  1. 1. In-plane Wetting in Packaging Material and its Consequences for Cap Performance

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Ellinor Carolina Salomonsson; [2023]
    Nyckelord :Tetra Pak®; Aseptic; Paperboard; Pre-laminated hole; Edge wicking; In-plane wetting; Hydrogen peroxide; Cap detachment; Polymer technology; Technology and Engineering;

    Sammanfattning : Aseptic packaging solutions enable long time storage without refrigeration and are an important part of securing food supply globally. The package material consists of multiple layers: A paperboard for robustness, polymers for adhesion as well as shielding the board from liquid, and a barrier protecting the product. LÄS MER

  4. 3. A plant-based milk powder that functions as a substitution for regular milk powder

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Manon Scheffers; [2023]
    Nyckelord :spray drying; pant- based milk powder alternative; pea protein; food application; food engineering; Technology and Engineering;

    Sammanfattning : This project tested the potential of plant based milk powders to function as an animal-based milk powder by testing them on multiple characteristics. The powders were produced using spray drying techniques, obtained using formulations differentiating in protein amount, ratio of maltodextrin:sucrose and two different protein sources. LÄS MER

  5. 4. The Influence of Pigment Additives on the Barrier Properties of Dispersion Coatings

    Master-uppsats, KTH/Fiber- och polymerteknologi
