This course aims to develop first-hand insights in, and advanced practical skills on, the entire process of food product development/optimisation, drawing relationships between instrumental data of physical and chemical properties of food, sensory perceptual data, and data on consumer preferences. The student will understand the associations between process and product variables on the one hand, and sensory perception and consumer preference on the other hand in an integrated way. Importantly, they will have to interpret and critically assess the relationships between these data and be able to draw informed conclusions/recommendations on the best product formulation.
The course will help develop team learning and management skills as well as individually-oriented research abilities during the whole course. The students, organized in groups of 4-6 people combining different backgrounds will work on a food case study which involve consumer-oriented sensory science problems as experienced by sensory specialists working in a company within the food industry. In groups, the students will have to make informed decisions on which instrumentation and advanced food-consumer-oriented sensory experiments to conduct to be able to successfully address the company's problem/goal. Advanced tools for instrumental measurements are combined with methods for sensory data analysis. Instrumental measures, carried out within the context of intensive practicals depend on the specific problem, but may include colour/video measurements, image analysis, texture and viscosity measurements, olfactometry, HPLC, and antioxidant activity. The students will also decide the most appropriate sensory and consumer techniques based on timing and resources limitations (as it happens in real-life industry cases). Profiling methods could be consumer-based methods such as free-choice profile, flash profile, CATA, etc. In addition, preference data will also be collected from consumers. Students will link these three sets of results with the help of the multivariate statistical analyses.

Learning outcomes:

After successful completion of this course students are expected to be able to:
- assess the most common challenges that food companies face during product development;
- design an experimental protocol in order to address a given problem/goal;
- recognize instrumental analysis methods to apply to address a specific research problem;
- apply the most convenient instrumental analysis methods;
- evaluate which sensory and consumer tests are available and make an informed decision on the most convenient one(s);
- analyse independently the results of different instrumental, sensory, and hedonic data;
- critically reflect on the results and use synthesis skills to deduce the most relevant information;
- communicate effectively scientific results and managerial advice on the most favourable solutions providing a robust rationale for the procedure followed.


Lectures will be given during week 1 in the mornings. Several topics related to real-life case studies will be addressed reflecting the challenges that a company faces regularly. The lectures will count with the input of guests from different industries, who will share their experiences from a practical and managerial perspective. In addition, some lectures with key points on practical issues about instrumental and sensory and consumer techniques will be given as reminder for students, but from a problem-solving view. These lectures are intended to encourage conversation between the students and the lecturers and invited industry members. During the course additional hand-outs may be provided to complement the presentations.

Practicals The course consists of three weeks of practical intensive and extensive training. The practicals are carried out in the late mornings and afternoons of week 1 and week 2. Intensive practical training :Students work in groups of 4-6 people on the optimisation of one product that they will develop in the laboratory. They will formulate the product having some constrains and restricted options. On these samples they will perform several physical and chemical tests, combined with sensory and consumer data collection following the correct protocols.
Extensive practical training: This block will also involve some consumer techniques which the groups are expected to conduct under minimal supervision. All the datasets will be formatted appropriately for the statistical tests to be used (significant differences between samples, relationship between physicochemical and sensory attributes, and drivers of liking, or e.g., healthiness perception). Datasets will be interpreted and only the most valuable output (tables and figures) will be selected and included in an individual report.


- an individual report of the practical work and the analyses of the data (75 %; individual mark);
- the group presentation and performance during the course (25%);
Attending all practical's is required. For the report at least an 5.5 is required to pass this course.
