  • Learning Outcomes
    Course Learning Outcomes

    1.  identify solutions to problems related to the chemical composition and functionality of food and to apply and expand upon the theoretical concepts presented in lectures.
    2.   demonstrate familiarity and competence with the practical skills and techniques used in food processing, research and analysis. This will include experimental planning, the preparation of reagents and use of basic instrumentation (spectrophotometers, viscometers, colour meters, chromatographic apparatus etc), the collection of experimental data and its presentation, analysis and interpretation.
    3.   use terminology, appropriate to the field of food chemistry, correctly and contextually.
    4.   explain the benefits and limitations (scientific and ethical) of food additives and processing aids currently used by the food processing industry and those additives which may be permitted to be used in the future.
    5.   formulate foods that are designed to address and contribute to reducing community health concerns.

    Workload

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

    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.

    Topics to be covered include:

    Food chemicals that will be investigated include esters, carbohydrates, proteins, lipids, colloids, the additives used in baking and the role of water in food chemistry. Browning reactions, rancidity and enzyme catalysed reactions will also be investigated. These areas will be explored using spectrophotometry, chromatography and a range of other instruments.
    Specific Course Requirements
    Attendance at practicals is compulsory. White laboratory coats and closed-in shoes must be worn at all times during practical sessions.

  • Assessment

    The University's policy on Assessment for Coursework Programs is based on the following four principles:

    1. Assessment must encourage and reinforce learning.
    2. Assessment must enable robust and fair judgements about student performance.
    3. Assessment practices must be fair and equitable to students and give them the opportunity to demonstrate what they have learned.
    4. Assessment must maintain academic standards.

  • 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.
