  1. 6. 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.

  3. 7. 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

  4. 8. 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.

  5. 9. Pulsed electric field treatment of wheat bran to improve arabinoxylan extraction

    University essay from SLU/Department of Molecular Sciences

    Author : Agnes Wahlsten; [2021]
    Keywords : Arabinoxylan; wheat bran; pulsed electric field technology; alkaline extraction;

    Abstract : Valorization of agricultural and industrial by-products reduces the environmental impact of food production. Innovative low impact processes for food processing further limit the contribution and additionally enhances the generation of novel health-promoting foods. READ MORE

  6. 10. A comparative study of Product Environmental Footprint (PEF) and EN 15804 in the construction sector concentrating on the End-of-Life stage and reducing subjectivity in the formulas

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Seyed Shahabaldin Seyed Salehi; [2020]
