Assessment of the variation of marbling and intramuscular fat content of beef, and validation of possible factors to increase sensory beef quality
(2021-11)
This thesis focuses on the intramuscular fat content (IMF) or the marbling of beef as main parameters of sensory beef quality. The aim is to identify the high variability of these traits and to verify possible influences such as genetics, age, gender and feeding strategies to increase marbling.
The first part of this research focuses on the variation of quality traits within a genetically homogeneous line of an endangered German beef cattle breed “Rotes Höhenvieh” (RHV). The intramuscular fat content of beef samples ...

Denaturation mechanism of whey protein by using the hot extrusion technology
(2022-02)
Milk proteins are one of the heat-sensitive nutritional components, especially whey proteins changing their structure through thermal treatment, consequently denaturizing and aggregating. The transformation of native whey proteins structure in presence of shear stress resulted in the microparticulation, which affected the functional properties. Many authors investigated these parameters with different conditions; however, understanding the combination of relevant parameters of the microparticulation process of whey ...

Process optimisation and non-destructive quality attributes monitoring during drying: A case study of celeriac slices and characterisation of its powder
(2023)
This study investigated strategies applied in drying technology to produce an optimised quality of plant-sourced food while considering environmental and sustainability aspects based on a case study of celeriac and powder, respectively. The I-optimal design of response surface methodology with 30 experiment runs was applied for process optimisation. Pre-drying treatments (blanching at 85 °C, 3 min; dipping in 1% citric acid solution, 3 min; no pre-drying treatment), drying temperatures (50, 60, and 70 °C), air ...

Analysis of agricultural landscape transformation and cropping system diversification in southern Myanmar
(2023)
Myanmar's forests are rich in biodiversity and have significant potential for carbon reduction. Kyunsu Township in southern Myanmar is still covered by biodiverse tropical evergreen rainforests on the highlands and mangroves on the coastline, conserving carbon stocks. However, the expansion of croplands into these forests to meet the growing demand for food and crop income is a major driver of deforestation and loss of carbon sinks. Thus, balancing agricultural land use and natural resource conservation is vital for ...

Management factors influencing cow milk quality and safety in the Indian megacity of Bengaluru
(2023)
Ensuring animal welfare is a critical priority for livestock farmers in the face of urbanization. Rapid urban growth increases the demand for animal products but decreases availability of arable land around cities with negative implications for animal feed production. In urbanizing regions, livestock keepers resort to common pool resources for animal nutrition. Yet, the repercussions of urbanization on the quality of common pool feed resources, animal health, production and product safety, remain unstudied. Additionally, ...
