Learning objectives
Learning outcomes of the course unit
Knowledge and understanding
The main purpose of the course is to provide theoretical and practical knowledge on emerging food processing and packaging technologies, with particular attention to mild/non-thermal techniques for the preparation of minimally processed food according to the new consumer attitudes.
Making judgements
The student will be able to extend the acquired approach and competences in real food industrial scenario, in order to follow/develop processing and product innovation.
Communication skills
The student will learn the technical terminology on emerging processing and packaging technologies
Learning skills
Student will be able to apply its knowledge in the field of food processing and packaging innovation.
Prerequisites
Prerequisites

Lectures with theoretical background and case studies; visits in food companies.
Assessment methods and criteria
Assessment methods and criteria
The assessment of learning is through a final written exam of 2 hours, during which it is not allowed to use books, notes, computer media.
The written test will contain a series of multiple choice and open questions. The test aims at assess and verify the skills and knowledge acquired in the issues addressed throughout all the course program. The final grade is of thirty.
It is possible to view the performed test and ask for clarification.
