Project Leader Maud Langton

Expertise in: Characterization of the food raw material, food products as well as bio-based food material by different physico-chemical and structural methods from nano to macro levels. The overall objective is to design structures with targeted properties, to be applied in food or/and bio-based materials.

Brief summary of the major achievements in C4F

· Related to C4F we have three PhD-students; Anja Herneke, she is working on protein extraction and nano-fibrillation, Klara Nilsson characterizing the polysaccharides from faba beans, and Solja Pietiäinen working on the fractionation and characterization of wheat bran (financed by Strategiska Stiftelsen and Lantmännen).  

· The team has extracted protein from faba beans, mung beans and lupins.

· Nano fibrils has been produced from the extracted faba bean, mung beans and lupin proteins.

· Nano fibrils have been characterized. The results are not consistent, thus a delay in publication.

· Work in collaboration with KTH on nano fibril from whey protein has moved forward and two publication and one book chapter has been published.

· During 2017 two post-doc were employed on other funding working very close to TC4F, Daniel Johansson working on protein nano-fibrils and Jing Li working on complex materials, Iron nano-particles attached to the protein nano-fibrils.
