Antibacterial effect of chitosan in relation to active food packaging
Høie, Miriam (Masteroppgave/UIS-TN-IMN/2017;, Master thesis, 2017-06)Food safety has a high priority in the food industry. In order to be able to give the consumers safe products, the producers continuously work with methods to inhibit growth of bacteria in the foods during storage. Recently, ... -
Combined Effect of Citric Acid and Polyphenol-Rich Grape Seed Extract towards Bioactive Smart Food Packaging Systems
Pažarauskaitė, Akvilė; Noriega Fernández, Estefanía; Sone, Izumi; Sivertsvik, Morten; Sharmin, Nusrat (Peer reviewed; Journal article, 2023-07)Alginate films (2% w·v−1) were prepared with varying concentrations (5–20% w/w) of citric acid and aqueous grape seed extract (GSE) filtrate (11.66 ± 1.32 g GAE/L) using the solvent-evaporation method. Crosslinking alginate ... -

Dietary behavior of home-living older adults: the role of environmental factors
Kvalsvik, Fifi Tjan (PhD thesis UiS;, Doctoral thesis, 2022-10)While many home-living older adults seem to consume a nutritionally adequate diet, the prevalence of malnutrition in older people living at home remains high and frequently overlooked. Malnutrition in older adults has been ... -
Mechanical, barrier, antioxidant and antimicrobial properties of alginate films: Effect of seaweed powder and plasma-activated water
Dysjaland, Hege; Sone, Izumi; Noriega Fernández, Estefanía; Sivertsvik, Morten; Sharmin, Nusrat (Peer reviewed; Journal article, 2022)The incorporation of natural fillers such as seaweed may potentially enhance the properties of biopolymer films. In this study, we investigated the effect of seaweed powder as a bio-filler in alginate-based films at different ... -
Seaweed-based Films for Potential Food Packaging Applications
Dysjaland, Hege (Master thesis, 2022)The focus on environmental issues and the challenges related to traditional plastic materials has triggered the use of bio-based packaging materials. Alginate is a natural biopolymer with good film-forming properties. In ... -
Technology-Enabled Smart Biomaterials for Food Packaging Systems and Edible Coating
Pazarauskaite, Akvile (Master thesis, 2022)The rising awareness on the environmental impact of conventional plastics and the rapid pace of food innovation have shifted the interest towards biodegradable, smart food packaging materials using biopolymers (e.g. alginate) ...
