FOOD3002: Chemistry and Biochemistry of Foods

Semester 1, 2023 [Normal day] - Camperdown/Darlington, Sydney

The molecular basis of foods is a critical aspect of food science. FOOD3002 investigates the (bio)chemical properties of food constituents, as well as the interactions between these constituents during food processing, storage, cooking and digestion. You will develop an understanding of the relationship between form and functionality of food constituents and the concept of quality in converting agricultural products into foods. You will gain an appreciation of the relationship between chemical composition and properties of macro-constituents (carbohydrates, proteins, lipids) and micro-constituents (vitamins, minerals, flavour and antinutritional chemicals) and their functions in plant- and animal-based foods. FOOD3002 will enable you to develop research and inquiry skills and an analytical approach to understand the (bio)chemistry of foods and food processing. You will gain experience in laboratory techniques used in industry and research for the analysis of a range of food products, as well as developing information literacy and communication skills, through the preparation of written and in-lab assignments, practical reports and the creation of a short video. On completing this unit, you will be able to describe the (bio)chemical properties of food constituents and demonstrate an understanding of the functionality of these constituents in food processing and nutrition.

Assessment summary

  • Practical class tasks: Each of the six practical classes is associated with a Quiz, for which you are required to provide short and longer answers to a set of 12 questions on the FOOD3002 Canvas website. Each Quiz counts 6% towards final assessment. The Practical Report (Phenolics and Antioxidants) contributes 20% and the Poster (Proteins in Foods) contributes 10% to your final unit mark.

The assessment due-date schedule is below. The two alternative dates for each assessment reflect that students do their practical classes in either odd or even weeks (i.e. each student does fortnightly practical classes). Detailed information for each assessment can be found on Canvas.

  • Final exam: This assessment is compulsory and failure to attend, attempt, or submit will result in the award of an AF grade. If a second replacement exam is required, this exam may be delivered via an alternative assessment method, such as a viva voce (oral exam). The alternative assessment will meet the same learning outcomes as the original exam. The format of the alternative assessment will be determined by the unit coordinator.

Assessment criteria

The University awards common result grades, set out in the Coursework Policy 2014 (Schedule 1).

As a general guide, a high distinction indicates work of an exceptional standard, a distinction a very high standard, a credit a good standard, and a pass an acceptable standard.

See Canvas for a detailed grading tables.

For more information see sydney.edu.au/students/guide-to-grades.

For more information see guide to grades.

Late submission

In accordance with University policy, these penalties apply when written work is submitted after 11:59pm on the due date:

  • Deduction of 5% of the maximum mark for each calendar day after the due date.
  • After ten calendar days late, a mark of zero will be awarded.

This unit has an exception to the standard University policy or supplementary information has been provided by the unit coordinator. This information is displayed below:

10% reduction for each day late

Academic integrity

The Current Student website  provides information on academic integrity and the resources available to all students. The University expects students and staff to act ethically and honestly and will treat all allegations of academic integrity breaches seriously.  

We use similarity detection software to detect potential instances of plagiarism or other forms of academic integrity breach. If such matches indicate evidence of plagiarism or other forms of academic integrity breaches, your teacher is required to report your work for further investigation.

You may only use artificial intelligence and writing assistance tools in assessment tasks if you are permitted to by your unit coordinator, and if you do use them, you must also acknowledge this in your work, either in a footnote or an acknowledgement section.

Studiosity is permitted for postgraduate units unless otherwise indicated by the unit coordinator. The use of this service must be acknowledged in your submission.

Simple extensions

If you encounter a problem submitting your work on time, you may be able to apply for an extension of five calendar days through a simple extension.  The application process will be different depending on the type of assessment and extensions cannot be granted for some assessment types like exams.

Special consideration

If exceptional circumstances mean you can’t complete an assessment, you need consideration for a longer period of time, or if you have essential commitments which impact your performance in an assessment, you may be eligible for special consideration or special arrangements.

Special consideration applications will not be affected by a simple extension application.

Using AI responsibly

Co-created with students, AI in Education includes lots of helpful examples of how students use generative AI tools to support their learning. It explains how generative AI works, the different tools available and how to use them responsibly and productively.

Attendance and class requirements

To successfully complete FOOD3002, students must obtain an overall mark of at least 50/100, including a mark of at least 40% in both the in-semester assessment component (i.e. 24/60) and the exam component (i.e. 16/40).

Study commitment

Typically, there is a minimum expectation of 1.5-2 hours of student effort per week per credit point for units of study offered over a full semester. For a 6 credit point unit, this equates to roughly 120-150 hours of student effort in total.

Learning outcomes are what students know, understand and are able to do on completion of a unit of study. They are aligned with the University's graduate qualities and are assessed as part of the curriculum.

At the completion of this unit, you should be able to:

  • LO1. Understand the industrial context of the chemistry and biochemistry of foods and the major questions that are addressed in this field
  • LO2. Understand food labelling in Australia in terms of the context of the chemistry and biochemistry of foods
  • LO3. Appreciate the range of food sources globally and some of the major contemporary trends that are changing what we eat
  • LO4. Describe the chemistry, biochemistry and processing behaviour of major food constituents: water, carbohydrates, lipids and proteins
  • LO5. Describe the relationship between the molecular structure of constituents and their functionality in foods
  • LO6. Describe the importance of micro-constituents (vitamins, antioxidants; colour and flavour compounds) for the nutritional and sensory quality of foods.
  • LO7. Understand the key aspects of the chemistry and biochemistry of foods for cereal-based foods, meat and dairy foods and fermented foods
  • LO8. Understand and conduct specific laboratory analyses of macro-constituents (water, carbohydrates, lipids and proteins), as well as assays for total phenolics and antioxidants, in foods
