Agriculture accounts for a large proportion of global greenhouse gas (GHG) emissions. It is therefore crucial to identify effective and efficient GHG mitigation potentials in agriculture, but also in related upstream sectors. However, previous studies in this area have rarely undertaken a cross-sectoral assessment.

Anhydrous milk fat (AMF) is a flavorful, but particularly complex fat containing a wide variety of fatty acids (FAs) and triglycerides (TGs), resulting in an extended melting range of -40 °C to 40 °C. The functionality of this fat can be steered by the addition of sucrose esters (SEs). In this study, the crystallization behavior of AMF in the presence of a stearic-palmitic SE was assessed.

Article Synopsis
  • The study examined how different storage atmospheres affect the color and myoglobin redox state of beef, using six packaging conditions with varying oxygen and nitrogen levels over 14 days at 2°C.
  • The color changes were quantitatively analyzed through non-invasive methods, showing a significant correlation between the vibrant red color (a* values) and oxymyoglobin (OMb) levels, while vacuum packaging provided better color stability.
  • Results indicate that while high oxygen levels create attractive meat color, they compromise overall stability, suggesting optimal storage atmospheres for maintaining color quality in various commercial scenarios.

Bone fractures often require internal fixation using plates or screws. Normally, these devices are made of permanent metals like titanium providing necessary strength and biocompatibility. However, they can also cause long-term complications and may require removal.

In the last decade, research has focused on examining the fundamental interactions occurring in triglycerides, aiming to comprehend the self-assembly of crystalline nanoplatelets (CNPs) and their role in forming larger hierarchical structures essential for fat functionality. Microscopy research on CNPs frequently requires disruptive preparatory techniques, such as deoiling and sonication, to achieve quantitative outcomes. Conversely, X-ray scattering has proven to be an advantageous method for studying triglycerides, as little sample is needed to quantify the system's hierarchical structures.
