Wanted: Alternative Protein Sources for Humans

Alternative plant-protein sources are on trend. In the ‘HumanProt Sources’ research project, our researchers test a key quality criterion of these proteins – their digestibility – in the laboratory. In addition, they compare the quality of Swiss plant and animal protein sources.

This scientific group is first specialized in the analysis of milk, dairy products and foodstuffs transforming micro-organisms. The group is divided into three laboratories:

  • Biochemistry of milk and dairy products
  • Metabolites & proteins
  • Bacterial metabolism

This scientific group offers a qualified platform for the analysis of proteins and metabolites using qualitative and quantitative methods.

The strong points of its activities are:

  • processes and physiological and biochemical effects during the consumption of dairy products on human health
  • microbial metabolism in lactic acid and propionic acid bacteria (e.g. production of flavours and amines)
  • the characterization of all proteins and metabolites in milk and lactic acid bacteria (proteomics und metabolomics)
  • processes of maturation of cheeses (e.g. determination of lactic acid, amino-acids and enzymatic activities)
  • the support to the national reference laboratory for the quality of raw milk (determination of the cell number and detection of inhibiting substances)
