FOOD ANALYSIS AND QUALITY CONTROL - 2022/3

Module Overview

The module provides theoretical and practical knowledge and skills required to undertake food analysis and quality control in order to improve the nutritional, eating quality and safety of food products. The lectures, practicals and tutorials form essential components of the degree in Food Science and Nutrition BD46. Students studying Nutrition (B400) and Microbiology (C500) also benefit.

Assessment pattern

Alternative Assessment

Practical re-assessment format: Write-ups of practical data using data provided by the module leader.

Assessment Strategy

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 guided learning.
  


• 
  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.
  


• 
  Their ability to present their methods and results in a format suitable for publication.
  


• 
  Their ability to communicate information to different audiences.
  


• 
  Their ability to apply knowledge and understanding to real-world situations where information may be incomplete.
  

 

Thus, the summative assessment for this module consists of:

Coursework 1 – 1 written practical report covering the analysis of meat products, comprising an introduction, short methods section, calculations, results and discussion (answering specific questions) written individually. (Submission deadline: ~2 weeks after the practical). Report is worth 50% of the module mark.

Coursework 1 re-assessment format: Write-up from new data provided by the module leader.

Coursework 2 - a business case for a quality control (QC) lab for a food company. This must include the product being tested, two methods from the lecture content for this module, costings for 1 year of operation (within budget) and rationale for methods/equipment chosen. Communication style to be professional without being too technical. Case study is worth 50% of the module mark.

Coursework 2 re-assessment format: Case study for alternative products with a different budget.

Assessment briefs and rubrics are provided for both assessments.

Formative assessment and feedback

Feedback is provided individually (comments, rubric and in turnitin) on the coursework submissions within three semester weeks after submission. General feedback is provided in seminars, recorded and uploaded to SurreyLearn.

Formative feedback is provided during practicals, seminars/tutorials and via discussion boards on SurreyLearn.





 

Module aims

• To examine in detail the principles of the standard biochemical and the most modern spectroscopic and chromatographic 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
• To consolidate learning in a case study applicable to the food industry

Learning outcomes

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 and chromatographic techniques used for food analysis through lectures, captured content, seminars/tutorials, practicals and guided learning.
  


• 
  To critically discuss the advantages and disadvantages of techniques applied to the analysis of food components and the results obtained in a practical report (summative assessment).
  


• 
  To assess the results obtained in terms of the regulations related to selected food products through directed reading (summative assessments).
  


• 
  To enable the students to apply statistical methods for evaluating results in the practicals (formative assessment).
  


• 
  To consolidate and apply learning to a "real-world" situation applicable to the food industry (summative assessment).
  

 

The learning and teaching methods include:

• 
  Lectures delivered as captured content (~12h)
  


• 
  Seminars for discussing lecture content, and provide guidance/feedback on assessments (~11h)
  


• 
  Guided learning delivered as a comprehensive reading list, relevant TV episodes (~4h) and recordings of lectures and seminars (~23h) for consolidation purposes
  


• 
  Practicals (~18h) and associated captured content on techniques (~8h)
  

 

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
