abstract methane concentrations in kano municipality have been attributed to the burning of solid and fossil fuels and industrial processes. using an automatic gas sampling system, methane in the kano atmosphere was determined. its distribution in the municipality was skewed towards high frequency of low concentration with a mean and standard deviation of 0.61? 0.39 ?g/m3. similarly the distri...

This review surveyed recent literature focused on factors that affect myoglobin chemistry, meat color, pigment redox stability, and methodology used to evaluate these properties. The appearance of meat and meat products is a complex topic involving animal genetics, ante- and postmortem conditions, fundamental muscle chemistry, and many factors related to meat processing, packaging, distribution...

The aim of this study was to investigate the effect of eugenol treatment and modifi ed atmospheres (50 % N 2 + 50 % CO 2 ) packaging (MAP) on the storage stability of chicken noodles stored at 35 ± 2°C for 90 days. A total four treatments were assigned (i) control aerobic (C-AP), (ii) eugenol treated aerobic (ET-AP), (iii) control MAP (C-MAP), and (iv) eugenol and MAP treated (ET-MAP). All samp...

Herpes simplex type 1 virus (HSV-1) and bacteriophage λ capsids undergo considerable structural changes during self-assembly and DNA packaging. The initial steps of viral capsid self-assembly require weak, non-covalent interactions between the capsid subunits to ensure free energy minimization and error-free assembly. In the final stages of DNA packaging, however, the internal genome pressure d...

Our objective was to assess the effects of lactate enhancement in combination with different packaging systems (vacuum; high-oxygen, 80% O2 + 20% CO2; or 0.4% CO, 30% CO2 + 69.4% N2) on beef Longissimus lumborum and Psoas major steak redness. Subprimals (n = 16) were divided in half and randomly assigned to 1 of 4 injection treatments (non-injected control, water-injected control, 1.25% lactate...

The microbial contamination in food packaging have been a major concern that paved the way for the search for natural based new anti-microbial agents, such as modified α-mangostin. In the present work, twelve synthetic analogs were obtained via semi-synthetic modification of α-mangostin by Ritter reaction, reduction by palladium-carbon (Pd-C), alkylation, and acetylation. The evaluation of the ...
