Educational objectives
The aim of the course is to provide adequate knowledge on the structure and properties of food constituents, on the mechanisms of the main reactions of alteration and on application of analytical techniques in the quality control of food.The main knowledge acquired will cover: food composition, structure of food constituents, alteration and adulteration of food, quality control of food.The student will be able to apply the acquired knowledge, with the following competence: ability to assess the quality of food, based both on compositional data and on eventual alteration and adulteration, ability to interpret analytical aspects and legislation on food, ability to find and interpret data of the recent literature on food quality.
For a better understanding of the contents and to achieve the objectives of the course, students must have general knowledge on the structure and biosynthetic processes of the main organic macromolecules. Moreover, the knowledge of the main analytical techniques, classical and instrumental, for the qualitative and quantitative determination of inorganic and organic compounds, is indispensable.
Teaching methods
The course is organized as follows:
-lectures on all subjects of the course
-laboratory exercises at Food Chemistry Lab for applications of gas chromatography in food analysis. Students will be divided into groups (maximum 12 students per group) and there will be two tutorials of 2 hours each.
Other information
Course attendance is strongly recommended.
Learning verification modality
The exam consists of an oral test, an interview of about 30-40 minutes long aiming to ascertain the knowledge level and the understanding reached by the student on the topics presented in class and listed in the program.The questions will focus on the structure of food constituents, the mechanisms of modification of these components, the composition and legislation of the main foods, the analytical aspects necessary to define food quality.Overall, the oral test will check communication skills of the student with properties of language, the ability to apply the acquired skills and develop solutions on their own.
