Understanding and applying the principles of descriptive analysis. Advanced methods of data collection and analysis for consumer data. Applications of sensory science in the food industry and research settings.
In this paper, students will gain in-depth knowledge in a range of advanced sensory
evaluation methods. They will be asked to undertake a substantial group-based project
using qualitative descriptive sensory analysis. Upon completion of this paper, students
are expected to have theoretical and practical knowledge of how to recruit, train
and monitor performance of a descriptive sensory analysis panel. They will learn how
to derive/generate/select descriptors to develop a sensory vocabulary for descriptive
analysis techniques. The key methodological features of descriptive techniques, as
well as their major advantages and disadvantages, will be discussed. Case studies
of different descriptive techniques will be discussed in class to enhance understanding.
Students will also gain an understanding of the most commonly applied consumer hedonic test methods and important considerations to take into account when performing consumer tests. This paper will also present the alternative consumer measures presently used in consumer sensory testing, with discussions around their advantages and limitations.
Issues of statistical data analysis will also be dealt with throughout the paper. Students will become knowledgeable in using analysis of variance to analyse both descriptive sensory analysis and consumer hedonic data. Students will become skilled in interpreting sensory data and understanding practical relevance of statistical results. Statistical analysis of sensory test data will involve SPSS or R.

- Learning Outcomes
- On completion of FOSC 306 students are expected to be able to:
- Compare and contrast different descriptive sensory analysis methods and consumer sensory test methods and outline their advantages, disadvantages and limitations
- Apply such methods as a result of understanding the information each test provides, how to organise and carry out the chosen test, how to apply appropriate statistical analysis methods and, finally, how to interpret the results obtained
- Design and carry out both descriptive sensory analysis and consumer sensory testing on selected commercial food or beverage products
- Describe methods to screen prospective panellists and have some experience of planning and undertaking appropriate training of a panel for a selected descriptive sensory test
- Apply appropriate statistical methods for the analysis and interpretation of data obtained from descriptive sensory analysis and consumer sensory tests and use graphic presentations to communicate and interpret results
- Explain appropriate uses of multivariate analysis in sensory and consumer testing (PCA, GPA, preference mapping)
- Interpret and critically assess published sensory science research
- Discuss current and future directions of sensory science
