PhD in Natural Variation in Goat Milk Caseins

Location Wageningen

We are looking for

Do you want to use your passion for food science to carry out research on milk from individual goats? Are you willing to help our researchers to find answers to better understand natural variation in the composition of goat milk caseins and its influence on goat milk properties? Then this PhD vacancy in the Dairy Science and Technology team of the Food Quality and Design group may be interesting for you.

The main Dutch dairy goat breeds are Saanen and Toggenburger, which originate from Switzerland and are used for their high milk yields. Considering the popularity of goat milk products, surprisingly little is known about the casein fraction of goat milk and its functionality compared to what we know of bovine milk. This knowledge is essential to understand the functionalities of dairy products made from goat milk, such as heat stability of UHT milk or renneting behavior of cheese milk. Therefore, the main aim of the project is to determine variation in goat milk casein composition and casein micelle structure of the Dutch goat breeds and the effect of this variation on selected functionalities.  

Your main tasks will be:

  • Designing and executing experiments to determine variation in casein composition, casein post-translational modifications and casein micelle structure in milk obtained from individual goats, using various analytical techniques such as HPLC, LC/MS based proteomics, light scattering and microscopic techniques;
  • designing and executing experiments to understand functionality of goat milk in relation to, for example, heat aggregation of proteins and UHT-milk shelf-life stability;
  • performing in-depth analyses of results and writing of high quality scientific papers.
This PhD project is supported by an industrial dairy partner. The goat milk farmers that are associated with this partner, are providing milk that is processed into a variety of products such as goat milk cheese, UHT milk and infant formula. You will cooperate with these parties to achieve the project objectives and obtain relevant input on your project. Furthermore, you are expected to effectively communicate with project stakeholders and present your results to the wider scientific community.

You are expected to complete a PhD dissertation within four years.
