20440023 - PHYSICAL PROCESSES IN ENOGASTRONOMY

The main objective of the course is the understanding and knowledge of some concepts of physics, using examples taken in the field of culinary applications. In particular, it will be acquired basic math skills and statistics aimed at understanding the physical processes such as: energy, temperature and heat transfer; phases of matter; elasticity; spreading; viscosity and polymers; emulsions and foams.
A part of the course will be devoted to the acquisition of practical skills for working with spreadsheets and translation of numerical data in graphical form (graphs, histograms).

Temperature and Heat.

Temperature and Taste.

Prepare a hot tea and an iced tea. Pour 355 mL of heated water into a kettle into a cup and prepare a hot tea. Measure the initial temperature of the water poured into the cup. This is for drinking, if you like. In a second cup pour 355 mL of heated water into a kettle. Measure the temperature and add 5 ice cubes. As soon as all the ice is melted, measure the temperature again. What should have been the final temperature according to the equation of the week? Compare with the measured one

Attendance

Attendance at the course is mandatory, as required by the Teaching Regulations. Attendance will be recorded with the methodologies made available by the University (QR code).

Type of evaluation

The course is annual, and the lessons take place in the period October-January and in the period March-June, according to what is established in the academic calendar. During the period of suspension of Lessons (January-February) one or two tests will be proposed to verify the skills related to the part of the program called "Data Analysis". At the end of the course (June), in addition to repeating these verification tests, a written test and an oral test will take place. These tests will be repeated in every exam session. The verification tests consist of the creation and interpretation of a graph, accompanied by a brief report on the procedure followed and the results obtained. The written test consists of conducting and solving problems related to the topics listed in the course program. The oral test consists of the presentation and discussion of the dish prepared for the suitability of the Food and Wine Laboratory course. The discussion is about the concepts and skills of Physics behind the realization of the dish.
