FOOD SCIENCE AND NUTRITION - 2022/3
Module code: BMS1027
In light of the Covid-19 pandemic, and in a departure from previous academic years and previously published information, the University has had to change the delivery (and in some cases the content) of its programmes, together with certain University services and facilities for the academic year 2020/21.
These changes include the implementation of a hybrid teaching approach during 2020/21. Detailed information on all changes is available at: https://www.surrey.ac.uk/coronavirus/course-changes. This webpage sets out information relating to general University changes, and will also direct you to consider additional specific information relating to your chosen programme.
Prior to registering online, you must read this general information and all relevant additional programme specific information. By completing online registration, you acknowledge that you have read such content, and accept all such changes.
This module covers the major food components (water, fats, carbohydrates and protein) in terms of their nature and role in foods. It also covers the nutritional principles of fat carbohydrate and protein and how dietary macronutrient requirement values are derived. These aspects underpin the areas of food science and nutrition that follow later on in the programme.

Revision tutorial covering past questions and expected answers
|Assessment type||Unit of assessment||Weighting|
|Examination||EXAMINATION - SHORT ANSWER QUESTIONS - 120 MINS||100|
The assessment strategy is designed to provide students with the opportunity to demonstrate that they can describe, explain and understand the fundamental chemical and biochemical properties of food components as well as the nature and role of food macronutrients. The assessment strategy is also designed to provide students with the opportunity to show that they understand the role of macronutrients and the derivation and application of dietary macronutrient requirement values for individuals and populations.
Thus, the summative assessment for this module consists of:
· The examination is 2 hours in length and is composed of 12 short answer questions that cover the module topics. All short answer questions should be attempted. The weighting for the exam is 100 %.
Formative assessment and feedback
A compulsory formative short test (5 questions, 50 mins) is given in week 5/6 in Semester 1. This test is in the same short answer format as the main exam but only covers the material given in the first 19 lectures. The test provides students with the opportunity to answer questions under exam conditions and to receive an indication of their performance and understanding of the module content up to that point. Two one hour feedback tutorials are provided by lecturing staff after the formative test. At these tutorials students receive personalised feedback through their annotated test scripts. Lecturers also go through each question in turn during the tutorial and there is an opportunity to discuss the answers in class.
- Emphasise the nature and roles of water in foods and methods for its analysis
- Provide an appreciation of the nature and role of lipids in foods, their extraction and purification from natural sources, their modification and their deterioration
- Provide an appreciation of the nature and roles of proteins in foods
- Explain the nature and function of simple sugars, and their derivatives, in food
- Provide a sound understanding of the nutritional principles of the major food components (proteins, lipids and carbohydrates)
- Provide an understanding of the derivation and application of dietary macronutrient requirement values for individuals and populations

Methods of Teaching / Learning
The learning and teaching strategy is designed to:
Provide students in the early stages of their programme an appreciation and thorough understanding of the nature and role of the key macronutrients in foods as well as the fundamental chemical and biochemical properties of food components and ingredients. This aligns with the programme strategy to help students to acquire and develop a thorough understanding of food science and nutrition in the early stages of their programme.
The learning and teaching methods include:
• Lectures (with interactive question and answer sessions) 3-4 hour lectures per week x 11 weeks
• Formative test with 2 hours of feedback tutorials
• Revision tutorials with example test questions
• SurreyLearn video clips on some aspects of the module
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.
