Food technology with elements of packaging - mod.2: food packaging
Code: G290CB
Teacher:  Sara Limbo
Year: 
Term: 
CFU: 
CFU subdivision: Lectures: 3
Basic aims:  The course aims to provide usefull tools in testing and evaluating the performances of a packaging material in contact with foods. Performances comprise all the chemical-physical properties of a packaging material that can be related with the food quality and preservation during shelf life. In addition the course gives an overview on the main food packaging operations and technologies usefull to maintain quality and assure safety of a packaged food during its shelf life.
Acquired skills:  The course provides a set of tools to help the Food Technologist test and evaluate the performances of a primary packaging solution.
In particular, the final skills concern:
-knowledge about the packaging functions
-ability in carrying out physical and chemical testing on food packaging materials
-ability in selecting the right packaging solution on the basis of the food properties
-ability in dimensioning the primary package size.
Course contents:  Content summary:
- Food Packaging functions
- Compliance of a packaging material to italian and european regulations
-Chemical and physical performances of a food packaging material
-packaging technologies
