Odor-induced taste enhancement in Mexican adults with obesity and normalweight Odor and taste play an important role in flavour perception and it is well known that the chemical composition of the matrix and consequently its structure influences release and perception of flavour. OITE (Odor-induced taste enhancement), is a phenomenon that derives from the integration of taste and odor into flavor perception in order to enhance the taste perception.In this work, the OITE phenomenon was used to enhance the sweet and salty taste in people of normal weight (PN) and with obesity (OB) using ranking tests. In addition, pleasantness, familiarity and JAR scale was applied with solutions with odorant. Moreover, participants filled out two questionnaires on eating behaviour (DEBQ & DFS). Thirty-nine people of normal weight (PN: 25 kg/m 2 < BMI) and thirty-five obese people (OB: BMI ≥ 30 kg/m 2 ) participated in sensory evaluations which were divided into two sessions; sweet session and salty session. For the sweet part, the participants evaluated two bases; Jamaicas water and apple juice.The "vanilla mx", "golden syrup" and "sugar type" odorants were added to the Jamaica water base and the "vanillin fr" odorant were added to the apple juice base. In the case of the salty part, the participants evaluated three bases; the chayote, corn and green peas with the odorants "mx bacon" and "Beff" to the chayote base, odorant " onion fried" and "coriander" to the white corn base and odorant "bacon fr" for the green pea base. Each ranking was performed with 4 solutions, 3 with increasing salt/sugar concentration (S1 to S3), and the fourth contained the lowest sugar/salt concentration with an odorant added. The participants had to classify the 4 bottles according to the intensity of sweetness or saltiness. The results showed that people with obesity (OB) experienced a slight tendency to perceive a higher odor induced sweetness enhancement than normal weight people (NW). In contrast, people with normal weight showed a slightly higher trend to perceive odor induced saltiness enhancement than obese people.
