An elementary knowledge of mathematics and physics that is acquired in the majority of secondary schools, is propaedeutic to the teaching.

Development of the course

The course consists of a balance of theoretical lectures (8 ECTS, 72 hours) and other activities, such as classroom practicals (4 ECTS, 36 hours). An e-learning course is available in parallel with the lectures. It includes: the educational material organised in learning units, the materials and instructions for the classroom practicals, self-evaluation tests and results, information, videos of laboratory experiments or supporting theoretic explanations.


Learning outcomes

Knowledge and understanding:

At the end of the course, students will have achieved:

(a) adequate knowledge of principles and fundamentals of the experimental sciences; (b) adequate scientific and methodological knowledge of chemistry; (c) appropriate knowledge and understanding of the fundamental chemical phenomena; (d) knowledge of the main classes of organic compounds and understanding of their reactivity; (e) knowledge of the main organic reactions used in the field of food technology.


Applying knowledge and understanding:

At the end of the course, students will have to:

(a) know how to use the basic knowledge on experimental sciences to approach profitably applicative disciplines; (b) possess the ability to set the mass and energy balances and apply dimensional analysis to verification; (c) understand the chemical principles underlying the instrumental investigation techniques and the laws that describe them; (d) understand the chemical principles underlying the unit operations of food technology and the laws that describe them; (e) be able to use the learned basic knowledge along the entire production chain of food.



Students will obtain: (a) independent judgment for the analysis and understanding of the various chemical phenomena related to food production; (b) the communication skills so they can clearly transfer information, ideas, problem’s solutions and techniques to specialists representative of the various and specific areas involved in the agro-food chains (engineer, biologist, chemist, nutritionist, administrator).

Development of the examination

Learning evaluation methods

The exam consists in a written test which includes two open-ended questions on the two main sections of the course, three stoichiometric exercises on the topics of practicals and 17 multiple choice questions on the whole course content. Oral discussion of the written test.

Optional tests of self-evaluation through exercises and questionnaires are available on the e-learning platform, which aims to provide students useful information about their skill level.


Learning evaluation criteria

The student have to demonstrate a thorough knowledge of the contents of the course, with the use of appropriate lexicon and the ability to apply that knowledge for solving simple problems.


Learning measurement criteria

The final mark is awarded out of thirty. The exam is passed when the grade is equal or greater than 18. It is possible to be awarded with the highest marks with honors (30 cum laude).


Final mark allocation criteria

For each question and exercise a score, that ranges from 0 to 3 points modulated on the completeness and accuracy of the answers, is given. As for the multiple-choice tests 1 point for each correct answer and 0 points for each wrong answer will be assigned. To pass the exam the sum of all scores will not be less than 18. The discussion of the written text can change the total score for a maximum of two points (both positive or negative). Praise is attributed when the score obtained from the previous sum exceeds the value 30 and the student has demonstrated full mastery of the subject.
