Prerequisites / Co-requisites
Pre-requisites: BMS1027 Food Science and Nutrition
The module provides theoretical and practical knowledge and skills required to undertake food analysis and quality control in order to improve the nutritional and eating quality and safety of food products. The lectures, practicals and tutorials form essential components of the degrees in Nutrition and Food Science BD46, Food Science and Microbiology CD56.
To examine in detail the principles of the standard biochemical and the most modern spectroscopic, chromatographic and rheological techniques used for food analysis
To examine critically the advantages and disadvantages of techniques applied to the analysis of food components and the results obtained
To assess the results obtained in terms of the regulations related to selected food products
Statistical evaluation of results

Analytical quality control and sample preparation
UV-visible spectrophotometry, principles and applications
IR, NIR, FTIR spectroscopy
NMR and Raman spectroscopy; spectrofluorimetry principles and applications
Electrophoresis, non-dissociating and dissociating PAGE, iso-electric focusing; applications
Rheology and food texture
Organolepsis: sensory analysis
Sensory analysis of foods
Protein analysis - proximate analysis of meat products
Sugars – determination of sugars in different jams
Physical and chemical properties of starches
Physical and chemical properties of fats and oils
Analysis of caffeine by HPLC - statistical evaluation and precision
Methods of Teaching / Learning
The learning and teaching strategy is designed to:
• To equip the student with a detailed knowledge of the principles of the standard and advanced biochemical, spectroscopic, chromatographic and rheological techniques used for food analysis through lectures and practicals and directed reading.
• To critically discuss the advantages and disadvantages of techniques applied to the analysis of food components and the results obtained in practical reports.
• To assess the results obtained in terms of the regulations related to selected food products through directed reading
• To enable the students to apply statisctical methods for evaluating results in the practicals
The learning and teaching methods include:
• Lectures (approx. 2 h per week total 15 h)
• Practicals 7 x 3 h Total 21 hours
• Tutorials ( pre- and post-practical tutorials)
• Class discussions
The assessment strategy is designed to provide students with the opportunity to demonstrate:
The knowledge gained on the principles of analytical techniques obtained from lectures and practicals
The knowledge gained on the advantages and disadvantages of analytical techniques taught through lectures, practicals and from directed reading.
Their practical skills in the laboratory.
Their ability to analyse and critically discuss the results obtained in the practicals.
Their ability to discuss the results obtained in relation to the lectures, published literature and food legislation
Thus, the summative assessment for this module consists of:
Course work – 3 reports covering practicals on the analysis of meat products, sugars and caffeine.
Each report comprises an introduction (200 words), a short methods section, relevant results (length as required) and discussion (approx. 600 words) written individually. (Submission deadline: 2 weeks after the practical). Each report is worth 20 % of the module mark.
Practical re-assessment format: Write-ups from practical data.
The examination length is 2 hours. Candidates answer 4 out of 7 questions. The examination is worth 40 % of the module mark.
Formative assessment and feedback
Feedback is provided individually on all the practical reports within three weeks after submission.
The formative assessment comprises feedback during classes and tutorials and for practicals not assessed (e.g. sensory, gelation/foaming of proteins, analysis of different starches and the analysis of fats and oils).
The practicals are usually done in groups of four and the results are obtained by the whole group and discussed during the practical sessions (or soon after). In the assessed practicals all the data from all the groups are discussed so that the group results can be compared.
Verbal feedback in class discussions and tutorials.
