  3. 2. Formulation and characterisation of novel edible-packaging for fruits and vegetables

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

    Författare :Lola Sutton; Katerina Papa; [2023]
    Nyckelord :algae; edible packaging; carrageenan; cucumber; REL; oxidative stress; antioxidants; food engineering; Technology and Engineering;

    Sammanfattning : This master's thesis investigated the potential of algae raw materials, specifically k-carrageenan and to a lesser extent alginate, as film-forming ingredients for the development of a novel edible packaging solutions. The project involved the testing and characterisation of several active ingredients of algal and plant origins both as extracts and as ingredients in films. LÄS MER
