Sustainability of Food Production
A.Y. 2025/2026
Learning objectives
This course gives an overview of the holistic approach in sustainable food processing via the consideration of the total value chain. The aim of the course is to provide a knowledge of the food system for aspects of environmental alerts for food production. Cognitive tools will be provided for a sustainable approach to food processes, up to consumption, to promote "green" food production protocols, with respect for human health and favoring simplified diets. It is a goal of teaching that students recognize the challenges and risks of environmental issues related to the food processing chain and are able understand possible technological interventions to promote food security. The imparted training will enable students to identify critical issues for the benefits and disadvantages of technological actions and policies to mitigate resilience to the impacts of environmental change on food systems. New technologies (e.g., through novel engineering, equipment, processing, and packaging policy) to address emerging environmental challenges will be presented and criteria for sustainable diets will be formulated.
Expected learning outcomes
At the end of the course the student will possess the necessary knowledge to facilitate technology transfer and to support the technological aspect of food policy decision-making actions for sustainability. The acquired competences will allow the student to have critical and judgment skills on operational decisions in the food system with regard to the identification of new engines of sustainable growth of primary production ("nutrition sensitive agriculture"), of post-harvest technologies of fresh products, including the "novel technologies", of the reduction of waste in the food supply chain, of new "clean" food ingredients and with a health value and recovery of functional components ("green chemicals") from food waste.

Course syllabus
-Food system and technical aspects of sustainability policy: agri-food value chain; SDG 12; Farm-to-Fork strategy; Circular Economy Action Plan; PPWR; CSR and competitiveness.
-Foundations of food science and technology for sustainability: spoilage, HACCP protocols, water activity and shelf-life; microbial inhibition and "killing" operations; innovative thermal and non-thermal technologies (HPP, PEF, cold plasma).
-Packaging, sustainable packaging, and digital traceability: conventional and bio-based materials, active/intelligent solutions; eco-design; end-of-life and recycling; blockchain and IoT for traceability.
-Food waste and loss: quantification, supply-chain causes, EU 2030 targets; prevention and reduction techniques—interactive case study.
-By-product valorisation: up-cycling of agricultural residues and side-streams (fibre, proteins, "green chemicals"); biorefinery models.
-Water- and energy-efficiency in processing: Best Available Technologies (BAT) and best practices for CIP, heat exchangers, heat- and water-recovery systems to cut environmental impact and boost efficiency.
-Sustainable diets and consumer communication: diets for health and planet, labelling (Nutri-Score, Eco-Score), ultra-processed foods.

Prerequisites for admission
Students enrolling in the course should already possess basic knowledge of general chemistry and natural compounds, along with foundational economic concepts of agri-food sustainability.
Teaching methods
The course blends lectures, discussions, and hands-on group work. Each team undertakes a project—approved in advance with the instructor—that requires direct engagement with relevant stakeholders and is assigned at the start of the term. The project must be finished by the end of the course, and every student will discuss their individual contribution during the exam. Because the project is formative, steady attendance and active, constructive interaction with the instructor are essential.
Teaching Resources
The lecture slides are available on MY ARIEL-UNIMI, and the instructor supplies additional scientific papers for further study. Any lecture notes produced by unaffiliated authors and not approved by the instructor are not recognized as official course materials.
Assessment methods and Criteria
Assessment method
The course is evaluated through a single, final oral examination covering the material taught in the lectures; there is no in-itinere assessment.
Exam structure:
Discussion of course content: two questions are asked—one selected by the instructor and one on a syllabus topic chosen by the student.
After this discussion is passed, a final question focuses on the project or exercise developed during the course.
Grading criteria:
Marks are awarded for the accuracy of answers, precision of language, and—where relevant—the ability to integrate interdisciplinary perspectives.
Scale:
The exam is graded out of thirty.
Materials:
All technical tables or reference sheets needed to answer the questions will be provided by the instructor.
