CHEMMAT 756 : Food Process Engineering

Engineering

2025 Semester One (1253) (15 POINTS)

Course Prescription

Application of engineering principles to food processing. Topics include: heating and thermal processing, cooling, freezing and thawing, evaporation, dehydration, the use of membranes and packaging. Innovative food processes: high pressure, pulsed electric, UV, ultrasounds and ohmic heating/cooking, and fundamental areas of engineering relevant for food processing such as heat and mass transfer. Process impact on food safety, quality and preservation.

Course Overview

Students will learn how to quantitatively analyse the basic food processing operations, such as thermal processing, chilling and freezing, drying, the use of membranes and packaging. Fundamental engineering matters, such as heat and mass transfer and fluid mechanics will be explored. Novel thermal and non-thermal processes will also be covered.  
 
At the end of the course, the student is expected to have a firm understanding of how different processing conditions and methods can affect the safety and quality of foods.

A passing mark for this course is 50% or higher, as per University policy. Students must attend the exam to pass the course; otherwise, a DNS (Did Not Sit) result will be recorded. Late submissions are not accepted for assignments, tests, or lab reports. However, late penalties will apply for Peer Assessments. 

Workload Expectations

This course is a standard 15 point course and students are expected to spend 10 hours per week involved in each 15 point course that they are enrolled in.

For this course, you can expect 36 hours of lectures, 11 hours of tutorials, 6 hours of laboratory work, 50 hours of reading and revision and 58 hours of work on assignments, reports and tests preparation. Attending the labs is compulsory in this course.

Delivery Mode

Campus Experience

Attendance is required at scheduled activities including labs to complete components of the course.

Lectures will be available as recordings.  

The course will not include live online events.

Attendance on campus is required for the tests and exam.

The activities for the course are scheduled as a standard weekly timetable delivery.

Learning Resources

Course materials are made available in a learning and collaboration tool called Canvas which also includes reading lists and lecture recordings (where available).

Please remember that the recording of any class on a personal device requires the permission of the instructor.

Health & Safety

This course will involve laboratory components undertaken in the MDLS space. Safety induction to the MDLS space will be embedded in the Canvas site of the course. Students must ensure they are familiar with their Health and Safety responsibilities, as described in the university's Health and Safety policy.

Student Feedback

At the end of every semester students will be invited to give feedback on the course and teaching through a tool called SET or Qualtrics. The lecturers and course co-ordinators will consider all feedback and respond with summaries and actions.

Your feedback helps teachers to improve the course and its delivery for future students.

Class Representatives in each class can take feedback to the department and faculty staff-student consultative committees.

Based on comments from the 2024 SET evaluation, students found several aspects of the course particularly helpful for their learning. The structured notes and example problems discussed in class were frequently mentioned as useful. Clear explanations of concepts, combined with hands-on lab sessions, greatly helped students understand the lecture material. Tutorials conducted after each part of the course reinforced learning effectively. Additionally, the guest lectures added interest and depth to the content. 
Students have identified a few key challenges and areas for improvement in the course. Based on their feedback, the following changes will be implemented:
1. The lecture notes for the drying section will be updated, and the method for calculating drying time will be revised to improve clarity.
2. Additional practice problems will be provided for the extraction section.

Academic Integrity

The University of Auckland will not tolerate cheating, or assisting others to cheat, and views cheating in coursework, tests and examinations as a serious academic offence. The work that a student submits for grading must be the student's own work, reflecting their learning. Where work from other sources is used, it must be properly acknowledged and referenced. A student's assessed work may be reviewed against electronic source material using computerised detection mechanisms. Upon reasonable request, students may be required to provide an electronic version of their work for computerised review.

Class Representatives

Class representatives are students tasked with representing student issues to departments, faculties, and the wider university. If you have a complaint about this course, please contact your class rep who will know how to raise it in the right channels. See your departmental noticeboard for contact details for your class reps.

Inclusive Learning

All students are asked to discuss any impairment related requirements privately, face to face and/or in written form with the course coordinator, lecturer or tutor.

Student Disability Services also provides support for students with a wide range of impairments, both visible and invisible, to succeed and excel at the University. For more information and contact details, please visit the Student Disability Services’ website http://disability.auckland.ac.nz

Special Circumstances

If your ability to complete assessed coursework is affected by illness or other personal circumstances outside of your control, contact a member of teaching staff as soon as possible before the assessment is due.

If your personal circumstances significantly affect your performance, or preparation, for an exam or eligible written test, refer to the University’s aegrotat or compassionate consideration page https://www.auckland.ac.nz/en/students/academic-information/exams-and-final-results/during-exams/aegrotat-and-compassionate-consideration.html.

This should be done as soon as possible and no later than seven days after the affected test or exam date.

Learning Continuity

In the event of an unexpected disruption we undertake to maintain the continuity and standard of teaching and learning in all your courses throughout the year. If there are unexpected disruptions the University has contingency plans to ensure that access to your course continues and your assessment is fair, and not compromised. Some adjustments may need to be made in emergencies. You will be kept fully informed by your course co-ordinator, and if disruption occurs you should refer to the University Website for information about how to proceed.
