| Effect of bovine feeding system (pasture or concentrate) on the oxidative and sensory shelf life of whole milk powder. |
Feed sources and Nutrition | Whole milk powder is an important product that is often exported to be reconstituted and used for various purposes. The spray drying to obtain the product enables milk to be easily transported and stored for extended periods of time. However, the spray drying process can also facilitate oxidative changes as the high fat content is exposed to elevated temperatures, resulting in reduced shelf life due to off-flavour development. Moreover, whole milk powder can also be subjected to extreme temperature fluctuations during transport and storage, further affecting oxidative stability. |

| Lactose oxidase: An enzymatic approach to inhibit Listeria monocytogenes in milk. |
Food Safety and Quality | Listeria monocytogenes is a pathogen which may cause listeriosis with sometimes grave consequences. It is a ubiquitous, gram-positive, facultative anaerobe that grows at refrigeration temperatures and is found throughout the environment, specifically in soil and water. Listeria monocytogenes may survive in food that has a relatively high acid and salt content and can tolerate high and low temperatures. |
