Specific texts for each production process may be recommended during the course.
Educational objectives
TThe aim of the course is to provide students with solid scientific and technological competencies regarding the main transformation processes in the agri-food industry. By the end of the course, students will be able to perform critical analyses and apply problem-solving skills in the sectors of vegetable preserves, beer, flours, bakery products (bread and related goods), meat and meat derivatives, fishery products, coffee, and chocolate.
The programme offers an in-depth exploration of food-processing technologies, product conditioning and distribution systems, process parameters, and the associated unit operations. Special focus will be devoted to process representation techniques using flow-sheets and flow-charts.
The course will also introduce principles related to the management, treatment, and valorisation of by-products from the food industry. For each production process, issues of sustainability and strategies for reducing environmental impact will be addressed.
Prerequisites
Basic knowledge of chemistry, physics, microbiology, and mathematics.
Teaching methods
• Classroom lectures
Delivery of theoretical content through slide presentations, multimedia materials, and demonstrative videos to support the understanding of technological processes and industrial dynamics.
• Practical exercises
Hands-on activities aimed at developing operational skills and enhancing the ability to analyse and solve real-world problems within the agri-food industry.
• Seminars led by industry experts
Thematic sessions conducted by professionals from companies, research institutions, and organizations in the agri-food sector, focusing on innovative topics and real case studies.
• Educational visits to leading companies in the sector
Guided visits to high-profile industrial facilities to observe production processes, adopted technologies, and systems for quality and sustainability management.
Learning verification modality
Oral exam with open-ended questions. The exam will last approximately 30 minutes.

Obiettivi Agenda 2030 per lo sviluppo sostenibile
Food Technology education contributes directly and indirectly to the achievement of several Sustainable Development Goals (SDGs) of the 2030 Agenda, promoting safer, more sustainable, and more efficient food systems.

SDG 3 – Health and Well-being

Application of technologies aimed at food safety.
Reduction of biological, chemical, and physical contamination through good processing practices.
Improvement of food shelf life without compromising quality.

SDG 9 – Business, Innovation, and Infrastructure

Introduction of innovative processing and packaging technologies.
Development of more efficient and technologically advanced industrial systems.
Process digitalization (automation, sensors, in-line controls).

SDG 12 – Responsible Consumption and Production

Sustainable practices in food supply chains.
Valorization of by-products and residual biomass.
Design of sustainable packaging and reduction of waste along the entire supply chain.
Life Cycle Assessment (LCA) and reduction of the environmental footprint of processes.
