PhD fellowship in applying electrodialysis to acid
Department of Food Science (FOOD), Faculty of Science at University of Copenhagen is offering a PhD fellowship in applying electrodialysis to acid whey from 1 September 2019 or soon thereafter.
The Department of Food Science, Faculty of Science at the University of Copenhagen seeks a PhD candidate to work on a PhD project regarding application of electrodialysis to acid whey. This PhD project is part of the Platform for Novel Gentle Processing and Shelf-life Intelligence that is a dynamic industrial multidisciplinary environment supported by Danish Dairy Research Foundation.
Electrodialysis (ED) is a membrane separation process for charged molecules via ion exchange membranes. Charged components are transported from one solution to another due to the influence of applied electrical potential. Acid whey is a by-product of strained yoghurt, cream cheese and chemical acidification of milk in dairy production. Previous studies have proven the high effectiveness of ED for demineralization of whey and removal of lactic acid from fermentation broths and acid whey to improve down-stream processability, e.g. reduce stickiness of whey powder during spray-drying. However, there are still a number of challenges regarding application of ED to acid whey. The complexity of the feed, criteria for selection of the membranes and reduction of fouling require basic understanding and knowledge to make ED process more effective and robust.
The objective of this work is to improve the basic understanding of ED regarding separation of lactic acid and/or demineralisation of acid whey.
