Food and Feed Biochemistry

 Food and feed biochemistry, including characterization, quality assessment, and metabolic fate of food components, is central for much of our research. Current research projects (initials of relevant scientists in brackets) include studies of allergenic food proteins (HF), influence of various food components on the immune system (HF, SM), influence of neutral and phosphorylated monosaccharides in pork on aroma volatiles during cooking (CB), chemical transformations in vegetables before and after ingestion (JCS, NA), and insects as models of mammalian phase 2 metabolism of dietary phenols (NA), and tests of products of new bioprocessing technologies (KEA, JCS).
