Are you a professional in the food industry and do you want to strengthen your expertise and knowledge about how physical and chemical aspects influence the stability of products?
In this online master's course we will mainly focus on the product categories ice cream, bread and beer and how their physical and chemical properties are linked to the product stability, shelf-life and texture (sensorial properties). Since this online course is part-time, you will be able to combine study and work and enhance your career.
Content of the course
The course will focus on science behind different products categories, in terms of textural and flavour aspects. These aspects are introduced in relation to developments in industry and restaurants. In this course we mainly focus on the product categories chocolate, bread and beer. The course includes both physical and chemical aspects of these products.
- different physical phenomena are described, such as fat crystallization, sugar crystallinity, rheology of dispersions, fat migration, phase transitions, diffusion, and rheology. These phenomena are discussed to understand the preparation, the stability and the shelf-life of the foods, which may be an important aspect for restaurants or industry
- for the different food products, the role of the ingredients are discussed with respect to the structure of the food (emulsion, dispersion, foam, interface)
- the structure of the food is related to textural (sensorial properties) of the different food products. the scientific understanding of the systems will allow you to change the structure of the food and thereby control the sensory perception of the food
- chemical aspects important to understand the sensory perception are discussed, such as astringency and bitterness. These are discussed in relation to the sensors present in our mouth to detect certain compounds
- different ingredients related to sensory detection are discussed and the interactions between different compounds in food. The effect of time or processing conditions will be discussed and how these can alter the sensory perception
- the ingredients are discussed in terms of their functionality in different food products. The scientific understanding of these systems will allow you to control the stability of the products
The activities during this course comprise: knowledge clips, self-study of the material, and digital case studies. The knowledge clips provide the theoretical background of the different topics. This will be complimented with written material. The case studies follow the knowledge gained from the knowledge clips and written material. The case studies are self-directing and feedback will provided during the exercises.
You will learn to
- Identify the physical phenomena and understand the mechanisms of action that play a role in products such as chocolate and bakery products.
- Understand the mechanisms behind important taste modalities (bitter, astringent).
- Be able to link structural aspects to texture and sensory perception.
- Be able to link taste modalities to sensory perception.
- Be able to analyse chemical and physical data to link the food ingredients to their function.
When you want to learn more about ingredient functionality, other courses are interesting for you too! You can deepen your knowledge in a specific career field, without following a complete master's programme. You can register for any combination, but these are our suggestions:
- Advanced Molecular Gastronomy - Physical and Chemical Aspects of Flavour Pairing (strongly recommended)
- Advanced Biochemical Analysis of Foods - Product Composition
- Advanced Biochemical Analysis of Foods - Product Authenticity and Toxicology
- Food Ingredient Functionality
After completion of two or more courses there is a unique opportunity to apply what you have learned. You can start a capstone project in consultation with a Wageningen expert in the field. It is a tailor-made project, where you will write a short paper about your results and conclusions. During this work you will be coached by the expert. Price: €1,230,-.
Level of knowledge
The language of instruction of this course is in English. Admission to the course requires a level of English as defined at the website for Dutch nationals, EU nationals or nationals outside EU/EFTA respectively.
You can complete the course(s) with an exam (not obligatory) or a capstone project. When completed successfully this will be mentioned on your certificate (included in the price).
