FOOD PACKAGING

Academic Year 2024/2025 - Teacher: Giuseppe MURATORE

Expected Learning Outcomes

The course aims to provide the essential knowledge to connect the notions acquired in other disciplines with the particular problems of conditioning technologies and distribution of food products; The course also aims to provide the knowledge and procedures for the study of the shelf life of food products.

At the end of the course students will be able to make, and / or direct, conscious and effective choices of food packaging and make a packaging solution more sustainable.

Expected learning outcomes:

Knowledge and understanding: Knowledge of the particular problems and technical requirements of the food packaging industry;

Ability to apply knowledge and understanding: Ability to apply acquired knowledge in the search for suitable technologies for solving problems related to the design and management of packaging of agri-food products;

Independent judgment: Ability to critically select the best technical and management solutions applicable to different agro-industries and present the results of an elaborated technical solution;

Communication skills: Ability to interact with industry technicians, suppliers and agro-industrial entrepreneurs to solve a relevant technical problem in the food packaging sector;

Learning skills: Ability to independently study scientific literature in the field and critically evaluate data and technical information.

Course Structure

Lectures (21 hours - 3 CFU) and exercises (42 hours - 3 CFU) (classroom and company), also on line.

If teaching is done in mixed or remote mode, specific changes to the program may need to be made.

During the course monographic articles will be given from magazines in the sector, autonomous and guided research will be carried out on websites and specific texts for the food packaging sector will be consulted

Information for students with disabilities and/or DSA. As a guarantee of equal opportunities and in compliance with current laws, interested students can ask for a personal interview in order to plan any compensatory and/or dispensatory measures, based on their specific needs and on teaching objectives of the discipline. It is also possible to ask the departmental contacts of CInAP (Center for Active and Participatory Inclusion - Services for Disabilities and/or DSAs), in the persons of professors Giovanna Tropea Garzia and Anna De Angelis.

Required Prerequisites

Basic knowledge of Food Technologies, Food Microbiology, Biochemistry, Chemistry.

Attendance of Lessons

Strongly recommended, but not mandatory

Contribution of education to the goals of the 2030 Agenda for Sustainable Development

GOAL 12: RESPONSIBLE CONSUMPTION AND PRODUCTION

12.3 By 2030, halve global per capita food waste at retail and consumer levels and reduce food losses along production and supply chains, including post-harvest losses

12.5 By 2030, substantially reduce waste generation through prevention, reduction, recycling and reuse

12.6 Encourage companies, especially large and transnational companies, to adopt sustainable practices and integrate sustainability information in their regular reports

Mode: 

- lecture

- dedicated seminar
