## 3 Results and Discussion
### Results of the Sensory Analysis of the Developed Formulations
#### 3.6.1 Liking and Buying Intention of the Developed Beverages per School
Regarding the buying intention, the participants did not show a clear intention to purchase or not the developed beverages, except for the BC formulation (the participants commented that \"Probably would not buy it\"). Apparently, its low impact of smell and flavor affected negatively the buying intention for this formulation. Significant differences for buying intention variable were found only for ICSA school (Figure 2D). The participants in the sensory tests belong to the age range between 19-25 years old, so their beverage consumption habits could have influenced their responses since several studies [69] state that the most consumed beverages by Mexicans between 19 and 29 years old are sodas (carbonated and non-carbonated), beverages based on fruit juices (with and without added sugar), _aguas fresca_, and natural fruit juices (prepared with 100% fruit without added sugar). Nutritional labels and health warnings in sweetened beverages can help to discourage their consumption [70]. 6.2 Liking and Buying Intention of the Developed Beverages Per Population with Normal Weight (N) and with Overweight and Obesity (OO)  
Results of the degree of liking and buying intention for the developed beverages according to the weight condition are presented in Figure 3. The Student's \(t\)-test showed significant differences between the color (t = 2.33; \(p\) = 0.020) and flavor (t = 2.14; \(p\) = 0.032) only for BB formulation (Figure 2A,B, respectively). Participants with overweight or obesity (OO) expressed a higher degree of liking for BB flavor, while participants with normal weight (N), liked most the color of this formulation. The evaluation of liking data reflected that both populations (N and OO) showed the same responses for the smell of the four developed beverages and, except for BB formulation, also for the flavor and color. Regarding this last attribute, [PERSON] et al. [71] observed that the color has a significant effect on some attributes related to aroma and flavor intensity for grapefruit-like beverages. In their research, the red color liked more than the yellow and a low over high aroma. Similarly, in our research, pink or reddish beverages were preferred over the yellow-brownish ones. These results indicate that the bougainvillea could be an excellent source of natural color for the development of beverages of this type. This flower, besides the color, provides compounds with antioxidant capacity that will confer bioactive properties to the final product [61]. Regarding the buying intention, it was observed that there were no significant differences nor by institute nor by populations with normal weight and with overweight or obesity (means between 4.1 and 4.5). In general, no clear intention neither to buy or not the developed beverages was observed. The lack of sugar in the formulations may explain the low buying intention values observed. Our results are in agreement with [PERSON] et al. [72]. These authors suggested the lack of sugar as the cause for the low acceptance means observed for unsweetened Brazilian wild Passiflora infusions, mentioning that people who consume unsweetened beverages like tea are a small and specific group of consumers. The beverages developed in our research were intended as healthy alternatives to soft drinks, hence the addition of sweeteners has not been considered. [PERSON] et al. [73] stated that providing information about the health properties of products can be an effective mechanism to increase the liking and the purchase intention. In this regard, [PERSON] et al. [74] observed a positive effect of providing health information about acai (_Euterpe olerca_) juices on hedonic measures as well as on purchase intention. Mexico is among the top ten countries in the world including Chile, United States, Argentina, Saudi Arabia, Germany, the Netherlands, Slovakia, Austria, and Brazil with the highest intakes of sugary drinks [75], exceeding the WHO recommended calorie intake.
