Learning Objectives
The aim of the course is to give to the students knowledge about chemical structures and properties of food components. In addition, information will be provided on legislation related to common foods, health foods, functional foods, food supplements and nutraceuticals.
Program
Foods and nutrients. Foods that provide energy and foods that do not provide energy. Energy balance
General Food Law Regulation; Regulation 1924/2006 on nutrition and health claims made on foods.
Lipids: classification and properties; fatty acids, essential fatty acids, trans-fatty acids; triglycerides, glycerophospholipids, waxes, unsaponifiable lipids (principally steroids and terpenes); nutritional properties of lipids; chemical reactions of lipids in foods: isomerisation, hydrolysis, oxidation..
Classification of carbohydrates: monosaccharides, oligosaccharides, polysaccharides. Stereochemistry, nomenclature, reactivity of monosaccharides. Main monosaccharides present in food: D (+) - glucose, D (-) - fructose, D (+) - galactose, L (-) - sorbose. Oligosaccharides: maltose, cellobiose, sucrose, lactose, trehalose. Polysaccharides, starch, dietary fiber, cellulose, hemicelluloses, pectins, gums, glycogen, pectins. Nutritional aspects of carbohydrates; reactions of carbohydrates in acidic/basic environment and during heat treatments.
Proteins: amino acids, peptides, protein structure and classification; essential amino acids and nutritional quality of proteins; foods rich in protein; protein modification during food processing; Maillard reactions. Amino acids supplements
Food supplements: definition, composition, legislation, labeling, purpose and guidelines. Protein, lipid and charbohydrates supplemnts; vitamin and mineral supplements.
Foods for special medical purposes: definition, composition, labeling, legislation and some examples. Demarcation guidelines between food supplements and foods for special medical purposes. Infants formula, baby foods
Functional foods, novel foods: definition and examples
Probiotics, prebiotics and symbiotics: characteritics and examples
Nutraceuticals: definition and examples of nutraceutical products in pharmacies
Vitamins: classification, chemical structure, function and deficiency
Mineral and mineral supplements: function, intake and deficiency of macro- and microelements.
Antioxidants: definition, classification, mechanisms and examples in plant foods (vitamins E, C, A, carotenoids, phenolic derivatives, thiols and glutathione).
Bridging Courses
organic chemisry and food sciences
Learning Achievements (Dublin Descriptors)
1. Knowledge and understanding: Knowledge of molecular composition of food components and their nutritional properties. Acquisition of notions related to the specific composition of dietary products and dietary supplements. Knowledge of the laws and terminology of the discipline
2. Ability to apply knowledge and understanding: Ability to correctly use chemical terminology and structural formulas and to recognize a molecule or a class of molecules by their structure. Ability to recognize the nutritional / physiological properties and the end use of a dietary supplement or nucetrautical, critically posing the problem of scientific support in favor of health and nutritional claims.
3. Communication skills: Ability to expose the results of the studies to the public and in particular the issues of composition, nutritional value of foods, peculiarities and the use of a dietary product and a dietary supplement
4. Making judgments: Ability to make an assessment of the nutritional value of a food or a process of transformation. Evaluation of the suitability of a nutraceutical / food supplement for use by a specific individual.
5. Learning Skills: Ability to synthesize and link the different topics discussed with the related disciplines

Testi di consultazione:
P. Cappelli, V. Vannucchi: Principi di Chimica degli Alimenti, Ed. Zanichelli (Bologna), limitatamente ai capitoli 5-8, 10-16 e 28
P. Cabras, A. Martelli: Chimica degli Alimenti, Ed. Piccin (Padova), limitatamente ai capitoli 5,6,8,13, 21 e 30.
- Assessment
The aim of the exam is to verify at which level the learning objectives previously described have been acquired. The exam consists in an oral comunication to verify the knolewledge's level of the course and the learning of specific vocabulary. In particular will be evaluate the ability of the student to recognize the chemical classes of food components, writing their chemical structures, knowledge and prediction of the reactivity and physical properties of the molecules of interest.
- Disabilità e DSA
Le studentesse e gli studenti che hanno registrato la certificazione di disabilità o la certificazione di DSA presso l'Ufficio Inclusione e diritto allo studio, possono chiedere di utilizzare le mappe concettuali (per parole chiave) durante la prova di esame.
A tal fine, è necessario inviare le mappe, due settimane prima dell’appello di esame, alla o al docente del corso, che ne verificherà la coerenza con le indicazioni delle linee guida di ateneo e potrà chiederne la modifica.
