FOOD09015 2022 Food Chemistry and Analysis
The structure and physicochemical properties associated with various nutrients can play important roles during the formulation and stability of food matrices. Furthermore, the degradation of nutrients through natural and industrial processes can often lead to negative implications in relation to the pro-longed quality and safety a food product. Through this module, students will gain the necessary knowledge, understanding and insights to be able to discuss the relationship between nutrient structure and function within a food product. In addition, this module will address the stability of nutrients when subjected to pro-longed storage, industrial processing techniques and the incorporation of additives, thus providing students with the ability to discuss and troubleshoot the perceived barriers and solutions associated with product shelf-life.
Learning Outcomes
On completion of this module the learner will/should be able to;
Recognise and differentiate between the structural features and physicochemical properties associated with various nutrients.
Understand the role played by various biochemical processes in the degradation of nutrients and the subsequent impact on food safety, quality and shelf life.
Compare and contrast the effect of industry relevant processing techniques on the stability of nutritional components within various food products.
Evaluate the importance of food additives for the protection of nutrients and subsequent shelf life extension of various food products.
Evaluate the application(s) and limitation(s) of analytical methodologies for the identification and quantitation of nutritional components within various foods products.
Teaching and Learning Strategies
The students will be exposed to a blend of learning activities e.g. in class and online lectures, independent learning and directed learning. This approach is expected to address various student learning needs. Moodle will be used to upload educational material (e.g. powerpoint presentations, recordings of online lectures and supplementary reading material) and a means of assessment (e.g. uploading assignments and presentations).
Case studies and problem based learning will be employed to facilitate deeper learning and provide the students with the skills to apply their knowledge to real life scenarios.
Module Assessment Strategies
The CA component (60%) will be assessed through a variety of assessment strategies including:
- Multi-Choice Questions (MCQs)
- Short Answer Questions (SAQs)
- Essay Based Assignment
Students may be assessed individually or in group environments with a strong emphasis on continual improvement and skills building.
The Final exam (40%) will be a closed book written exam at the end of the semester.
Repeat Assessments
In situations where the Learner does not achieve a passing mark (40%) for this module, the Examiner will review their assessments and identify the learning outcomes affected. The Examiner will then issue the Learner with repeat assessment(s) to compensate. In cases where repeat assessment(s) is required to achieve a passing grade, the overall module grade will be capped (40%).
Indicative Syllabus
LO 1) Recognise and differentiate between the structural features and physicochemical properties associated with various nutrients.
Students will learn to distinguish between the monomeric building blocks that make up macro nutrients (i.e. fats, proteins and carbohydrates). Furthermore, students will be expected to discuss how these structural differences, and their associated functional properties, could influence the formulation and stability of relevant food matrices.
LO 2) Understand the role played by various biochemical processes in the degradation of nutrients and the subsequent impact on food safety, quality and shelf life.
Students will learn about the impact certain biochemical process (e.g. lipid oxidation and enzymatic browning) can have on the safety, nutritional quality, and subsequent shelf-life of food products. Students will be expected to understand the reactions involved in these processes and further assess their impact when applied to relevant case studies.
LO 3) Compare and contrast the effect of industry relevant processing techniques on the stability of nutritional components within various food products.
Students will learn about the impact certain processing techniques (e.g. thermal and non-thermal) can have on the nutritional quality of food products. In addition, students will be expected to critically appraise the advantages and limitations of such processes when applied to relevant case studies.
LO 4) Evaluate the importance of food additives for the protection of nutrients and subsequent shelf life extension of various food products.
Students will be expected to understand and discuss the role of different additives in maintaining the quality and safety of food products. In addition, students will be expected to expected to critically appraise the advantages and limitations their use when applied to relevant case studies.
LO 5) Evaluate the application(s) and limitation(s) of analytical methodologies for the identification and quantitation of nutritional components within various foods products.
Students will learn about the theory and application of various analytical techniques used in the determination of the nutritional composition of foods. Students will be expected to rationalise the selection of the most appropriate techniques in specific cases, while also being able to discuss their limitations.

ISBN 9783662072790 ISBN-13 3662072793
The 3rd edition has been extensively re-written and many topics of particular interest to food technologists have been added or completely revised. The book now comprises more than 620 tables and 472 figures, including the structural formulae of around 1,100 food components. This standard text and reference is logically organized according to food constituents and commodities. It provides students and researchers in food science, food technology, agricultural chemistry and nutrition with the up-to-date information they require. The extensive tables for easy reference, the wealth of information, and the comprehensive subject index aid advanced students to acquire in-depth insight into food chemistry and technology and make this book also a valuable on-the-job reference for chemists, food chemists, food technologists, and more. Praise for the first edition: "Few books on food chemistry treat the subject as exhaustively researchers will find it to be a useful source of information.
