PHISICO-CHEMICAL AND SENSORY ANALYSISAcademic Year 2020/2021 - 3° Year
Credit Value: 7
Scientific field: AGR/15 - Food science and technology
Course Language: Italian
Taught classes: 28 hours
Exercise: 42 hours
Term / Semester: 1°
The aims of the course is to give to students the basics notions on the role of a laboratory of chemical, physical and sensoryal analysis of food. In particular, at the end of the course, the student will be able to choose the appropriate analytical and sensory evaluation methods, to prepare the sample, to carry out the analysis and to perform stoichiometry calculations and to understand the obtained results by comparing them with legal limits and /or quality parameters.
The course includes 28 hours of lectures (or at a distance) and 42 hours of practical exercises, laboratory tests, carrying out exercises, laboratory reports.
The hours of frontal teaching will provide the student the knowledge of the basic notions of the used methods in the chemical, physical and sensory evaluation analysis of food products.
The hours of exercises will allow the student to be able to choose and apply the appropriate analytical and sensory evaluation methods.
If teaching is done in mixed or remote mode, specific changes to the program may need to be made.
Learning assessment may also be carried out on line, should the conditions require it.
