    Tequila is one of the emblematic beverage of Mexican culture. In recent years, tequila consumption has increased, in that sense it is necessary to have quality control that ensures constant quality. In that sense, sensory evaluation can be a tool to contribute to this. In addition, consumer science can contribute to the study and understanding of the factors that influence the choice of a product, which in this case is tequila. Therefore, this chapter addresses the possible contributions of sensory evaluation and consumer science to the tequila industry. Different studies that have been carried out on tequila are shown, ranging from sensory characterization to non-sensory attributes that influence the choice of a tequila. ©The authors ©Elsevier ©Science Direct.

    Vanilla is native to Mexico and has social-cultural and economic importance. It is sensory characteristics are developed during the curing process, which is associated with the region where it is carried out since the know-how of each locality is involved. In this sense, this work aimed to evaluate the influence of the curing process. Four different processes from four regions (SJA, SLP, CQ and EPM) were considered, taking into account two curing conditions. Additionally, sample control was considered. The moisture content, protein, ether extract, ash and pH were analyzed. The aromatic profile was evaluated by the RATA methodology and liking level. Except for ash content, the process influenced the other physicochemical parameters. The moisture contents of SLP and CQ samples from Period 1, as well as SLP samples from Period 2, comply with the current Mexican Standard. SJA vanilla was “slightly” accepted in both periods, surpassing the control sample. In contrast, the CQ sample was the least preferred. Thirty-five aromatic descriptors were generated. At the sensory level, a clear separation of vanillas was observed according to the type of curing. The attributes described included caramel, dry fruit, fruity, honey, maltol, rancid, sweet, tree bark, vanilla and ashes, which boosted the liking level. On the other hand, the descriptors chemical, moisture, dairy, spicy, wood and lipids had a negative effect, proving that these factors can alter the aromatic balance, giving an unpleasant smell and reducing preference. It was confirmed that the curing process influences physicochemical parameters, the aromatic profile and the liking level. However, it would be necessary to consider other variables. ©The authors ©Foods ©MDPI.
