| Educational objectives | The main aim of this teaching is to provide the students with the bases to develop then the study of the food process and the solution of the real problem of the food animal industry. The main acquired knowledge wil be: Principles and applications of the mechanical separation Unit Operation Sedimentation and centrifugation Filtration Theory and application of the heat transfer Pasteurization and sterilization Refrigeration and freezing Principles and applications of the techniques of the thermal separation Unit Operation Evaporation Drying and lyophilisation The main competence will be: Choice and evaluation of the technological parameters for the management of a pasteurization or sterilization Choice and evaluation of the best technique of thermal and mechanical separation respect to the product to treat Optimization of the efficiency of a plant Solution of the problems of the food industry related to the maintenance and transformation. |
| Prerequisites | In order to be able to understand and apply the majority of the techniques described within the course, you must have succesfully passed the exam of chemistry, biochemistry, microbiology. Knowlewdge of these teaching represents a mandattory prerequisite for students planning to follow this course with profit The course is organized as follows: Lectures on all the topics of the course;Pratical exercise in classroom; Technical visit to some pilot plants to examine the equipments using for some food unit operations. |

| Educational objectives | This course is part of the teachings dealing with the production and quality aspects of food of animal origin. The main objective of the course is to provide students with the bases needed to address the study of the production chains of food of animal origin, the importance of the quality of the raw material, the processes of transformation and their implication on the quality and safety of production. The main knowledge acquired will be: Knowledge of production processes and processing of animal products. Knowledge of the main classes of foodstuffs of animal origin (milk and dairy products, meat and meat products, fish products) related to industrial processes and technology; knowledge about food quality, and thethe current legislation of the sector. Knowledge of the techniques of conservation of food of animal origin The main skills are: analyze the different productions identify the stages of production processes evaluate the most suitable parameters for good production and processing |
| Prerequisites | In order to be able to understand and apply the majority of the techniques described within the course, you must have succesfully passed the exam of chemistry, biochemistry, microbiology. Knowlewdge of these teaching represents a mandattory prerequisite for students planning to follow this course with profit |
| Teaching methods | The course is organized as follows: -lectures on all subject of the course -laboratory exercises in the evaluation of the quality of food of animal origin -visits to food industry Students will be divided into groups of 15 for laboratory exercise and into maximum of 20 for visiting food industry |
| Other information | For students with DSA, please contact the teacher |
| Learning verification modality | The exam consists of an oral test. Oral test consists on an interview of about 1 hour long aiming to ascertain the knowledge level and the understanding capability acquired by the student on theoretical and methodological contents as indicated on the program. the oral exam will also test the student communication skill and his autonomy in the organization and exposure of the theoretical topics. At the end of lessons for the module of Food technology phases. It is possible to hold up a written test . The written test consists of the solution of multiple choice test. The test has a duration of no more than 45 minutes and is designed to evaluate the ability to correct apply the theoretical knowledge, the understanding of the issues proposed and the ability to communicate in written form. Than the student has to hold up an oral test consists on an interview of about 45 minutes long aiming to ascertain the knowledge level and the understanding capability acquired by the student on theoretical and methodological contents as indicated on the program of Food technology process. the oral exam will also test the student communication skill and his autonomy in the organization and exposure of the theoretical topics. |
