NFOK13004U Food Science and Culinary Techniques
MSc Programme in Food Innovation and Health
The aim of the course is to use a basic understanding of food chemistry and physics to obtain a scientific approach to gastronomy when various culinary techniques are applied during processing of foods.
The course includes a series of lectures giving a scientific
description of foods as a chemical and physical system. It relates
to proteins, lipids, carbohydrates as well as topics within general
chemistry (inorganic and organic), acid and bases, and interaction
of these components. The course provides an understanding of the
culinary techniques used in the production of foods and highlights
the effects of food processing on the chemical reactions leading to
changes of taste and color as well as the physical properties
of the food in relation to changes in structure and
Practical exercises in preparation of foods will be used as a learning tool to the understanding of culinary techniques. The use of ingredients in various recipes will be evaluated and thereby demonstrate important experimental aspects of food processing and preparation. This will include an introduction to experimental design where recipies and preparations are varied, and the methods of evaluation are identified. Following afterlab discussions will reflect on the outcome of the experiments and correlate it to the scientific principles of exercise.
The lectures and theoretical exercises will demonstrate how food components contributes to the functional properties in dry systems, crystalline states, emulsions, foams and other real food systems. During the practical exercises students will evaluate the different preparations in relation to texture, flavour and color, and explain the outcome according to the theory.
A student who has fulfilled the aim of the course should be able to:
- Describe important chemical reactions and physical changes during processing of foods.
- Describe carbohydrates, lipids and proteins basic function and characteristics in food and point out the effects of culinary processes on physical, chemical and sensory conditions of food components.
- Identify the essential microbiological risks connected with especially low temperature preparation methods and the necessary precautions for handling raw material.
- Describe the effect of physical processes such as pressure treatment and freeze-drying on the structure of food and how physical treatment can be used for developing gastronomic dishes.
- Identify factors of relevance for detection, perception and loss of aroma compounds in different solvents.
- Work in a gastronomic laboratory with specific culinary techniques and follow instructions to obtain a well-defined product.
- Explain the changes in foods taking place during preparation of food from a chemical and a physical point of view.
- Predict the outcome of various preparation methods and recipes based on a simple experimental design.
- Evaluate a complex food and communicate the compositional structure of the product.
- Evaluate the effect of various culinary techniques on the food structure and flavour.
- Ability to plan an experiment which relates to the effect of a culinary technique on the sensory properties of food and evaluate the outcome in relation to the hypothesis
- Ability to communicate scientific topics within food science and culinary techniques in (academic) English
- Integrate scientific disciplines (food chemistry and food physics) in planning and evaluation of practical experiments.
- Cooperate with other students on planning and performing practical exercises including oral evaluation of the theoretical outcome through afterlab discussions at plenary course sessions.
