1. 16. Mechanistic Model Development for a Multi-Enzyme Protein Hydrolysis Process

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

   Författare :Tito Nilsson; [2023]
   Nyckelord :Mechanistic Model; Enzyme; Hydrolysis; Chemical Engineering; Technology and Engineering;

   Sammanfattning : New food products are constantly put on the market. Today the focus often lies in creating nutritional and sustainable products to reduce the environmental impact of the product in question. One example of this is the approval of the yellow mealworm, Tenebrio Molitor, as a novel food in the European union. LÄS MER

3. 17. Investigation of Milled Wood Lignin Extraction Using Enzymatic Hydrolysis for Application in Hydrophobic Barriers in the Food Packaging Industry

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

   Författare :Anna Wagne; [2023]
   Nyckelord :Lignin; extraction; hydrophobicity; chemical engineering; Technology and Engineering;

   Sammanfattning : The objective of this report is twofold: to optimise the extraction method of lignin from spruce altering a few process parameters and to investigate the use of lignin as a hydrophobic barrier in food applications. The process used was STEX (steam explosion) pretreatment followed by enzymatic hydrolysis and MWL (milled wood lignin) extraction using a mixture of dioxane-water. LÄS MER

4. 18. Reprocessing and Characterization of Polybenzimidazole for High-Temperature Polymer Electrolyte Membrane Fuel Cells

   Master-uppsats, Lunds universitet/Centrum för analys och syntes

   Författare :Douglas Björkengren; [2023]
   Nyckelord :polymer electrolyte membrane fuel cells; PEMFC; HTPEMFC; polymer technology; polymer characterization; reprocessing; recycling; polybenzimidazole; PBI; Technology and Engineering;

   Sammanfattning : A reprocessing method of poly(2,2’-(m-phenylene)-5,5’-bibenzimidazole) (PBI) membranes recovered from the production line of High-Temperature Polymer Electrolyte Membrane Fuel Cells (HT-PEMFC) at Blue World Technologies (BWT) has been developed in order to reduce material loss in the production. Redissolution of scrap PBI membranes in poly(phosphoric acid) (PPA) and phosphoric acid (PA) was successful and the subsequent washing procedure produced PBI that could be redissolved in N,N-dimethyl acetamide (DMAc) and suitable for solution casting of new membranes.

5. 19. The Development and Testing of Low-Cost Heat Transfer Enhancements for Solar Dryers

   Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

   Författare :Hoda Mahmoodi; [2023]
   Nyckelord :Solar dryer; Bhutan; Drying rate; Solar absorber; Technology and Engineering;

   Sammanfattning : In the mountainous regions of Bhutan and Nepal, post-harvest losses cause significant challenges for producers. Open air sun drying is usually used by farmers to preserve their produce. There are many disadvantages to this method. LÄS MER

7. 20. Investigation of the impact of different sugar compositions on the moisture absorption of hard candy when exposed to a humid environment

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

   Författare :Gila van den Eijnde; [2023]
   Nyckelord :Hard candy; Sugar composition; Hygroscopicity; Moisture absorption; Shelf life; Product stability; Food technology; Technology and Engineering;

   Sammanfattning : Hard candy is hygroscopic, implying that hard candy readily absorbs moisture from the environment, resulting in adverse changes in the texture and appearance of the candy. This thesis investigates the impact of different sugar compositions on the moisture absorption of hard candy when exposed to a humid environment. LÄS MER
