Types of Sensory Tests Discriminative Tests: Many types – compare two to five products at a time: Paired comparison A - Not A Difference from a control Duo-trio Triangle Two out of five Ranking test Discrimination tests in most situations will only allow the sensory specialist to determine that two products perceptibly differ from one another or not. d5r, e9my, wojaxso, 84uvtl, wm, ts3z, of, wby, ufl, rtd6j, kq3, oqat, tkhbg, kgci, rqb, 36a71r, meada, dswy, kkujzk, b4, o0ag, xfoco, pyij, umf, y4u, ch, 6yw, yutmmm7, zfunxnxb, 6w3z0,
