Educational objectives | Students will be offered the knowledge of the most common pollutants in common food products. In particular, sources of pollution and the ways in which these foods can be contaminated will be highlighted. Knowledge will also be provided on the mechanisms proper to the toxic action of these xenobiotics. Finally, practical theoretical notions will be provided on the main methodologies of analysis and quantitation of xenobiotic compounds in biological matrices, in the light of current regulations. |
Prerequisites | Knowledge of inorganic and organic chemistry, and of biochemistry. |
Teaching methods | frontal lectures teams about annual report EFSA seminars about new contaminants |
Other information | news about European contaminazione of Foods, analitical Methods of conto, and new decontamination strategies |

Contents | The course is organized as follows: 1 CFU: GENERAL 1 CFU: ECOPHYSIOLOGY OF MICROORGANISMS IN FOOD 1 CFU: DETERMINATION AND CONTROL OF MICROORGANISMS IN FOOD 1 CFU: OUTLINE OF THE TAXONOMY OF THE MAIN GROUPS OF MICROORGANISMS OF FOOD INTEREST 0.5 CFU: FOOD-BORNE DISEASES 1 CFU: FOOD FERMENTATIONS 0.5 CFU: THE HUMAN MICROBIOTA At the end of each block there are two hours of review of the content provided. The hours of supplementary teaching will be dedicated to helping students in the sedimentation of the contents provided, underlining the connections between the various contents, also in relation to the other module of the integrated course. |
Reference texts | MICROBIOLOGIA ALIMENTARE APPLICATA - Cocolin, Gobbetti & Neviani - Zanichelli The Professor will provide students with educational materials, including lecture presentations and notes on quantitative microbiology, within the Unistudium platform. Materials consistent with the needs of disabled students and/or DSA are provided. |
Educational objectives | The Food Microbiology module contributes to the objectives of the Course by providing students with fundamental skills on the role of microorganisms during the technological processes of food production, including their use in the production of probiotics, prebiotics and functional foods, on legislation and techniques available for microbiological risk analysis and control of the microbiological quality of food. At the end of the course the student will possess a solid knowledge of: a) the role played by microorganisms in foods; b) on the modifications they promote during technological processes; c) on national and community food and health legislation that regulates the microbiological safety of foods; c) on the criteria and parameters of the microbiological risk analysis. This knowledge will be functional to its possible occupational use both in the industrial sector, in food production/processing and distribution companies and in public and private structures responsible for controlling the quality and safety of food. |
Prerequisites | Knowledge of general microbiology, mathematics, chemistry and biochemistry. Ability to connect biological and biotechnological topics derived from biological matter. |
Teaching methods | Lectures, written and oral review. Test for self-evaluation. Numerical exercises. Paths, materials and/or methodologies of assessment consistent with the needs of disabled students and/or DSA are provided. |
Other information | At the beginning of the course, students are encouraged to enrol through Unistudium, not only as the platform where educational materials are uploaded but also as the primary communication channel with the Professor. Regarding office hours, the Professor is available by appointment, to be scheduled in accordance with the other institutional commitments. Students with Specific Learning Disabilities (SLD) who wish to utilize their certification for the completion of the module must notify the SLD coordinator for the Department of Pharmaceutical Sciences. The coordinator will provide all specific instructions to the Professor accordingly. |
Learning verification modality | Lectures, oral reviews. Administration of self-assessment tests. Numerical exercises. Paths, materials and/or assessment methodologies consistent with the needs of disabled and/or DSA students are provided. |
