Learning Prerequisites

Required courses

Basic chemistry, food chemistry, bio-chemistry

Recommended courses

It is recommended to also follow "Food Biotechnology" by Wilbert Sybesma. Both courses will be given in the spring semester alternating on a 4h weekly basis.

It is also recommended to attend the course "Food chemistry" given by Bernhard Klein igiven n French.

Important concepts to start the course

- Combine knowledge related to chemistry, biochemistry and food technology.

- Interest to learn how chemistry and food processing is applied in food manufacturing to produce safe products with added benefits such as nutrition, taste, and appearance.

- Learn how to select the best suitable technology to achieve the expected target.

Learning Outcomes

By the end of the course, the student must be able to:

• Describe basic principles of food processing
• Describe selected industrial food processes
• Understand chemical changes during food processing
• Understand factors governing food stability
• Describe classical drying processes in food technology
• Describe selected classical preservation methods
• Describe how thermal processes can deliver consumer benefits
• Describe basic safety aspects in food manufacturing

Teaching methods

- Lecture

- Short exercises at the end of each module

- Group or individual presentation on a specific topic (depending on circumstances),

- Exam preparation

Expected student activities

- Attend lectures, interactive approach is appreciated.

- Group work can be presented as a team during the semester.

- A potential visit to a Nestlé research facility will be arranged during the semester (depending on the circumstances).

Assessment methods

Written exam.

Supervision

Office hours	No
Assistants	No
