In this study, physicochemical and sensory characteristics of wheat chips enriched with different legume
flours were investigated. Wheat chips formulations were composed with the mixture of wheat flour and
the mixture of three different legume flours (wheatelegume ratio 80:20). Mixture design approach was
used to determine the effect of interactions between pea, chickpea and soy flour on the physicochemical
and sensory properties of chips produced with wheatelegume flour mixture. In addition, product
optimization was carried out by using ridge analysis to determine the optimum legume flour mixture
proportions based on sensory properties of chips samples. Chickpea flour was found to be highest
desired component depending on the general acceptability scores of chips. Protein content of chips
increased significantly with the addition of soy flour. Optimum limit values of chickpea, pea and soy flour
in the legume flour mixture used for the enrichment of the wheat chips were found to be 50e100 g/
100 g, 0e60 g/100 g and 0e45 g/100 g legume flour, respectively, with respect to sensory properties.
Additionally, ridge analysis results showed that the wheat chips should include only chickpea flour in the
legume flour fraction to obtain maximum overall preference score (6.08)
