Description:

Project description: Fat functionality in foods The objective of the PhD project is to understand the functionality of fat and fat replacers in foods and beverages. The influence of fat droplet properties on the sensory perception of liquid emulsions is investigated. The effect of the interactions between oil droplets and thickening agents on the formation of oral coatings and the subsequent influence on sensory perception is studied. Emulsion filled gels and double emulsions are used as model systems. The effect of particle size and fat composition on the rheological, tribological and sensory properties are investigated. With regard to double emulsions, the influence of amount/size of water droplets contained in the fat droplets, the effect of surfactants/stabilizers and thickeners on the structure, stability and sensory perception is studied. In addition, the PhD project aims at elucidating the relationship between the molecular properties of fat replacers (morphology, size, surface properties, functional properties) and their fat mimicking functionalities. The effect of selected fat replacers is studied in liquid and semi-solid foods. Main tasks and responsibilities The PhD student is responsible for: developing, planning and performing of specific research tasks within the project “Dynamics of texture and taste perception”. contributing to the full project plan staying abreast of developments in his scientific discipline by keeping up with the scientific literature in his field and visiting scientific meetings generating ideas within the scope of the defined subject supervising of research assistants and students, where appropriate delivering results in line with the project plan milestones and deliverables keeping up with the latest scientific developments and integrating these in the project converting data and results of the sub-project into overview reports keeping  traceable records of all results and analyses according to the lab journal procedure writing high-quality clearly written papers about the results obtained and getting these published in high–impact scientific journals. completing a thesis after 4 years.
