Course Learning Outcomes
1 Demonstrated ability to identify solutions to problems related to the sensory analysis of food and to apply and expand upon the theoretical concepts presented in lectures. 2 Demonstrated familiarity and competence with the practical skills and techniques used to analyse the sensory properties of food. This will include experimental planning, the preparation of suitable samples and the use of instruments e.g. viscometers and colour meters, as well as the collection of experimental data and its presentation, statistical analysis and interpretation. 3 Ability to use terminology, appropriate to the field of sensory analysis, correctly and contextually. 4 Ability to explain the benefits and limitations (scientific and ethical)
of the sensory evaluation of food and be able to recommend, justify and
critique commonly used methods of sensory analysis.
5 Capacity to formulate foods that meet specified sensory requirements and
which are intended to contribute to reducing community health concerns.

Learning & Teaching Activities
Learning & Teaching ModesLectures are used to deliver content relevant to the specified Knowledge Objectives and practical activities are used to enable students to achieve the specified Skill Objectives. Lectures also include open discussion, sample problems and demonstrations. Time allocated to lectures and practicals can be used for tutorials on request.
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).

Summary of key components of the courseDiscussion of questions from past exams
The University's policy on Assessment for Coursework Programs is based on the following four principles:
- Assessment must encourage and reinforce learning.
- Assessment must enable robust and fair judgements about student performance.
- Assessment practices must be fair and equitable to students and give them the opportunity to demonstrate what they have learned.
- Assessment must maintain academic standards.
Assessment Task Task Type Due Weighting Learning Outcome Written assignment #1 Summative Monday Week 4 15% LO 1-5 Written assignment #2 Summative Monday Week 7 15% LO 1-5 Written assignment #3 Summative Monday Week 11 20% LO 1-5 Final Exam Summative To be announced 50% LO 1-5
The written assignments include the following tasks:
- Tasks that require recall of knowledge given in lectures, practicals and readings
- Tasks that require comprehension of unfamiliar relevant scientific text and scenarios
- Tasks that require the application of knowledge, laws, principles and guidelines to unfamiliar problems
- Tasks that require the analysis of data which is either fictitious, sourced from the literature or generated during laboratory sessions
- Tasks that require information to be synthesised and which conforms to a project brief, e.g. instructions for making a new food product
- Evaluation and critical appraisal of novel information
Exemplars of answers to assignment questions will be provided.
The final exam also challenges students with tasks of the type listed above. Exemplars can be viewed in past exam papers.
Marking schemes for all assessment tasks are supplied. Grading of student submissions is undertaken by the lecturer.
SubmissionHard copies of assignments must be submitted to the Administration office in Corridor 2 of K Block by the date and time that will be specified. Submission dates will always be dates on which lectures are delivered to avoid the need to travel to the TAFE campus on other days. A cover sheet is required and will be provided via MyUni. Assignments will not be accepted more than 1 week after the due date. Students are urged to contact the lecturer by email if they are unable to submit an assignment by the due date. Assignments will not be accepted after 1 week beyond the due date. Assignments are usually marked and returned with model answers 2 weeks after the due date.
Late submission of assessments
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.
Grades for your performance in this course will be awarded in accordance with the following scheme:
M10 (Coursework Mark Scheme) Grade Mark Description FNS Fail No Submission F 1-49 Fail P 50-64 Pass C 65-74 Credit D 75-84 Distinction HD 85-100 High Distinction CN Continuing NFE No Formal Examination RP Result Pending
Further details of the grades/results can be obtained from Examinations.
Grade Descriptors are available which provide a general guide to the standard of work that is expected at each grade level. More information at Assessment for Coursework Programs.
Final results for this course will be made available through Access Adelaide.
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.

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.
