FOOD SC 3540WT - Food Chemistry III

Waite Campus - Semester 1 - 2023

This course covers important concepts of the chemical, physical and functional properties of food constituents and the chemical changes these constituents undergo during handling, processing and storage including those that limit food shelf life. Food chemistry is of central importance to food science, it is interdisciplinary in nature due to the intersection of engineering, biological, and physical sciences which are used to study the nature of foods, the causes of deterioration, the principles underlying food processing, and the improvement of foods from a consumer and sustainability perspective. The aim of the course is to provide the students with a deep understanding of how food components contribute to overall quality of foods; and to enable students to evaluate and explain how the highly complex nature of food may result in a multitude of desired and undesired reactions which are controlled by a variety of parameters. Students learn about the chemistry and analysis of food and its components. How to interpret the food legislation prescribed by the Food Standards Code, and gain practical experience in analysing food components.

  • Learning & Teaching Activities
    Learning & Teaching Modes
    Lectures are used to deliver content relevant to the knowledge-related outcomes and practical activities are used to enable students to achieve the skill-related outcomes. Lectures also include open discussion, sample problems and demonstrations. Time allocated to lectures and practicals can be used for tutorials on request.
    Workload

    The information below is provided as a guide to assist students in engaging appropriately with the course requirements.

    A student enrolled in a 3 unit course, such as this, should expect to spend, on average 12 hours per week on the studies
    required. This includes both the formal contact time required to the course (e.g., lectures and practicals), as well as non-contact time (e.g., reading and revision).
    Learning Activities Summary
    Learning activities are centred around the properties of the major classes of chemicals that make up food, specific reactions common in foods, physical properties of foods and the detection of chemicals and measurement of food properties.

    Assessment Detail
    Major Food Component Assignment (20%) Due Week 8
    Comprises of short answer questions. This assignment will probe student understanding of the chemical and physical properties of major food components, specific chemical reactions common in foods and methods of detecting and measuring these food components. Students receive feedback within 4 weeks of the written assignment deadline.

    Laboratory Calculations (20%) Due Week 12
    Comprises of a series of questions requiring students to demonstrate ability to complete calculations common in food chemistry and to be able to explain the relevance of the results in the context of food. Students receive mark and feedback within two weeks of the due date.

    Online Quizzes x 4 (5% each, total of 20%) Due Week 3,6,9,13
    Students will complete a total of 4 online quizzes during semester (worth 5% each). Quizzes will consist of multiple choice and short answer questions and relate to previous practicals and the relevant theory covered in the lectures. Students receive feedback and mark within two weeks of the quiz closing.

    Final Examination (40%, held during the official exam period)
    This final 2-hour exam examines all components of the course and will consist of multiple choice and short answer questions. Short answer questions are the same format as those in the written assignments.
    Submission
    If an extension is not applied for, or not granted then a penalty for late submission will apply. A penalty of 10% of the value of the assignment for each calendar day that the assignment is late (i.e. weekends count as 2 days), up to a maximum of 50% of the available marks will be applied. This means that an assignment that is 5 days late or more without an approved extension can only receive a maximum of 50% of the marks available for that assignment.

  • Student Feedback

    The University places a high priority on approaches to learning and teaching that enhance the student experience. Feedback is sought from students in a variety of ways including on-going engagement with staff, the use of online discussion boards and the use of Student Experience of Learning and Teaching (SELT) surveys as well as GOS surveys and Program reviews.

    SELTs are an important source of information to inform individual teaching practice, decisions about teaching duties, and course and program curriculum design. They enable the University to assess how effectively its learning environments and teaching practices facilitate student engagement and learning outcomes. Under the current SELT Policy (http://www.adelaide.edu.au/policies/101/) course SELTs are mandated and must be conducted at the conclusion of each term/semester/trimester for every course offering. Feedback on issues raised through course SELT surveys is made available to enrolled students through various resources (e.g. MyUni). In addition aggregated course SELT data is available.

  • Student Support
  • Policies & Guidelines
  • Fraud Awareness

    Students are reminded that in order to maintain the academic integrity of all programs and courses, the university has a zero-tolerance approach to students offering money or significant value goods or services to any staff member who is involved in their teaching or assessment. Students offering lecturers or tutors or professional staff anything more than a small token of appreciation is totally unacceptable, in any circumstances. Staff members are obliged to report all such incidents to their supervisor/manager, who will refer them for action under the university's student’s disciplinary procedures.

The University of Adelaide is committed to regular reviews of the courses and programs it offers to students. The University of Adelaide therefore reserves the right to discontinue or vary programs and courses without notice. Please read the important information contained in the disclaimer.
