat-flour increased total polyphenol content, antioxidant activity, textural parameters, and cooking qualities without influencing the overall acceptability and instrumental color of noodles. The addition of quinoa flour donated to rapid rehydration, advanced cooking loss, water absorption, and amplified porosity. Besides, noodles with 50% of SHAMS 17-2 or SHAMS 16 shifted the FTIR spectrum of each amid in a noodle model, confirming that the phyto-complexes of quinoa seeds interacted with glutenins and/or gliadins amides of wheat flour, thus altering noodles properties. In conclusion, this work provided evidence that the red-colored quinoa seeds might be expended as a partial-ingredient for wheat-flour during instant noodles manufacturing.
