11. Pulse Electric Field as a Pre-treatment Method of Wastewater Sludge prior to Anaerobic Digestion
University essay from Lunds universitet/Kemiteknik (CI)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

12. Upscaling of FDCA Synthesis from HMF to an Industrial Scale
University essay from Lunds universitet/Kemiteknik (CI)Abstract : To support the transition into green plastics, the upscaling and economic analysis of 2,5-furandicarboxylic acid (FDCA) synthesis from 5-hydroxymethylfurfural (HMF) was done. The project can be described as a plant-to-plastics process, with sugar beet-derived HMF as a starting point. READ MORE

13. Shelf life of fresh-cut fruits and salad leaves treated with Pulsed Electric Field (PEF)
University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)Abstract : Application of Pulsed Electric Field (PEF) treatment on five fresh commodities was analysed for the changes in the metabolic and physiological effects on their shelf life. Treatment parameters were optimised in order to achieve uniform electroporation on the samples, which was analysed by Propidium Iodide staining for the leaf samples. READ MORE

14. Optimization of Pulse Electric Field Treatment and Vacuum Impregnation for Reducing Freezing Injury of Thawed Rucola Leaves
University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)Abstract : Freezing injuries usually take place in thawed plant-based food products. To reduce freezing injuries, Pulse Electric Field (PEF) treatment and Vacuum Impregnation (VI) of cryoprotectant were used before the freezing process. READ MORE

15. Application of pulsed electric fields and vacuum impregnation to improve the freezing tolerance of fresh Origanum vulgare leaves
University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)Abstract : One of most ancient food preservation methods is freezing because there are not caused significant changes the sensory characteristics and nutritional value of foods. Last decade, have been made great steps for the optimization of freezing tolerance of fresh vegetables, fruits and species. READ MORE
