Learning outcomes

The students, at the end of this course, must have the skills to solve the microbiological problems of the food industry, from the evaluation of the  raw material to the final food products, which must satisfy the law regulations. Moreover, the students must be able to solve microbiological problems connected with different industrial processes, such as thermal treatments, or to suggest the best microbial starters in food fermentation.

Course contents

The course will be based on theoretical and on laboratory teachings.

As for theoretical teachings, cases of study regarding the shelf-life and safety of food will be proposed. As regards the shelf-life, the main food spoilage microorganisms, in relation to the matrices considered and the chemical-physical factors characterizing the evaluated foods, will be taken into account. For safety, in relation to the considered matrices, the main foodborne pathogens such as Listeria monocytogenes,Escerichia coli, Samonella, Staphylococcus aureus, Bacillus cereus, Clostridium perfringens, Clostridium botulinum will be taken into consideration. Moreover, the elements necessary to the preparation of experimental plans for improving the shelf-life and safety of food, including the use of Challenge Test, will be also provided.

Moreover, also cases of study for the optimization of the microbial starters to be employed in food fermentation, in relation to the considered food, will be proposed.

For the laboratory teaching, the elements and methods for determining spoilage microorganisms and the search for pathogens in food will be provided. In addition, also the methodology for the set-up of experimental plans will be provided together with the elements for the elaboration of data obtained for predicting the food shelf-life.Moreover, also the application of lactic acid bacteria in food will be considered both during the theorical and the lab  teachings.
