  1. 1. Machine Concept for Pulsed Electric Field Treatment of Leafy Products

    University essay from Lunds universitet/Produktutveckling

    Author : Patrik Johansson; [2022]
    Keywords : Product development; Opticept; PEF; Leafy Products; Prototyping; Technology and Engineering;

    Abstract : This master thesis, executed in collaboration with Opticept Technologies, has the purpose of developing a machine concept that enables the treatment of leafy products with Pulsed Electric Fields (PEF). PEF is an emerging technology within the food industry that works by changing the cell membrane structure of food products by exposing them to high-voltage electric fields. READ MORE

  2. 2. Bioplastics Material Flow Analysis And Their Environmental Impacts

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

  3. 3. Integration of food shelf-life in life cycle assessment of polymers

    University essay from Lunds universitet/Förpackningslogistik

    Author : Divya Sukumaran Nair; [2021]
    Keywords : Food shelf-life; life cycle assessment; biopolymers; food packaging; sustainability; shelf-life induced food waste; Technology and Engineering;

    Abstract : Biopolymers are being considered as a promising alternative to fossil-based polymers and this inclination towards biopolymers is due to their lower environmental impact owing to their origin from renewable resources. The environmental impact assessment, however, often does not consider the impact of barrier properties of polymers and the resulting differences in food waste generated in the supply chain.

  4. 4. The effectivity of vacuum impregnation with glycerol and secondary metabolites on electroporated arugula leaves to improve freezing stability.

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Oscar de Kuijer; [2021]
    Keywords : Pulsed electric field PEF; Arugula; Electroporation; Secondary metabolites; Glycerol; Food engineering; Livsmedelsteknik; Technology and Engineering; Agriculture and Food Sciences;

    Abstract : Freeze damage is a common issue in many food items. The cellular dehydration caused by freezing can be prevented through addition of a cryoprotectant. Research has shown that it is possible to improve the freezing tolerance of plant materials by addition of cryoprotectants, which forms hydrogen bonds with water molecules. READ MORE

  5. 5. Effects of Vacuum Impregnation with Various Substances in Combination with Pulsed Electric Field to Improve the Freezing Tolerance of Arugula Leaves

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : George Lukhava; [2021]
    Keywords : Food Engineering; Food Preservation; Pulsed Electric Fields; PEF; Vacuum Impregnation; VI; Arugula; Cryoptrotectant; Glycerol; Secondary Metabolites; Folic Acid; Folate; Folacin; Vitamin B1; Thiamine; Thiamin; Agriculture and Food Sciences;

    Abstract : As of 2020 an estimated number of 821 million people across the world are undernourished and that figure is expected to grow by 2 billion before the end of 2050 (United Nations Sustainable Development 2020). Despite this, every year over 1/3 of food produced globally is disposed of without consumption (Global Panel on Agriculture and Food Systems for Nutrition 2018), and the actual number might be much higher.
