Course Guide
This Course Guide for SCI S404 explains how the course is organized and how you can best approach the course. The Course Guide has already covered and reviewed course aims and objectives, and it will also review the types of study materials and the IT equipment and skills needed on the course.
Study units
There are five study units in this course. In addition, journal and review articles will be provided as references for the discussion of contemporary issues in food and health sciences.
The five units in the course address nutrition and diet (Unit 1), food safety and regulations (Unit 2), functional foods and health (Unit 3), advanced food technology (Unit 4) and selected topics in contemporary food and nutritional science (Unit 5). Each study unit is broken down into a number of topics. Each topic will provide a list of key concepts, discussion of the topic, and activities and self-test questions. Case studies adopted from HKSAR government will also be discussed. At the end of each unit suggested answers are provided for self-test questions and sometimes activities.
In addition to the study units and assignments, a final examination will be used to assess students' comprehension and understanding of the principles of contemporary food and health sciences.
Unit 1 The roles of nutrition and a healthful diet
Have you ever heard the old adage 'we are what we eat'? In the past, people just knew that consuming food was the only way to survive. But nowadays, especially in developed countries, people believe that different eating habits will shape different kinds of people, and may be the key to disease prevention. Trends in healthcare therefore are moving towards the goal of 'healthy eating'.
Unit 2 Food safety and regulations
In this unit we will focus on food microbiology and food toxicology to convey the biological and chemical aspects of food contamination. We will also discuss strategies that the government and other stakeholders apply to try to maintain public health.
Unit 3 Functional foods and health
This unit introduces you to the role of functional foods in the food industry. It is important to ensure that there is sound scientific evidence for the usefulness of functional foods before putting any claims on labels. Functional foods have been developed for the sake of human health. This unit can help you to understand that the regulation of food labelling and claims is done to ensure that consumers obtain sufficient information before purchasing or consuming and items.
Unit 4 Advanced food processing technology
Have you ever wondered about the refrigerator in your home? It seems that putting food into the fridge to prevent food spoilage is common sense. In fact, it is the best example of how technology becomes part of our daily lives. Of course nowadays food technology is not just limited to refrigeration and freezing. There are many techniques for keeping food fresh and safe. In this unit, we will briefly overview the development of such food technologies. We will also discuss several state-of-art food technologies such as nanotechnology and genetically modified food that may help to accommodate the ever-increasing demands on our food supply.
Unit 5 Selected topics in contemporary food science
After covering nutrition, food safety, functional foods, and technology, students should be equipped with general concepts related to how food science influences our daily lives. But there are many techniques and much knowledge still waiting to be discovered. In this unit, we select several notable topics from previous units and elaborate their specific contents through the use of cases:
Topic 1: Phytochemicals
Topic 2: Food safety
Topic 3: Food technology
Topic 4: Water and health
Topic 5: Integrated topic
