Small groups of students will perform the analyses of food samples regarding relevant parameters (e.g., meat and meat products, milk and dairy products, egg, cereals, soy beans, etc.). Various aspects of food chemistry are to be used (e.g., water content using an oven method; fatty acid profile by GC; lactose by enzymatic test; protein analysis using electrophoresis).
Enzymatic analysis of foods (e.g., ascorbic acid, organic acids, sugars, starch, amino acids, urea, cholesterol); and/or
Electrophoretic analysis (PAGE, SDS-PAGE, IEF) of proteins in foods (e.g., meat, milk, egg, cereal or soya products)
Physico-chemical parameters (e.g. dry matter, fat content, fat characterization indices, protein content, carbohydrates, ash, density, freezing point); and/or
Chromatographic analysis (GLC, HPLC, TLC) of lipids in foods (e.g., fatty acid profiles, triglycerides, phospholipids, vitamins)
- Previous knowledge expected
Basic knowledge in chemical and food chemistry laboratory (e.g., accurate pipetting with micropipettes and graduated pipettes; handling of analytical balances; principle and operation of photometers) as well as understanding of the fundamental aspects of "laboratory safety" (e.g., safe handling of chemicals, cleanliness and order, to avoid endangering persons in the chemical laboratory) !!!
==> If these prerequisites are not fulfilled, a safe and efficient work in this Practical Course is definitely NOT possible !!!
- Objective (expected results of study and acquired competences)
After having successfully completed this practical course, students will be familiar with the principles of chemical food analyses, and are able to apply this knowledge in practice. They learn to apply selected practical analytical procedures and methods. They know classical methods (e.g., Kjeldahl, Soxhlet, oven methods, and photometry) as well as modern techniques (e.g., chromatography, AAS, electrophoresis, polymerase chain reaction) that are used to analyse the gross food composition (e.g., dry mass, protein, fat, carbohydrates, ash, mineral, vitamins). Students will have basic knowledge and competence in the area of chemical food analysis, and will be able to use these skills in testing and assessment of foods.
