In this paper, we review the physicochemical phenomena occurring during the structuring processes in the manufacturing of plant-based meat analogs via high-moisture-extrusion (HME). After the initial discussion on the input materials, we discuss the hypotheses behind the physics of the functional tasks that can be defined for HME. For these hypothe...
Plast ger otroliga möjligheter i form av stor variation för materialanvändning. Tyvärr sker det dock på bekostnad av miljön då de ackumuleras i naturen. En kompromiss mellan hållbarhet och fortsatt plastanvändning skulle kunna vara att använda biomassa som fyllnadsmaterial i plastkompositer istället för plast. Detta skulle i sin tur minska mängden ...
A two-factorial central composite design was performed to investigate the effects of preconditioning water content (PCwater: 21, 22.5, 26, 29.5 or 31%) and die temperature (Dtemp: 115, 119.4, 130, 140.6 or 145 ℃) on the physical properties of extruded floating fish feed. This design was applied to two separate diet formulas to study the effect of c...

To quantify dentoskeletal changes accompanying the use of extrusion arches during the treatment of anterior open bite (AOB) in adults. A total of 23 adult patients with an AOB of -3.05 mm ± 1.27 mm were treated with upper and lower extrusion arches after the alignment phase. Lateral cephalograms were taken before placement of the extrusion arch, im...
In the present study, alginate-pectin (Al–P) hydrogel particles containing varied total gum concentrations (TGC) at a constant Al:P ratio of 80:20 were formed utilizing an innovative extrusion-based 3D food printing (3DFOODP) approach. The 3DFOODP conditions, namely, TGC (1.8, 2.0, and 2.2 wt%) and nozzle size (0.108, 0.159, and 0.210 mm) were inve...
V práci je zkoumán vliv obsahu stabilizačního aditiva v extrudovaném multifilamentním vlákně a jeho degradace při osvitu slunečním zářením. Cílem práce je optimalizace – snížení nebo zvýšení – objemového poměru aditiva v produktu pro snížení ceny vstupních nákladů. Multifilamentní vlákno je vystaveno ultrafialovému záření v komoře pro akcelerované ...
High moisture extrusion (HME) is a common method to produce meat analogues. This process requires cooling of the product in the die and is associated with a high mechanical energy input. Here, we use high-temperature shear cell (HTSC) technology to better understand the importance of cooling while shearing for the formation of fibrous products upon...
In this thesis a range of catalyst pellets are studied using Nuclear Magnetic Resonance (NMR) and Magnetic Resonance Imaging (MRI) techniques with the aim of characterizing mass transport in the pellets and exploring the presence of spatial heterogeneities formed in the manufacturing process. Measurements have been done both in bulk, i.e. spatially...

Wide aluminium panels with stiffeners are extensively applied in aviation, bridge and marine structures due to their high stiffness and light-weighting. Many efforts and contributions have been made to overcome the manufacturing difficulties of wide aluminium stiffened panels over years. The aim of this study is to analyse and compare current metho...
