Food packaging and logistics

A.Y. 2020/2021
Overall hours
Learning objectives
The course aims to provide students with the knowledge related to the conditioning technologies of food products in order to maintain their quality during the commercial distribution. The course also aims to provide students with the ability to carry out packaging-dependent shelf life studies through procedural and forecasting approaches with the aim of optimizing and making a packaging solution more sustainable.
Expected learning outcomes
At the end of the course, students will be able to choose the appropriate packaging and conditioning system for a food and they will be able to correctly manage shelf life problems with a view to improving the sustainability across the distribution chain.
Course syllabus and organization

Single session

Lesson period
Second semester
Classes will be held on the Microsoft Teams platform and can be followed both in synchrony on the basis of the second semester timetable and asynchronously as they are recorded and left available to students on the same platform and / or on Ariel.
Some lessons, situation permitting, will be in attendance. The methods and criteria for participating in face-to-face lessons, which require a reservation with a special app, will be published in time on the Ariel / etc pages. of teaching, as well as notices relating to any update related to the evolution of the legislation imposed by Covid-19.
