Going beyond sensory and hedonic aspects: A Brazilian study of emotions evoked by beef in different contexts.

For deeper insight into beef consumer experiences during consumption, sensory descriptions seem to be insufficient, and exploration of emotions evoked by this product are required. In this context, the present study aimed to evaluate the emotions evoked by beef consumption in different contexts. To that end, this work was structured as follows: 1) Emotional vocabulary development; 2) Selection of beef cuts; and 3) Emotional profiling of beef cuts. The emotional vocabulary was useful for characterizing emotions evoked by two beef cuts with different sensory profiles, in different contexts, considering a within-subjects design. Rump cap samples showed the highest liking and were associated with positive emotions, while outside flat samples were less liked and characterized by negative emotions. The evoked context had no effect on hedonic and emotional intensities, but increased the number of emotions elicited by consumers. The correlation of sensory, hedonic and emotional information indicated that tenderness and internal color of beef were correlated with positive emotions and higher liking scores.

Original burger (traditional) or burger with mushroom addition? A social representation approach to novel foods.

Currently, consumers' interest in healthy products has attracted the attention of academia and the meat industry, which has focused mainly on incorporating ingredients with healthier properties. In this context, the aim of this study was to investigate the social representation of original burgers and burgers with mushroom addition considering different sexes and body mass indexes (BMIs) of individuals. Thus, 209 Brazilians answered a word association task followed by a word classification based on their importance and valence for original burgers and burgers with the addition of mushrooms. To obtain the structure of social representation, the words were positioned into four distinct zones based on their frequency of elicitation and importance. Also, the polarity index was used to give a connotation to the words. Three groups of consumers were identified. The first group (consumers with class-1 obesity of both sexes) associated the original burger with positive categories (cheese, juicy, seasoned, food, tasty, joy, salad and delicious). The second one (female consumers with pre-obesity and class-1 obesity) associated the burger with the addition of mushrooms with the elements price, different, vegetarian, flavor, gourmet and healthy. Finally, the third group (men and women for both stimuli and with a wide range of BMI) characterized burgers with sensory attributes, feelings and moments of consumption. In conclusion, the social representation of the original burger and the burger with the addition of mushrooms differed among consumers, suggesting that the main associations can be the main motivations for the consumption of a certain product.

Measuring dynamics of emotions evoked by the packaging colour of hamburgers using Temporal Dominance of Emotions (TDE).

The packaging colour is one of the main extrinsic factors related to sensory perception as it can alter the emotions evoked by the product and, therefore, influence the moment of purchasing a product. There are several methods used to analyse emotions, but the Temporal Dominance of Emotions (TDE) approach stands out. This method allows the study of the temporality of dominant emotions until eating a portion of the hamburger. The aim of this work was to use TDE and overall acceptance to study the dynamic of the emotions evoked by the packaging colour of hamburgers, from first sight of the packaging until eating of a portion of hamburger. The twelve attributes of emotion, determined previously via a focus group, were presented to the consumers to evaluate three different stimuli formed by three different coloured packaging (green, white and red) and the same hamburger. The results showed that acceptance alone is not sufficient to understand the choice of a product, most likely because it does not capture the emotions involved in the consumption of a hamburger. Significant differences were found in the dynamic perception of emotions influenced by the packaging colour along time, mainly during the first "packaging - consumer" contact. Finally, the study of the dynamics of emotions provided valuable and complementary information to overall acceptance.

Understanding consumers' dynamic sensory perception for bacon smoked with different Brazilian woods.

The aim of the present study was to obtain the dynamic sensory profile of smoked bacon using Temporal Dominance of Sensations (TDS). Eight samples were studied considering different smoking process: six samples were submitted to conventional smoking using different woods from reforestation and two samples were manufactured with liquid smoke. Seventy-eight regular bacon consumers evaluated the samples using the TDS methodology. TDS data were analyzed based on the sequence (bandplot by attribute and trajectory map) and dominance duration (univariate and multivariate techniques). TDS results showed differences between samples in terms of rate, trajectory and duration of dominant sensations. These differences can be mainly explained by the smoking processes used in their manufacture and by the oral work involved in the mastication task. Overall, TDS was a promising method for capturing temporal sensory changes in smoked bacon.
