Syllabus
Prerequisites: Knowledge required to follow the teaching refer to:
- Basic knowledge of general, inorganic and organic chemistry and biochemistry
- Basic knowledge of physics.
Target skills and knowledge: Students have to reach a specific knowledge:
-on the organoleptic and functional characteristics of foods and on their measurement.
- on the main classes of molecules and on specific compounds which determine the organoleptic and functional quality of foods, including ingredients and additives.
- on the factors and mechanisms at the different scales (molecular, colloidal and macroscopic) involved in the sensorial and functional properties of raw materials and foods as affected by processing and conservation.

The skills to be acquired are the ability to measure and critically evaluate the organoleptic and functional properties of raw materials, foods, ingredients and additives and to plan their management in the preparation of quality foods.
Examination methods: The final exam consists of a written test containing 26 questions. Some of them with multiple answers, among which the student must indicate the one or ones accurate, and others with short texts to be correctly completed with some words. The questions will cover the entire program and will be aimed at assessing the knowledge gained and the ability to solve problems. The time allowed will be 60 minutes. In exceptional cases, if it proves necessary, the written test will be integrated with an interview. Up to 26 points will be awarded to this test. Further 0-5 points will be awarded on the basis of the results of a group work, carried out during the lecturing time, aimed at deepening a particular topic (assigned to each group by the teacher). This work must be presented in its different parts by the individual students of each group using a power point file (or similar). this will be done during the last hours of the course. The exposure of the individual student will have to last 10 minutes. The final score will be the sum of the grades obtained in the two tests. If the sum exceeds 30 points the "laude" will be attributed.
There are no other ongoing tests.
Assessment criteria: The student competence will be evaluated considering the notions and concepts acquired and on the ability to use them for solving problems, as it will be assessed from the accuracy of the answers given to the written test and the possible interview.
Concerning the presentation of the group work the skills of organizing the presentation, the degree of correctness and of the deepening of the assigned topic, the clarity and the expositive precision and also the communication ability will be considered.
Course unit contents: Introduction to the course. Food quality, complexity and evaluation. Foods as complex systems. Foods as dispersed systems.
Colloids and their properties. Instability and stabilisation of multiphasic food systems. Food surfactants and stabilisers.
Food emulsions. Foams. Turbidity formation. Modification of the physical properties. Food hydrocolloids. Starch, cellulose, pectins, gums. Origin, chemistry and functionality.Substances involved in food color. Mechanisms of color variation. color determination and modification. Substances involved in taste and aroma. Taste and aroma evaluation and mechanisms of formation /modification. The physical-mechanical properties of foods and food quality. Food rheology. Rheological measurements. Rheology and quality of wheat dough. The wheat gluten.
Planned learning activities and teaching methods: The course will be delivered through lectures, using PC supports, and complemented by direct discussion with the students.
At the end of the presentation of each topic online quizzes (for example trough Kahoot, https://kahoot.com/) to verify the degree of attention given during the lessons can be used.
The group works on particular topics to be developed (assigned by the teacher) will be presented by the students in the last phases of the course. After each presentation all the students will be involved in the discussion.
Seminars may be also provided, in Italian and /or in Emglish.
Additional notes about suggested reading: The learning material is the copy of the slides used during the lessons, which will be provided online to students (in PDF format) through the Moodle Platform at https://elearning.unipd.it/scuolaamv/
On the same platform additional useful learning materials, indicated as "Materiale di supporto" will be inserted.
The use of the reference books listed below is recommended.
