In order to attend the module of Technologies and quality control of functional foods the student must have good knowledge of chemistry and microbiology of food.
In order to attend the module of Pharmaceutics and Quality Control the student have to master the basic concepts related to Organic Chemistry, Biochemistry and General Physiology.
Course unit content
The teaching module of Technologies and Quality Control of Functional Foods aims to address the main unit operations of the food industry with exemplary and applicative references to the case of production processes for obtaining food products and functional ingredients.
The unit operations in the context of industrial process technologies will be studied through a multidisciplinary approach, in order to break down the technological problems into aspects related to the chemical, nutritional, microbiological, physical and sensorial quality of functional products. In this context, the course will deal with the functionality of the ingredients that can be used in food formulations not only from a nutritional, but also from a technological point of view.
Furthermore, a part of the course will address issues related to the aspects related to the quality control of the product and the process.
The course is divided into two parts:
- An introduction part that will deal in a general way aspects related to the factors that affect the shelf life and the quality of food and the differences between functional foods, food supplements and foods for special medical purposes.
- A part related to the criteria for choosing ingredients for the design of functional foods and the main unit operations of the food industry with application and example references to functional products. Moreover, self-control plans, quality assurance, voluntary regulations and analytical systems for quality control at an industrial level and for product’s optimization will also be covered.
The Module of Pharmaceutics and Quality Control will provide the fundamental concepts on the design of dietary supplements and medical foods, on the manufacturing of dosage forms and their use by consumers.
The Module, delivered in presence is divided in three parts:
- An introduction dealing with the differences between medicinal products, dietary supplements and medical foods, the basic concepts of biopharmaceutics and pharmacokinetics with special focus on the oral route of administration;
- A general part dedicated to quality, good manufacturing practices (GMP), excipients and basic pharmaceutical operations (milling, mixing, dissolution, filtration, sterilization and drying);
- A section dedicated to specific dosage forms (powder, granules, tablets, capsules etc.) to their manufacturing and quality control according to the current norm, including stability studies and the requirements related to packaging.

Teaching methods
The module of Technologies and quality control of functional foods is organized through lectures, possibly integrated with seminars, articles and video material useful for understanding and deepening the topics covered.
The slides of the lessons, which are an integral part of the teaching material, as well as all the supplementary teaching material, will be uploaded weekly on the Elly platform of the course.
The Pharmaceutics and Quality Control module will be carried out in presence using slides projection, integrated with scientific papers, documents and online materials useful for the understanding and enrichment of the subject discussed in class (uploaded on the portal Elly).
Students will be constantly reminded the appropriate technical language, exposed to real-life examples, invited to understand the underlying connections between different parts of the course and other subjects and will be stimulated to actively participate to the lectures with interactive discussions.
Assessment methods and criteria
The summative evaluation of the knowledge acquired is made through a written exam, made of two partials relative to the two modules. The student should, then, after online enrollment:
a) pass a written exam during the official dates established by the Dipartimento di Scienze degli Alimenti e del Farmaco (Module of Functional foods technologies and quality control, weight 50% of the overall grade);
b) pass a written exam during the official dates established by the Dipartimento di Scienze degli Alimenti e del Farmaco (Module of Pharmaceutics and quality assurance, weight 50% of the overall grade).
For the module of Technologies and quality control of functional foods, validation of learning will be carried out with a written exam consisting of a first part with closed answers (30 minutes of time for 31 questions) and a second part with an open question (30 minutes of time). Both parts will be evaluated on a scale of marks out of thirty; the average of the votes of the two parts, rounded up, will make up the final vote.
Through the test, the theoretical knowledge gained through the study of the subject, the connection and reasoning skills between the subjects under study and the writing skills will be evaluated using an adequate and appropriate technical-scientific terminology.
Honors will be reserved for candidates who have gained the maximum score on both parts and who have shown an excellent command of the technical-scientific vocabulary and an excellent ability to connect and reason between the topics.
For the module of Pharmaceutics and Quality Control the overall evaluation of the student preparation will be carried out in a written test of 18 multiple choice questions (0-1 point/answer) and 4 open answer questions (0-3 points/answer). Up to 2 points will be given for the communication skills of the student.
The aim of the evaluation is the assessment of:
- student knowledge and understanding of the subject studied
- student judgement and understanding of the interconnections between different aspects of the course
- student communication skills in technical and scientific language;
- student ability to apply and use the knowledge acquired with independent and competent reasoning.
Students can register online for the exam using portal ESSE3 in the sessions available on the official exams calendar of the Department of Food and Drug.
The results of the exam will be published on ESSE3 portal within one week from the date of the exam. Students will be allowed to view their tests, by appointment with the teachers
