  1. 1. Prolongation of shelf life of minimally processed spinach by combining vacuum impregnation and electric field treatments

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

    Author : Sophia Leffler; [2022]
    Keywords : spinach; pulsed electric field; moderate electric field; reversible electroporation; vacuum impregnation; shelf life; metabolic activity; respiration; food engineering; Agriculture and Food Sciences;

    Abstract : A continuous growth of the world population raises the importance of preserving food resources while maintaining their nutrient value. Leafy vegetables such as spinach are a food category which decay quickly, and a large amount ends up as food waste. READ MORE

  2. 2. 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

  3. 3. 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.

  4. 4. Engineering Rhodosporidium toruloides for the production of polyhydroxybutyrate

    University essay from Lunds universitet/Teknisk mikrobiologi

    Author : Tova Lindh; [2021]
    Keywords : Applied microbiology; Bioplastics; Rhodosporidium toruloides; Polyhydroxybutyrate; Non-conventional yeast; Oleaginous yeast; Biology and Life Sciences;

    Abstract : The increased use of plastics has become an environmental problem where plastics, due to the slow degradation, accumulate in the oceans and landfills. Although plastics are a very cheap and useful material with desirable properties and a wide variety of applications, they are primarily made from petroleum-based resources which are non-renewable and of fossil origin.

  5. 5. Pulse Electric Field as a Pre-treatment Method of Wastewater Sludge prior to Anaerobic Digestion

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Milton Matilde; [2020]
    Keywords : PEF; AD; biogas yield; sludge pre-treatment; water engineering; environmental engineering; avloppsteknik; vattenförsörjningsteknik; Technology and Engineering;

    Abstract : This work analyzed the impact caused by different intensities of Pulsed Electric Fields (PEF) pre-treatment on the biogas production from small-scale anaerobic digesters of wastewater sludge under thermophilic conditions. PEF technology consists of passing the substrate through an electric field which generates a potential difference across the cells, resulting in electroporation. READ MORE
