Valorization of Side-Streams
Background
The increasing global demand for food leads to a concomitant growth of food industry by-products. From an economical and environmental perspective, the need for efficient side-stream management is crucial for a circular food value chain and the valorization of underutilized biomass. Within the wide variety of food products, vegetable-based side-streams provide a versatile source of renewable biomaterials with peculiar properties. Recognizing food production side-streams as valuable raw-materials is the first step towards a sustainable use of resources and the conversion of agri-food residues into higher added value products. Since the crops are intended for food production and human consumption, the on-filed residues are biomaterial of food grade quality. This provides the unique opportunity to reintroduce plant-derived products into the food value chain and the use in food applications.

Research Goals
The overall objective of this project is to valorize the functional ingredients, in particular the water-soluble polysaccharides, of plant-based side-streams. Broccoli stems serve as a model crops to improve extraction and purification of the soluble dietary fibers from the natural resources and conduct their full characterization. In addition, the project focusses on the modification of their physiochemical properties in order to make them applicable for use in food products.
