Knowledge and understanding: the course aims to enable the student to acquire knowledge for a deepen understanding of factors influencing macroscopic properties, stability and microstructure of food products and analytical techniques for the physical characterization of food matrices.
Applying knowledge and understanding: the course aims to make the student able to apply the acquired concepts in food industry for the evaluation and control of physico-chemical stability and structure of foods.
Making judgments: based on the information acquired, the course intends to provide students with the tools useful to critically discuss food structure in relation to their stability, and the choice of proper analytical techniques to study such factors.
Communication skills: the course intends to provide the student with a proper technical-scientific language useful for the communication to the sector experts and not experts.
Learning skills: the course aims to provide the student with the learning skills necessary to study in a widely autonomous way, by searching for case studies that are discussed in class.
Course contents summary
Food as complex and multi-phases systems: crystalline and amorphous status, phases, first and second order phase transitions, phase transition in food, phase transitions in food products and processes.
Food microstructure: the role of main food components in the construction/transformation-destruction of “food structures”, “food structures” assembly, stability and characterization
Physical properties, microstructure and characterization of food products (i.e. dairy products, chocolate, bread, ice cream, .).

The lessons will be organized face-to-face with the possibility to attend the lessons also remotely in synchronous mode (by the Teams platform). During the lessons, face-to-face situations will be alternated with interactive situations.
The lessons will also be usable in asynchronous mode because they will be uploaded on the Elly page of the course.
Seminars and the individual reading and class discussion of scientific articles will be offered.
Assessment methods and criteria
Written exam with open questions that will verify the acquired knowledge on the class subject and the ability to apply such knowledge to the solution of case studies.
In the case of the necessity to integrate with the remote mode due to the persistence of the health emergency, the exams will be carried out through oral questions in a remote mode.
