Learning outcomes
The aim is to acquire and to manage the techniques of microbic analysis applicable in a laboratory of analysis for the foods developing the aspects of sensory analysis due to microbial development After having followed the course and participated in the exercises the students will be able to know and to assess the role of virtuous or diminutive microorganisms involved in the phases of ripening of fermented foods, to organize and to perform the analytical controls to the microbic and sensorial characterization of food products and to organize and to compile analysis reports.
