This subject aims to develop an awareness in students of recent developments in food
technology and current topics in food safety, and to develop their life-long learning, critical
thinking and communication skills.
Upon completion of this subject, students will be able to
1. recognize current developments in food technology and topics of importance in food safety;
2. define a current problem of food hazard, identify the causes, and recommend possible
3. demonstrate life-long learning, critical thinking and communication skills;
4. appreciate the value of social and national responsibilities as well as professional integrity

School Lunch Box Programme 7 hours
A critical analysis of food poisoning caused by improper handling,
preparation, and storage of school lunch boxes; the responsibility of the
catering service, schools, and teachers.
Total Diet Study 7 hours
TDS as a tool for risk assessment and control in relation to the chronic
dietary exposures to chemicals across the total diet of a population.
Four main topics related to current issues in food safety and food technology are selected for
learning in the subject, with 7 hours allocated to each topic. Keynote Lectures are introduced to
students to cover the main theme of the subject matter. Tutorial will form a significant part of
the teaching and learning strategy of this subject, which aim to foster students’ skills in
analytical power, information acquisition, critical thinking, problem-solving and life-long
learning. Through small-group discussions of relevant topics/issues, tutorials can also enhance
students’ communications skills and their awareness of professional integrity, ethics and social

In this subject students will be concerned with current issues in food safety and technology. The
teaching strategy places emphasis on student-centered and self-directed learning. A group mini-
project forms an important part of the continuous assessment. Students will work in groups on
assigned topics. The group performance and the performance of the individual are assessed
through written and oral reports. The study approach, teamwork involvement, quality of
written reports and performance in oral presentation, including communication skills, form the
basis of assessment for the group project. The continuous assessment is also supplemented by
written tests. A final examination is held at the end of semester. Tests and examination are set
and marked in accordance with the identified learning outcomes and assessment criteria.
Students are required to obtain Grade D or above in both the continuous assessment and the
