This module covers the major food groups, developing an understanding of the chemistry, biochemistry and physical properties of foods and food components in relation to the production, processing, preparation and consumption of foods, and the way food commodities may be manufactured, placing the food industry and food labelling in a nutritional context. The module also focusses on how commodity groups are processed into foods and the effects on nutrients of processing and preservation. Food sustainability and current trends will be highlighted. In addition, the module contains a series of laboratory practicals that include the proximate analysis of foods (e.g. moisture, fat, protein, ash) and measurement of food energy. The second section looks at the microbial world and how microorganisms could cause food spoilage, foodborne diseases as well as contribute towards preservation of our food. The major microorganisms will be discussed, focusing on intrinsic and extrinsic factors affecting their growth in food. Also how microorganisms are controlled through food preservation and food processing methods will be discussed in detail.
The aims of this module are aligned with the qualification descriptors within the Quality Assurance Agency’s Framework for Higher Education Qualifications. This module aims to give students insight into the biochemistry of foods as key commodities and their manufacture and analysis of nutrient content and labelling. In addition how and why foods are processed, the effects of processing on nutrients and the principles of food spoilage and preservation, hygiene and safety will be covered. The module also seeks to develop competence in discussion and written work, encouraging clarity and scientific rigour; tools often used in many employment settings, which will facilitate progression to higher level modules.
Prior learning requirements
NU4005 (Human Nutrition)
The specified learning outcomes will be developed around a framework based on the following subject matter:
General properties of food components LO 1
Chemical and physical characteristics of foods LO 1
Principles of food analysis – chemical, physical LO 1, 2
Nutrition and food processing LO 2
Food labelling LO 3
Analyse the issues relating to the provision of food in the EU and elsewhere with respect to market forces, food safety, sustainability and government policies LO 3, 6
Principles of quality assurance in the food industry and food chemical safety LO 3, 6
Microbial world, Factors affecting the growth of microorganisms LO 4, 6
Food infection and intoxications, Traditional food preservation and processing methods, Emerging technologies in food preservation, Major groups of microorganisms causing food-borne diseases. LO 4, 6
Diet & gut flora LO 5
Principles of food safety & hygiene LO 6
Balance of independent study and scheduled teaching activity
The syllabus will be developed through lectures (58h), tutorials/case studies (20h) and laboratory work (22h). A significant amount of learning material will be made available through the University Weblearn. Students are to carry out proximate analysis and extended analysis of foods, prepare a food label that conforms to current legal requirements and write a report about this and the factors that affect the reliability of analytical data. Students will spend time preparing for and undertaking on-line assessments (30 hours) Students will be required to undertake further study in-depth on their own to develop their knowledge (100h).
Employability: students will develop their ability to collate and manipulate data using spreadsheets (Excel). Students will develop their ability to analyse strategies to manage food spoilage and food-borne diseases at home, care homes and hospitals and to establish a healthy diet.
On successful completion of this module students will be able to:
LO1. Demonstrate an understanding of the principles of the chemistry and physics of foods.
LO2. Demonstrate an understanding of food processing and the effects on nutrient content.
LO3. Interpret food labels with respect to nutrition, ingredients and legal requirements.
LO4. Demonstrate an understanding of the causes of food spoilage, food-borne disease and strategies for prevention.
LO5. Demonstrate an understanding of human microbiota and how diet plays a role in their balance.
LO6. Apply food safety legislation knowledge to the practice of nutritionists and evaluate the safety of food services.
This module will be assessed by two web-based Progress tests (30 min each) covering syllabus topics food chemistry, processing, quality assurance and food safety (chemical), and submission of a Nutritional Analysis of Food Label report (2000 words) plus appropriate figures, tables and references. Other assessment components include online assessments (3 x 20 minutes progress tests), covering syllabus topics including food spoilage, food infection and intoxication, food preservation methods as well as diet and gut flora and the two practical sessions, as well as a coursework essay (2000 words) on topics related to food safety and health. To pass the module, students must get an overall mark of 40% or above.
The two web-based tests, each designed for 30 minutes, will be given in weeks 6 and 11. Each on-line test has a weighting of 10% towards the module. Students have one attempt to take each test. The on-line tests will allow students to test their progress and allow the module leader to comment on their efforts, as well as providing an element of summative assessment. The web-based tests provide formative feedback for the students’ final report and further assessments. The final coursework essay should be submitted online via Weblearn, where the students have the opportunity to check the similarity of their draft against other published material, which in turn will help the students to avoid plagiarism. Summative feedback will be provided to the students using the tools available on Weblearn. The three on-line tests, each designed for 20 minutes, will be given in teaching weeks 19, 23 and 25 to engage
learners with the taught material and provide both formative and summative
assessment, with opportunity for formative feedback. The average of 3 on-line tests has a weighting of 25% towards the module. Students have one attempt to take each test.
The use of the tools on Weblearn will also be considered as a way of engaging students in classroom learning and for providing regular information about current developments in the subject.
Learners are required to attend the laboratory practical sessions.
