Abstract

Descriptive chemistry of food constituents (focus on structure-function relationships).Reactions which affect the colour, flavour, texture, and the nutritional value of food raw materials and food products during processing, storage and preparation in a positive or in a negative way (lipid oxidation, Maillard reaction, enzymatic browning).

Objective

 Be able to draw chemical structures of the main ingredients, recognize functional groups in the structures and explain their properties.  Understand foods as complex systems and be able to make connections between chemical structures, chemical reactions and their influence on quality.  Recognize chemical reactions of lipid oxidation, Maillard reaction and enzymatic reactions and be able to formulate them themselves.

Content

Descriptive chemistry of food constituents (focus on structure-function relationships). Reactions which affect the colour, flavour, texture, and the nutritional value of food raw materials and food products during processing, storage and preparation in a positive or in a negative way (lipid oxidation, Maillard reaction, enzymatic browning). Links to food analysis, food processing, and nutrition. Topics: - Lipid oxidation, Maillard reaction, structural proteins/enzymes - Food as complex systems - Chemical reactions and reaction mechanisms - Selected (possibly changing) food chemistry topics (e.g. sweeteners, polysaccharides, from olive to margarine, etc.) The lectures Food Chemistry I and Food Chemistry II constitute a unit.

Die Gesamtnote setzt sich zusammen aus der Leistung der Semesterendprüfung (80%) sowie der selbständig zu bearbeitenden Aufgaben (20%). Diese Aufgaben sind ein obligatorisches Leistungselement. Ohne Absolvierung der Aufgaben wird für das Leistungselement die Note 1 erteilt (20% der Gesamtnote). Zusätzlich kann das erfolgreiche Lösen von zusätzlichen Lernelementen zur Erhöhung der Gesamtnote im Umfang von maximal 0.25 Notenpunkten führen.
