88276 - Sustainable Food Technologies

Learning outcomes

The objective of this course is to impart knowledge on the food technologies and unit operations having the potential to optimize the preservation of the nutritional and sensory properties, thus ensuring healthy, tasty, and sustainable food, even once it is processed. A deepening will regard the small and medium scale operations (minimal processing) that can be easily used also by farmers, small enterprises and in developing countries, in strict relation with the SDGs 2. A special focus will be on the innovative food technologies able to increase competitiveness, sustainability, circularity and diversity of local and typical foods. The teaching course will benefit of a strict connection with food companies, thanks to the planning of educational visit to plants, lab-scale production laboratories and training placements.

Teaching methods

The course consists in theoretical lessons (32 h) and practical lessons (20 h) for a total of 52 h (6 CFU). Other practical exercises (e.g. brainstorming, working groups) and seminars will be held.

Assessment methods

At the end of the course, students will acquire applied technical knowledge on the relevance of sustainability issues for the food industries, with a focus on some selected food technologies/food chains as case studies. Students will be able to examine, interpret, prioritize and critically analyze the key sustainability factors of food processing, also thanks to practical exercises - e.g. open discussion of research articles -.

The knowledge and skills taught in this course are evaluated as follows: written exam (20 multiple-choice questions) through Esami Online and Zoom or phisically, followed by a compulsory oral exam in Zoom or phisically in the same day (oral questions on the course content), and an optional 3 minutes oral speech focused on a specific topic related to the course content - and discussed in a scientific article - to be presented through a conceptual map or a storytelling video (max 2 points of the final mark).

The teacher can also held the exam only as oral test.

Teaching tools

The teaching material consists of suggested books and presentations of the lessons in .pdf format; the latter will be made available to students in the virtuale.unibo.it platform of the course.

Blackboard, PC and projector are used as tools to support the teaching, as well as chat, microphones, speakers and webcams for the online lessons.

Students will have the possibility to prepare a conceptual map or a storytelling video.
