FOOD TECHNOLOGY
Module QUALITY MANAGEMENT

Academic Year 2022/2023 - Teacher: ROSA PALMERI

Expected Learning Outcomes

The course aims to provide a description of Unit Operations and the main processes of catering and organized distribution, as well as the chemical-physical phenomena and transformations that occur in food. The course focuses on the problems and interactions that exist between product, process and storage within the catering production processes. In particular, material and energy balances applied to the main production processes characteristic of the Mediterranean area, the transport of bound heat and the main conservation techniques, the shelf life of food, cooking techniques, the structuring of ready meals and menus. Finally, the course will focus on the production processes and issues related to the main productions of the Mediterranean area, such as wine, milk, oil and bakery products through case studies applied to catering.

The course aims to provide students with: the knowledge necessary to understand and face the problems in the transformation and production of a food. In particular, attention will be focused on the interactions between raw materials and transformation processes to obtain a high quality food

Learning Assessment

Learning Assessment Procedures

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.
