Learning objectives
The course aims to provide students with the knowledge related to the most used modeling and optimization methods in the food industry. The course also aims to provide students with the knowledge related to innovative technologies their applications.
At the end of the course, students will be able to construct, through the use of dedicated software, statistical models capable of describing a production process to optimize operating conditions and predict the properties of the finished product. Students will also be able to evaluate the potential applications in the various food processes of the most innovative technologies.
