Quality and Genuineness of Milk and Dairy Products
A.Y. 2019/2020
Learning objectives
Describe EU regulations on product labelling and on quality
schemes for agricultural products and foodstuffs.
Supply students with the ability to choose the specific parameters
and to individuate the specific analytical techniques suitable for
the evaluation of chemical, biochemical and technological quality
and/or possible adulterations of different dairy products.
schemes for agricultural products and foodstuffs.
Supply students with the ability to choose the specific parameters
and to individuate the specific analytical techniques suitable for
the evaluation of chemical, biochemical and technological quality
and/or possible adulterations of different dairy products.
Expected learning outcomes
"Employment of the different analytical techniques to highlight
quality aspects of milk and other dairy products. Recognition of
possible adulterations; identification and application of appropriate
analytical techniques to highlight them.
Choice of appropriate parameters and analytical techniques to
evidence specific compositional properties of P.D.O. dairy
products, suitable for their characterization and protection from
imitations."

Lesson period
Second semester
Course syllabus
Legal aspects of quality control; labelling, nutrition and health claims; EU regulation on Protected Geographical Indications and Designations of Origin
Basic determinations for dairy products: proteins (Kjeldahl, Dumas), nitrogen fractions (NCN, NPN), lipids (Röse-Gottlieb, Gerber), lactose (Fehling, HPLC), minerals
Advanced determinations: fatty acids (saturated/unsaturated, GC), heat damage (products of the Maillard reaction); Rapid I.R. techniques: the Milkoscan
Methods for the detection of the most common frauds in the dairy sector
Cheese characterization: free amino acids (IEC) (cheese typicalness), detection of rind addition to grated products), alkaline phosphatase (verification of possible milk heat treatments), lysozyme
