The main research focus is on understanding the effect of processing on physical, chemical and structural characteristics of foods, and uses this knowledge to develop new processes and products. I have worked with a large number of food matrixes and processes under study include both traditional and novel technologies.

 

Primary fields of research

• Mild sustainable process technologies
• Technologies to produce dairy powders and concentrates
• Structure processing

Current research

On going projects:

• Platform for Platform for Novel Gentle Processing - (Mejerirationaliseringsfonden, Arla Foods and Copenhagen University) (2016-2022)

• Novel Aging – Technologies and solutions to manufacture novel dairy products for healthy aging funded by Innovation Fund Denmark / DDRF SuperCalcium (2017-2021)

• P project – Personalised food Products for Patients (3D printing) – Innovation Fund Denmark – (2018- 2021)

• ProOrg – ERA net Core Organic on Organic Processing - (2017- 2021)

• Effectiv drying and reconstitition of powder yogurt  (MFF/ GEA) (2018-2022)

• Gelcook - Elucidating the mechanism of formation of cookable milk gels - DDRF/Arla Foods (2020-2023)

• Procalcium -  Calcium dynamics during manufacturing of cheese - DDRF/Arla Foods (2021-2024)

• Structuring dairy proteins (Marie Skłodowska-Curie grant) (2021-2024) 

• Collaboration in Dairy Process Technology between the University of Copenhagen in Denmark and National Dairy Research Institute in India, funded by Novozymes A/S & The Henning Holck-Larsen Fond – 1 Postdoc (2017)
