Enhancing salty taste through odour–taste–taste interactions: Influence of odour intensity and salty tastants’ nature
2013
WOS:000315557500017 ; www.elsevier.com/locate/foodqual; International audience; Decreasing the sodium content in food products without changing consumer acceptability has become an important challenge for the food industry, and several strategies are currently under investigation to reach this goal. This study investigated the effectiveness of saltiness enhancement by an odour to maintain the perception of saltiness in reduced salt content solutions. In the first experiment, we tested the hypothesis that odour intensity drives the level of saltiness enhancement. The results showed that odour can increase the salty intensity by 25%, while no clear influence of odour intensity either in taste…
Strategies to enhance saltiness in food involving cross modal interactions
2013
A series of results is reported on cross modal odour-taste interactions as a mean to enhance salty taste in food. Salt-related odours can enhance salty taste in water solutions containing a low level of sodium chloride through odour-induced changes in taste perception. Odour-induced saltiness perception enhancement (OISE) depends on salt concentration (intensity). OISE was also found effective in low-salt content solid model cheese, but texture dependant. A significant saltiness perception enhancement induced by Comté cheese and sardine odours was observed for softer textures only. In ternary odour-sour-salty solutions, sourness enhances saltiness perception additively with salt-related odo…
Binding of Na+ ions to proteins: Effect on taste perception
2015
Abstract This study investigated the relationship between the ionic binding of sodium and salty perception in protein matrices. Protein type (i.e. gelatin, milk protein and soy protein), protein concentration and pH were varied to obtain matrices with distinct compositions and rheological properties. 23Na NMR spectroscopy was used to determine the ratio of sodium ions bound to proteins and the mobility of sodium ions. The results showed that protein type, concentration and pH affected the rheological properties of the protein matrices, the ionic binding of sodium ions and taste intensity. As the protein concentration increased, the mobility of sodium ions decreased and the ratio of bound so…
Reducing salt and fat while maintaining taste: An approach on a model food system
2013
Unbalanced diets with an excess consumption of fat, salt and low‐size sugars contribute to the development of pathologies such as obesity, cardiovascular diseases, and diabetes. As a consequence, worldwide healthcare authorities advocate salt, fat and sugar reduction in food. However, the multifunctional roles of these ingredients in both food composition and perception prevent a simple reduction of their content. Several strategies are currently investigated to design healthier food while maintaining its taste and consumer acceptability. Among these strategies, the one relying on crossmodal sensory compensation is tested within the framework of the EU‐TeRiFiQ research project. The main obj…
Developing social competence and other generic skills in teacher education : applying the model of integrative pedagogy
2016
The purpose of the study was to examine how social competence and other generic skills can be developed in teacher education using a pedagogical model called Integrative Pedagogy. This model is based on the idea of integrating the four basic components of expertise: Theoretical knowledge, practical knowledge, self-regulative knowledge, and sociocultural knowledge. The subjects of the study were 95 student-teachers. The data were collected with questionnaires. In addition to social skills, the student-teachers reported learning of domain-specific skills, generic academic skills, skills for acting creatively in different situations and development of independence. We conclude that the model o…
Teachers’ Implicit Meaning Systems and Their Implications for Pedagogical Thinking and Practice: A Case Study from Finland
2016
ABSTRACTThis qualitative case study examines teachers’ implicit meaning systems built around their core beliefs on the malleability of human qualities. Previous research has demonstrated the influence of students’ implicit theories on motivation and achievement and has presented successful interventions for students. However, research on teachers’ implicit theories and, in particular, their actualization in natural environments is lacking. The data for this study include observations and stimulated recall interviews with two Finnish teachers whose opposing implicit theories were first indicated in 2000 by Carol Dweck . The results depict how these teachers’ implicit meaning systems influenc…
The Moderating Role of Performance in the Link From Interactional Justice Climate to Mutual Trust Between Managers and Team Members.
2016
The main goal of this study was to examine the interaction between team members’ performance and interactional justice climate in predicting mutual trust between managers and team members. A total of 93 small centers devoted to the attention of people with intellectual disability participated in the study. In each center, the manager ( N = 93) and a group of team members ( N = 746) were surveyed. On average, team members were 36.2 years old ( SD = 9.3), whereas managers were 41.2 years old ( SD = 8.8). The interaction between interactional justice climate and performance was statistically significant. Team members’ performance strengthened the link from interactional justice climate to mut…
How team feedback and team trust influence information processing and learning in virtual teams: A moderated mediation model
2015
We study how team feedback influences information processing and learning in virtual teams.Group information is positively related to team learning in virtual teams.The indirect effect of team feedback on team learning via group information elaboration is moderated by team trust. This study examines a moderated mediation model in which team trust moderates the indirect effect of team feedback on team learning through group information elaboration in virtual teams. An experimental study in a laboratory was conducted with 54 teams randomly assigned to a team feedback condition or a control condition. Results provided empirical support to the moderated mediation model. We found that the indire…
The effects of virtuality level on task-related collaborative behaviors: The mediating role of team trust
2013
This study aims to analyze the mediating role of team trust in the relationship between virtuality level and task-related collaborative behaviors. Three types of task-related collaborative behaviors were studied, namely team coordination, team cooperation, and team information exchange. Drawing upon theory and research on virtual teams and trust, we hypothesized that team trust partially mediated the effects of virtuality level on team coordination, team cooperation, and team information exchange. A laboratory experiment was carried out with 65 four-person teams randomly assigned to three communication media with different virtuality levels (face-to-face, video conference and computer-media…
Conceptualizing Collaboration in the Context of Computer-supported Collaborative Learning
2015
âCollaborative learningâ has become a common expression in a wide range of spheres. We often say that we learn collaboratively when we perform a task together. However, the term âcollaborative learningâ has more complex implications than only doing a task together with peers. Successful collaborative learning is characterized by meaningful and intense interactions among peers and shared understanding of the concepts. In computer-supported collaborative learning (CSCL) learnersâ interactions are mediated by technological artifacts, therefore, the role of technologies becomes highly important from both cognitive and motivational perspectives. In this paper I discuss the essence of c…
