Development Of Novel Pectinase And Xylanase Juice Clarification Enzymes Via A Combined Biorefinery And Immobilization Approach, Shady Hassan
Development Of Novel Pectinase And Xylanase Juice Clarification Enzymes Via A Combined Biorefinery And Immobilization Approach, Shady Hassan
Doctoral
Hydrolytic enzymes, such as pectinase and xylanase, maybe harnessed for numerous industrial applications in food industry. Therefore, economic factors such as achievement of optimum yieldsandoverall production costs, in addition to biocatalyst instability,are the main obstacles tothe industrial production and exploitation of a enzymes. For example, microbially-derived enzymes are typically produced in fermenters using expensive growth media, which may account for 30 to 40% of the production cost, and such expense may be compounded further by downstream processing operations.To counter such disadvantages, the major trend in industrial utilization of enzymes in cost-sensitive processes has been to immobilize such biocatalysts on a …
Chemical Effects Of Cold Atmospheric Plasma On Food Nutrients, Juan Manuel Pérez Andrés
Chemical Effects Of Cold Atmospheric Plasma On Food Nutrients, Juan Manuel Pérez Andrés
Doctoral
A range of nonthermal techniques have demonstrated process efficacy in ensuring food product safety, extension of shelf-life and in general a retention of key quality attributes. However, various physical, chemical and biochemical effects of nonthermal techniques on both macro and micronutrients are evident, leading to both desirable and undesirable changes in food products. It is important to outline the effects of non-thermal techniques on food chemistry and the associated degradation mechanisms with the treatment of foods. Oxidation is one of the key mechanisms responsible for undesirable effects induced by non-thermal techniques. Degradation of key macromolecules largely depends on the processing …
Recognising The Place Of Food Tourism In Ireland: An Autoethnographic Perspective, John D. Mulcahy
Recognising The Place Of Food Tourism In Ireland: An Autoethnographic Perspective, John D. Mulcahy
Doctoral
This is an autoethnographic account, utilising prior publications, of my role in positioning food as a critical ingredient in Ireland’s tourism policy and strategy since 2009. As the architect and instigator of this project, my priorities were threefold: first, working from the ground up identifying local activists across the food tourism landscape to create an active and vibrant network; second, providing thought leadership for food tourism; and third, encouraging and funding others to conduct and disseminate similar research. I have chosen six book chapters, published as a result of my advocacy strategy, for this PhD by prior publication. They are …
Plasma Functionalised Liquids: From Bench To Prototype For Safe Fresh Food Preservation, Uta Schnabel
Plasma Functionalised Liquids: From Bench To Prototype For Safe Fresh Food Preservation, Uta Schnabel
Doctoral
Fresh-cut produce such as lettuce may contain a very high microbial load, including human pathogens. Therefore, the need for antimicrobial interventions at post-harvest stages to prevent microbial growth is evident. Sanitation steps based on non-thermal plasmas at atmospheric pressure opens up innovative food processing possibilities by application at different points along the food chain; for production, modification and preservation, as well as in package treatment of plant- and animal-based foods. Plasma differs from the gaseous state of matter by a certain amount of free charge carriers caused by ionisation processes of the gas atoms and molecules due to the supply …
