Summary

The possibilities for better usage of agricultural by-products are discussed in the thesis entitled “Biomass
and its potential for protein and amino acids; valorizing agricultural byproducts”. In this thesis, several
agricultural by-products were tested that are currently used as low value animal feed or as waste for
their potential as a resource for protein and/or amino acids. With new developments on biomass pretreatment
and protein extraction methods, more valuable protein will be available. Next to protein
extraction, additional steps involving enzymes at mild acidic conditions can breakdown the protein into
amino acids. A method to obtain glutamic acid from gluten was developed. Glutamic acid can be used in
food as a flavor enhancer, but also to produce bio-based products that substitute petrochemical-based
products. These new insights can be used for more efficient use of raw materials to avoid protein
shortage and indirectly aid the environment.
