FOODSCI 202 : Food Preservation


2022 Semester Two (1225) (15 POINTS)

Course Prescription

Food is spoilt by microbiological, chemical, biochemical and physical processes. It is important to understand the mechanism of spoilage caused by each of these processes in order to prevent or minimise such degradation. This course includes fundamental principles covering the preservation and processing of different food products. The principles involved in the development of food safety and HACCP programmes, as well as New Zealand food laws are also covered.

Course Overview

The course is designed for the stage 2 students whose major is Food Science and Nutrition. It will lead to both Food Science and Nutrition pathways. The course is a prerequisite for FOODSCI 306. This course is good preparation for anyone wanting to do postgraduate study in Food Science. The skills developed in this course are particularly useful for those wishing to have a career in food processing industries. The course introduces students to the multifaceted nature of food science and technology with a focus on the interplay between food science, technology , engineering and nutrition for the purpose of food preservation. Legislative and regulatory aspects related to food preservation and production are also be introduced. Concepts will be illustrated using real food systems with a focus on different types of food processing methods relevant to food industries. There are 3 lectures per week and one laboratory per fortnight which are designed to complement the lectures to increase students’ understanding of food processing and preservation.   The topics are delivered by Fan Zhu,  Kang Huang,   Peter Swedlund from the Faculty of Science, and  Meng Wai Woo from the Faculty of Engineering. This is a core course for BSc majoring in Food Science students.  The topics covered in the six blocks include: Shelf life; Fruit and Vegetable postharvest; Rheology and thermodynamic laws; Oil refining; Packaging; Meat and dairy processing; Food safety aspects of food preservation;  Food processes and changes in food properties.

  2. Describe and explain basic principles of several food processing and preservation methods including thermal processing, freezing, dehydration, fermentation, high pressure processing, pulsed electric field and pulsed light processing, and irradiation. (Capability 1, 2, 3 and 5)
  3. Describe and explain the principles of packaging including controlled atmosphere and modified atmosphere packaging. Understand the basis for selecting some important packaging materials use for different packaging systems and some of their important properties. (Capability 1, 2, 3, 4 and 5)
  4. Derive, analyse and solve hands-on laboratory experience and questions in food preservation and processing and ability to work in teams. (Capability 1, 2, 3, 4, 5 and 6)
  5. Be able to solve and be proficient with shelf life determinations and able to predict shelf life using accelerated shelf life tests. (Capability 1, 2, 3 and 5)
  6. Describe and apply the principles of operation, and the key process parameters for microbial safety and quality of juice and beverages and other food products. (Capability 1, 2, 3 and 5)

Delivery Mode

Campus Experience

Attendance is required at scheduled activities including labs to complete components of the course.
Lectures will be available as recordings. Other learning activities including labs will be available as recordings for off-shore students.
The course will not include live online events.
Attendance on campus is required for the test/exam.
The activities for the course are scheduled as a standard weekly timetable.

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.

There is no prescribed text.  
Lecture notes will be provided as pdf files prior to classes and students are advised to print these prior to class to allow for annotation.  
Lectures will be recorded for those who are not able to attend.  Suggested readings and other activities will provided with each block.

Student Feedback

During the course Class Representatives in each class can take feedback to the staff responsible for the course and staff-student consultative committees.

At the end of the course 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.

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

Academic Integrity

The University of Auckland will not tolerate cheating, or assisting others to cheat, and views cheating in coursework 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. This requirement also applies to sources on the internet. A student's assessed work may be reviewed against online source material using computerised detection mechanisms.
