FOOD PROCESSING

The course aims to transfer the theoretical and applicative knowledge concerning the main food processing technologies with particular reference to the productions of the Mediterranean area. The course focuses on the problems and interactions that exist between product, process and storage in the context of food production in order to provide a global knowledge of the processes and technologies used in food processing. In particular, attention will be focused on the interactions between raw materials and transformation processes to obtain a high quality food

In relation to the Dublin Descriptors 1 (knowledge and understanding) and 2 (ability to apply knowledge and understanding), the course aims to provide students with the necessary knowledge to understand and address the problems in the processing and production of a food. In relation to the Dublin Descriptors 3 (autonomy of judgment), 4 (communication skills) and 5 (learning ability) the teaching aims to make students acquire the ability to analyze and understand food transformation processes and the critical points of the process in order to be able to propose corrective actions for the optimization of the process.

The course includes n. 35 hours frontal (or remote) and n. 28 hours of exercises (exercises in the company in person or remotely, specific in-depth seminars on the problems of the food supply chains with discussion of case studies)

Lectures and exercises (in the classroom and in the company), also online

If the teaching is carried out in a mixed mode or online, it may be necessary to introduce specific changes with respect to the program

Information for students with disabilities and / or SLD

To guarantee equal opportunities and in compliance with the laws in force, interested students can ask for a personal interview in order to plan any compensatory and / or dispensatory measures, based on the didactic objectives and specific needs.

It is also possible to contact the CInAP referent teachers (Center for Active and Participated Integration - Services for Disabilities and / or SLD) of our Department, prof. Anna De Angelis.

Lecture notes and material for consultation and reading will be available on the Studium.Unict.it platform

The final exam consists of a written and oral test, which include the discussion of the exercises related to mass and energy balances, heat exchange and evaluation of shelf life. The oral exam will be completed with the discussion of the remaining topics included in the program. The final mark will be the weighted average of the written and oral marks. The ability to solve numerical problems will be evaluated through the application of the appropriate mathematical and physical relationships; the ability to describe physical and biological phenomena, principles of organization and management of productive contexts, with properties of language, analytical and synthesis skills.

Whenever possible, intermediate written tests will be carried out, relating to exercises relating to mass and energy balances, heat exchange and evaluation of shelf life. Passing the mid-term test allows you to take a final exam which excludes the topics covered by the test, the grade of the mid-term exam contributes to the final grade, in a weighted way.
