Evaluating 3d Printing As A Technology For Producing Dairy Snacks Based On Temperature-Controlled Rennet Induced Gelation Of Protein-Fortified Milk., Ricardo Uribe Alvarez
ORBioM (Open Research BioSciences Meeting)
3D food printing (3DFP) has the potential to develop products with complex structures, personalised nutrition, and customised textures. However, only foods with suitable physicochemical or rheological properties are suitable for 3DFP to ensure a self-supported structure is printed. Milk proteins can form structured objects (i.e., cheese, yoghurt), and so are potential ingredients for 3DFP. This study aims to adapt the rennet gelation from the curdling process of cheese-making to produce 3D printed dairy snacks using milk protein isolate-fortified milk. It is well known that curdling of milk by rennet is temperature dependant; therefore, the rennet gelation properties (G' and G'') …

Listeria Monocytogenes'. A Genomic Perspective On Its Pathogenesis, Persistence And Bacteriophages., Aidan Casey
Theses
The objective of this study was to investigate the genetic characteristics of Listeria monocytogenes that contribute to the threat it poses to the food processing industry. Transcriptomic analysis of a persistent L. monocytogenes isolate following exposure to an industrial detergent identified key upregulations in biological processes involved m peptidoglycan biosynthesis, chemotaxis and motility. Two bacteriophages against serotype 4b and 4e isolates of L. monocytogenes were isolated and sequenced. Comparative genomic and functional analysis identified the receptor binding proteins in each phage, whi]e transmission electron microscopy demonstrated a conserved baseplate architecture which also exists in other Grampositive phages. Comparative genomics of …

System Identification Of A Pasteurisation Process: A Comparison Of Direct And Indirect Methods, Niel Canty
Theses
The primary focus of this research is to identify a linear model for a direct steam injection (DSI) pasteurisation process which is a component of a large-scale pilot evaporation process widely used in the dairy industry. The pasteurisation process has been identified as a key component of the evaporation process. The author believes that no previously published work has focused on identifying models for a DSI pasteurisation process which makes this work an original contribution to the area. The pasteurisation process can be modelled as a single-input, single-output (SISO) process with a measurable disturbance. Thus two transfer functions were required …
