| Learning objective | To become acquainted with important methods of food analysis. | ||||
| Content | Analysis of important constituents (carbohydrates, fat, protein, water) of food raw materials and food products. Methods: Titrimetry, spectrometry (UV/VIS), chromatography (TLC, HPLC, GC), enzymatic analysis, Kjeldahl analysis. | ||||
| Lecture notes | All material is available via the Moodle platform. | ||||
| Prerequisites / Notice | Prerequisites: 1. Attendance of the course Food Chemistry I (752-1000-00L). 2. Attendance of the course Food Analysis I (752-1101-00L) in parallel to the lab course. Performance assessment consists of 5 parts: - Attendance of the introductory lectures in the first week of the semester (Monday and Tuesday) - Attendance and active participation in the laboratory courses (also in the last week of the semester) - Successful execution of the test experiment at the end of the semester - Peer-review of lab reports from other students - Timely submission of the worksheets and lab reports (average of graded reports must be sufficient) General Information: The course will be run in two groups, which alternate (in general) on a two week cycle. As a general rule, each student should attend the course every other week on Monday and Tuesday. The weeks in between are reserved for independent preparation of the next experiments and report writing as well as reviewing reports from colleagues. There may be deviations from this two weekly schedule due to public holidays. Therefore it can happen that students need to participate in the course in two consecutive weeks. Students will be divided in the two groups during the first week of the semester and will then receive the definitive personal schedule for the course. Absences during the semester due to military service, personal holidays etc. cannot be accommodated. | ||||
| 752-1022-00L | Selected Topics in Food Chemistry | 3 credits | 2G | L. Nyström, M. Erzinger | |
| Abstract | This course is centered in cereal chemistry: main chemical components related to physicochemical, technological and nutritional properties of grain products. | ||||
| Learning objective | The main goal of the course are: Understand the chemical composition and properties of cereal grains as raw materials for food, changes in composition during grain processing, and the effects of both on the nutritional properties of grain based products, such as breads, pasta, and breakfast cereals. | ||||
| Content | The course covers fundamental and modern aspects of cereal chemistry: composition of grains, physicochemical properties of main grain components (starch, proteins, fibres, lipids), and their effects on technological and nutritional properties of cereal grain products. Focus is put on chemical reactions and changes during common food processing (dough making, baking, extrusion, fermentation), reflecting also their effects on the nutritional and sensory properties of grain products. Furthermore, a special emphasis is put on dietary fibres and related phytochemicals in grains: Different dietary fibre compounds found in cereals and cereal products (cellulose, arabinoxylan, beta-glucan, resistant starch etc.), co-passengers of dietary fibre (phenolic acids, plant sterols, tocols, folates, alkylresorcinols, avenanthramides), factors affecting their levels in foods, and methods used for the analysis of their content and composition. | ||||
