The objective of the research was to compare the sensory profiles generated by two sensory evaluation methodologies: Check-All-That-Apply (CATA) and Flash Profile (FP) in purple corn (Zea mays L.) - INIA 601, quince (Cydonia oblonga), cinnamon (Cinnamomum verum), and cloves (Syzygium aromaticum) with stevia leaves (Stevia rebaudiana) with consumer judges. The formulations, expressed in percentages of crown: quince: cinnamon: cloves: stevia, A and H (100:0:0:0:0); B and I (48.9:39.2:8.3:3.3:0.3); C and J (83.6:4.5:8.3:3.3:0.3); D and K (63.3:24.8:8.3:3.3:0.3); E and L (53.4:42.7:0:3.6:0.3); F and M (91.2:4.9:0:3.6:0.3); G and N (69.1:27.0:0:3.6:0.3), were prepared in 250 mL of water (100 °C) with a rest time of 10 and 5 min. The FP highlighted 300 sensory descriptors distributed in color (148), taste (199), smell (43) and texture (10). The sensory profile was for formulation B: taste (sweet, stevia, quince, fruity) and smell (fruity); for J: color (purple) and flavor (“chicha morada”); while for I: flavor (sweet, stevia, quince, fruity) and smell (fruity). The CATA methodology, using 12 sensory descriptors generated in the PF, characterized sample B as flavor (fruity, sweet, stevia), color (reddish) and smell (fruity), J as: flavor (“chicha morada”, quince), and sample I as: flavor (fruity, sweet, stevia), color (reddish) and smell (fruity). The Generalized Procrustes Analysis (GPA) for the FP data and the Correspondence Analysis (CA) for the CATA data in the first two dimensions; explained 68.6 and 90.47 percent of the total variance, respectively; obtaining a good connection between FP and CATA (vector connection coefficient Rv = 0.89 and p-value <0.05), showing that both methodologies were useful to analyze sensory characteristics. Finally, the most liked samples were I, B, D, K and J, which were located near areas where the percentage of consumer judges who scored their general taste high was 90, 90, 80, 80 and 80 percent respectively. Achieving the objective of comparing the sensory profiles generated by the sensory evaluation methodologies: Check-All-That-Apply (CATA) and Flash Profile in the filters.
