The course aims to provide students with the understanding of the physical principles related to the unit operations of the food industry and their peculiar balance equations with particular reference to heat treatments for pasteurization and sterilization operations; drying and dehydration; freezing and freeze-drying.
The course aims to provide students with the concepts related to the processes, technologies and plants of the food industry, deepening the relative unit operations. The course also provides the elements for the management of food systems with particular reference to the quality and safety of the product.
Attendance and active participation in the proposed training activities (lectures, numerical and laboratory exercises) and individual study will allow the student to understand the fundamentals of food preservation technologies and related unit operations such as:
For a successful learning basic knowledge of chemistry, organic chemistry and chemical plants are required, but no formal pre-requisites are mandatory.
The course consists of lectures, numerical and laboratory exercises, educational visits to food industries aimed at encouraging the learning and discussion of specific examples of food and process engineering applications.
The transversal competences in terms of autonomy in making a decision will be acquired through the numerical and laboratory exercises to be carried out in the classroom also as group work.
The module program consists in the presentation and discussion of the following topics:
The teaching material used during the lessons will be provided to the students during the course. The notes taken during the lessons and the material provided are sufficient for the preparation of the exam, but the following books are suggested as supporting texts.
P.J. Fellows, Food processing technology, Ellis Horwood, New York, 1988
R.T. Toledo, Fundamentals of food process engineering, AVI Publ. Com., Westport, 1980
A.S. Foust et al., The principles of the unitary operations, John Wiley & Sons, New York, 1980
Office hours: Students could discuss with the teachers by fixing an appointment.

All class schedules are posted on the EasyAcademy portal.
The exam consists of an oral discussion about all the topics of the course.
Three exam sessions will be available for the 'winter' session (January, February and during the educational break provided by the Polytechnic School at Easter) and 4 calls for the 'summer' session (June, July, September and during the autumn break provided by the Polytechnic School). No extraordinary sessions will be provided outside the periods indicated by the Polytechnic School, except for students who have not included in the study plan training activities in the current academic year.
Details on how to prepare for the exam and the degree of knowledge of each topic will be given during the lessons. The exam aims to verify the ability to apply the theoretical contents provided during the course to general or specific cases of technological interest and to critically analyze problems. The quality of the exposure, the correct use of technical terminology and the critical reasoning ability will also be assessed.
