Learning outcomes

At the end of the course, the student knows the commodity and quality characteristics of the main foods, their processes and how much these affect, in terms of quali and quantitative modifications, their nutritional properties.

Course contents

The COMMODITY SCIENCE AND FOOD TECHNOLOGY (4 CFU) course is structured in didactic units dealing with the technological and commodity aspects of food. The course includes lectures and exercises. Some of the practical and sensoty exercises will be carried out with the support of Dr. Matilde Tura, Dr, Rosalba Roccatello and Dr. Erica Bensmail.

Teaching methods

Lectures, exercises (in presence or remotely/online), brainstormings, discussions, learning in class, working groups.

In consideration of the types of activities and teaching methods adopted, the attendance of this training activity requires the performance of all students of Modules 1 and 2 in e-learning mode [https://www.unibo.it/en/services-and-opportunities/health-and-assistance/health-and-safety/online-course-on-health-and-safety-in-study-and-internship-areas] and the participation in Module 3 of specific training on safety and health in the places of study. Information on the date and method of attendance of module 3 can be consulted in the section of the study program website.

Assessment methods

Oral examination, evaluation of exercises and ongoing learning.

Key elements for the final grade include:

adequate preparation on course content and in-class exercises (available on the University platform “Virtuale”);
proper use of terminology and scientific language;
critical thinking and analytical skills.

N.B. The exam of the two modules of the Chemistry of Food and Food Technology (C.I.) course will be held on the same day.

Students with specific learning disorders (SLD) or temporary/permanent disabilities are strongly encouraged to contact the University support service in advance (https://site.unibo.it/studenti-con-disabilita-e-dsa/en ).
