Sensory Evaluation of Food
Sensory science is a discipline that uses humans and their senses to measure and evaluate products or other sensory stimuli in an objective or personal manner. The course introduces the field of sensory science as it relates to food and nutritional sciences. Different aspects on how to evoke, measure and evaluate sensory properties of foods are presented within a framework of different methodological approaches.
Special focus will be on basic sensory evaluation methods (discrimination, descriptive, temporal, etc.), factors influencing sensory judgments, common laboratory practices (planning, sample order presentations, response scales, etc.) and panels (recruitment, selection and training) as well as data analysis. Relationships between sensory measures (visual, flavour and texture) and instrumental analyses (physical and chemical) will be presented in relation to validity and predictive capability in food quality control as well as shelf life testing. The wider implications of changing sensory properties of foods for consumer preferences and behaviour are briefly introduced.
The student will be trained in making appropriate choices of sensory methods and data analysis for different situations, e.g. within food production, quality control and product development.
