Emulsions in food - Product and process development
If you work with product development, improving durability and ensuring quality of food such as salad dressings, chocolate spread, mayonnaise, and sauces (e.g. bearnaise) which are considered emulsions, then this is the course for you.
Learn about emulsifying fats in water and water in fats and identifying suitable natural and / or synthetic emulsifiers.
Danish Technological Institute now offers this easily accessible course in food emulsions. These products require natural or synthetic emulsifiers to prevent phase separation and to ensure durability of the emulsified food which is of great importance for consumer perception of many products. The course reviews the theory behind an emulsion, methods for preparing and characterizing an emulsion and crucial parameters for obtaining good product quality.
Yield
- Basic understanding of emulsions in foods
- Knowledge of preparation and characterization of emulsions
- Understanding of factors that affect the shelf life of emulsified foods
- Knowledge of interpretation of results from particle size analysis, particle charge and viscosity of emulsions
- Practical experience in making and characterizing emulsions in the laboratory
Participant profile
People who carry out product development of food such as salad dressings, chocolate spread, mayonnaise, and sauces (e.g. bearnaise) which are considered emulsions, where the shelf life of emulsified foods is a quality parameter.
Teacher
Bianca C. Pérez de Lucani, Senior Specialist, Ph.D. in the Center for Food Technology. Bianca Pérez has hands-on experience in emulsifying foods and characterizing emulsions.
