1. Enhancing the stability of probiotics: Freeze-drying and encapsulation
Sammanfattning : This research dives into the intricate world of freeze-drying, an essential process in pharmaceutical and probiotic industries, to better understand the factors affecting probiotic stability during storage. The process of freeze-drying and the composition of freeze-dried products significantly affect the stability of probiotics, yet factors such as the material’s encapsulation properties remain relatively unexplored, demanding further research.

2. Impact of Cultivation Parameters on Cell Physiology of Limosilactobacillus reuteri
Sammanfattning : Optimisation of cultivation conditions in the industrial production of probiotics is crucial to reach a high-quality product with high probiotic functionality. The production process includes a fermentation step to produce biomass, accompanied by centrifugation to concentrate the cells. LÄS MER
3. Absorbent Materials from Kraft Pulp
Sammanfattning : SuperAbsorbent Polymers (SAPs) have, since being introduced in the 1980s, become an important constituent in hygiene products, such as disposable diapers. The design of disposable diapers has changed over the years and today thinner products can be produced partly because of the excellent absorption and retention properties of the petrochemical-based SAPs.

4. Gluten Protein-Based Microcellular Foams and Composites: Development and Functional Properties
Sammanfattning : Most common foams are produced from non-renewable resources (e.g., synthetic plastics),with a number of environmental concerns, hence there is a demand for alternative bio-derivedfoam materials. Wheat gluten protein is widely known to have excellent foaming properties(e. LÄS MER
5. Development and Evaluation of Preparation Methods for the Analysis of Cell Membranes Using Time-of-Flight Secondary Ion Mass Spectrometry
Sammanfattning : The aim of this work was to evaluate and develop methods for preparing dry samples for TOF-SIMS analysis of cell membranes. For correct interpretation of the analysis data, an understanding of the effects that the preparation method has on the morphology and chemical structure of the sample must first be obtained. LÄS MER
