Overview

Quality management competence represents one of the fundamental skills for future food technologists
The teaching is aimed at:
- Know the mandatory quality management systems
- Know and know how to apply the modern voluntary standards of system and product management
- provide the necessary knowledge to determine the microbiological quality of food;
- Know, apply and optimize the culture conditions of microorganisms in order to be able to give a critical evaluation of the analytical data obtained with the most innovative methods.
- The exam is only oral.
At the end of the course, students will be able to:
- Know the main mandatory and voluntary certifications ..
- Identify and discuss the main problems of the management of quality systems
- Design and build chemical, physical and biological risk assessment plans

Admission requirements

Knowledge of the fundamentals of microbiology and food hygiene

Teaching methods

The course takes place in person and includes frontal teaching with slides prepared by the teacher, and practical exercises in the didactic laboratories. The teaching takes place in Italian. Attendance is not compulsory, but strongly recommended.

Assessment methods

Oral examinations are conducted in the form of cThere will be an oral test, for all, of about 20 min The test will always start with a risk assessment plan Evaluation indicators: - Use knowledge 40%; - Connect knowledge 30%; - Discuss topics 10% - Learn more about the topics 10%

Learning outcomes

1. Knowledge and understanding
Through lectures, exercises and guided tours, the students learn important techniques applied at food microbiology

2. Ability to apply knowledge and understanding
The knowledge learned can bring students to learn the management of food industries.

3. Making judgments
Through the knowledge learned during the course, students will be able to write document to obtain international certification for food industries. .

4. Communication skills
Students will be able to compare their knowledge with colleagues, and transmit it to the information.

5. Learning skills
The activities described allow you to gain the knowledge and methodological tools necessary to be able to independently provide an appropriate update in the future.
