This work aimed to evaluate the viability of adding soybean flour to wheat flour for cake making by quantifying product acceptance using affective sensorial tests, principal analysis components and internal preference map. Four cake samples with wheat flour replaced by concentrations of 45% and 75% of soybean flour made of different soybean varieties (conventional and without lipoxygenase) were evaluated. The cakes were evaluated by consumers using a structured hedonic scale of 9 points. All samples obtained grades above the cutoff point (6.0). The samples made of improved flavor soybean flour were the best accepted. The results showed that the use of soybean flour as a partial substitute for wheat flour is a viable alternative, constituting an aggregating source of nutritional quality in food making.
