1. Sustainable food packaging based on polyhydroxyalkanoate
Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomiSammanfattning : The Norwegian Food Research Institute (Nofima) and the University of Borås worked together to develop this project. The commonly used packaging materials pose a serious threat to the environment, as they are produced from nonrenewable crude oil and cannot decompose naturally. LÄS MER
2. Kaolin-based coating colors with different rheological and water retention properties : Runnability on a lab-and pilot scale
Master-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)Sammanfattning : Food packaging plays a crucial role in protecting and storing food to keep the products fresh and reduce waste. There is a need to increase the number of paper packages in the food industry to meet the growing demand. LÄS MER
3. Formulation and characterisation of novel edible-packaging for fruits and vegetables
Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)Sammanfattning : This master's thesis investigated the potential of algae raw materials, specifically k-carrageenan and to a lesser extent alginate, as film-forming ingredients for the development of a novel edible packaging solutions. The project involved the testing and characterisation of several active ingredients of algal and plant origins both as extracts and as ingredients in films. LÄS MER
4. Varnishing of Fiber-based Closures
Master-uppsats, Lunds universitet/FörpackningslogistikSammanfattning : This research aims to investigate water-based varnishes and technologies to coat fiber-based closures to attain water barrier properties. To ensure recyclability the repulpability of coated and uncoated lids is tested. The research approach is exploratory. LÄS MER
5. 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)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
