    Shaping a Data Commoning Polity: Prospects and Challenges of a European Digital Sovereignty

    No full text
    The concept of “digital sovereignty” has gained momentum due to the emergence of a multipolar geopolitical scenario based upon different visions of today’s digital society. In this scenario, the United States, China, and the European Union are major players, each pursuing their understanding of digital sovereignty and their approach to digital transformation. The EU conceives of digital sovereignty as technological autonomy from other competitors, and to achieve this it has carved for itself the role of international regulator. De facto, however, the EU enacts an individual-centric and economic-driven digital strategy that hinders the possibility of a fully-fledged European digital sovereignty. Notably, the concept fails to embed the collective-level dimension proper to sovereignty as such. To tackle this, the paper explores data commoning as the basis for shaping a well-formed European polity, key to its digital sovereignty.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Urban Data Scienc

    Production and enrichment of bioactive peptides derived from milk proteins

    No full text
    In this chapter, information is given on the production of bioactive peptides from milk proteins. After defining bioactive peptides, the necessity to release bioactive peptides from the parent protein is discussed. Then, the two main approaches for release, namely enzymatic hydrolysis and microbial fermentation are reviewed. Next, an overview is given of the main unit operations that can be applied for the enrichment and selective isolation of bioactive peptides from the protein hydrolysates, including membrane filtration, chromatography and precipitation. Attention is given mainly to ACE-inhibitory peptides, and to processes that show potential for application in the dairy industry
