99855 - Principles of Quality and Technologies Applied to Gastronomic Products

Learning outcomes

At the end of the course, the founding principles of food technologies and basic elements for understanding chemical, physical and sensory qualities will be critically acquired, starting from the knowledge acquired from the basic disciplines, also in relation to sustainability levers.

Course contents

The course is structured into teaching units focusing on sensory analysis of food. It includes lectures and practical exercises. Some of the exercises will be conducted with the support of the course tutor, Dr. Mara Antonia Gagliano.

 

96458 - FOUNDATIONS OF TECHNOLOGY AND QUALITY OF GASTRONOMIC PRODUCTS

(Module 1 – Prof. Tullia Gallina Toschi)

Teaching Units:

Introduction of the lecturer, presentation of course objectives, topics, lessons schedule, teaching materials, and final exam modalities.

Introduction to sensory analysis and historical background.

Vision, smell, taste (new findings), touch and hearing (focus on crunchiness): theory and practical exercises.

Development and implementation of a procedure for defining a sensory profile (QDA). Creation of a profiling sheet, theory and practical testing.

Principles for the selection and training of assessors; physiological and psychological errors. Role and characteristics of the panel leader.

Case study: Sensory analysis of virgin olive oil (with official IOC tasting sheet).

Basics of lipid classification (triglycerides and fatty acids), fat oxidation, frying, and Maillard reaction.

Case study: Identification of the sensory attribute “rancid”, meaning and execution of a ranking test.

Case study: Sensory aspects of some typical PDO and/or PGI products (e.g., extra virgin olive oil, Parmigiano Reggiano).

Discriminant tests: theory and practical exercises (triangle test and duo-trio test).

Sensory analysis and consumer science: qualitative and quantitative affective tests.

Emotions in sensory analysis of food.

Basic principles of food pairing.

Practical Exercises:

Sensory evaluation of PDO cheese samples.

Use and olfactory recognition of essential oils and food-grade spices (with exercises).

Other explanatory sensory exercises in class.

(Module 2 – Prof. Marco Dalla Rosa)

Course introduction. General concepts on food preservation and unit operations in food preparation and stabilization.

History of the food industry and the emergence of food science.

Stability factors of gastronomic products and preserves of plant and animal origin: water activity and mobility in food systems.

Teaching methods

Module 1 (Prof. Tullia Gallina Toschi)

Lectures, practical exercises (in-person or online as scheduled), brainstorming, discussions, in-class learning, group work.

Due to the type of activities and teaching methods used, attendance in this learning activity requires all students of Modules 1 and 2 to complete the e-learning training on health and safety in study and internship environments [https://www.unibo.it/en/services-and-opportunities/health-and-assistance/health-and-safety/health-and-safety-in-study-and-internship-places], as well as participation in Module 3 (specific training on safety and health in study environments). Dates and attendance modalities for Module 3 can be found in the dedicated section of the degree program website.

Module 2 (Prof. Marco Dalla Rosa)

Lectures, use of digital tools / video demonstrations of food/gastronomic procedures, group or individual project on production phases and cultural aspects of a typical product selected by the students.

Assessment methods

Module 1 (Prof. Tullia Gallina Toschi)

Assessment includes a written test (minimum passing grade 18/30) with multiple-choice questions on basic course content, sensory methods, and data analysis, and an oral exam with questions on all course topics. The final grade will be the weighted average of both tests, with the written exam counting for 1/5 of the final score.

The oral exam aims to assess the student's ability to critically present and connect the acquired knowledge, apply logical-deductive reasoning, and use appropriate and correct language. Fundamental elements for the final grade will include proper preparation on course content and participation in the exercises available on the Virtuale platform.

Module 2 (Prof. Marco Dalla Rosa)

During the exam sessions, students will take a test consisting of multiple-choice and open-ended questions (weight: 2/3 multiple choices, 1/3 open-ended; 60% of the module grade). The remaining 40% will be based on a group or individual report analyzing the production stages and cultural aspects of a typical product of the students' choice.

Please note: the final grade for the full 6-credit course will be the average of the grades obtained in the module 1 and module 2.

Students with learning disorders and\or temporary or permanent disabilities: please, contact the office responsible (https://site.unibo.it/studenti-con-disabilita-e-dsa/en/for-students) as soon as possible so that they can propose acceptable adjustments. The request for adaptation must be submitted in advance (15 days before the exam date) to the lecturer, who will assess the appropriateness of the adjustments, taking into account the teaching objectives.

Teaching tools

Projector, PC, whiteboard, video conferencing and material-sharing platforms (EOL/Zoom/Teams).

All materials necessary for exam preparation are available through the recommended textbooks, PowerPoint presentations (not exhaustive for exam purposes) uploaded to the “Studenti Online” platform (https://studenti.unibo.it/sol/welcome.htm), articles provided during lectures and consulted websites and databases. Students are encouraged, when possible, to attend classes with a laptop or tablet.
