information on the thermophysical properties of the iranian ultrafiltrated (uf) white cheese is very limited. in this research, those thermal properties determined experimentally were thermal conductivity, specific heat, density and water activity. the thermal conductivity and specific heat of iranian ultrafiltrated white cheese (iufwc) ranged from 0.447 to 0.480 w m-1 °c-1 and from 3.871 to 4....

Solutions at high salt concentrations are used to crystallize or segregate charged colloids, including proteins and polyelectrolytes via a complex mechanism referred to as "salting-out". Here, we combine small-angle X-ray scattering (SAXS), molecular dynamics (MD) simulations, and liquid-state theory to show that salting-out is a long-range interaction, which is controlled by electrolyte concen...

In their Perspective 1 based on recent work of the group, 2 Xie and Gao outline a simple theory for rationalizing the specific effects of ions on proteins, i.e., the Hofmeister series. 3 Their approach is thermodynamic, based on activity coefficients, surface tension and solubility data. It is also systematic, detailing individual contributions to the overall protein salting-out/salting-in and ...

Despite the fact that ionic liquid-based aqueous two phase systems (ATPSs) have been widely studied for extraction purposes, the adequacy of biodegradable organic salts as salting out agents has been left unexploited. In this study, we investigated the ability of sodium-based organic salts in the formation of ATPS in the presence of a common ionic liquid, [C4mim]BF4. In the pioneering aspect of...

Accurate calculation of light hydrocarbon solubilities in aqueous electrolyte solutions is critical for petroleum and geochemical applications. However, very few Equations State (e-EoS) have been used solubilities. Thermodynamic gas (methane ethane) chloride salts are presented. This work introduces a new parameter estimation approach (which can predict well the liquid densities solutions) Cubi...

This paper discusses how the validity of road safety evaluation studies can be assessed by analysing causal chains. A causal chain denotes the path through which a road safety measure influences the number of accidents. Two cases are examined. One involves chemical de-icing of roads (salting). The intended causal chain of this measure is: spread of salt --> removal of snow and ice from the road...

The presence of black spots on dry-cured Iberian ham surface is an alteration related to microbial population. Although it provokes important economic losses for the meat industry, the microorganisms responsible for this spoilage still remain unclear. The aim of this study was to identify the microorganisms involved in dry-cured Iberian ham black spot spoilage and to study the conditions affect...

background: dna extraction is one the most important steps for molecular analysis of food-borne pathogens. in this research, three methods of dna extractions from beef harboring sarcocystis spp. were compared for the quality, quantity, safety, as well as cost-effectiveness. methods: about 100 mg intersostal and diaphragm were collected from 10 slaughtered cattle. after ensuring their contaminat...

Salted fish preparations are popular and widely eaten across the world. Salting is a preservation strategy to enhance shelf life by decreasing water activity in muscles. demand increases with less regard for characteristics, novel strategies required healthy production. Lysozyme, EDTA, their mixture, black cumin oil nanoemulsion (BCN) were used dipping treatments make preservative films before ...
