due to the need to find new protein sources with considering the fact that the bitter vetch seed has high levels of protein content, physicochemical and mechanical properties of bitter vetch seed and functional properties of its flour were evaluated in this study. the effects of altering the ph on protein solubility, foaming capacity, foaming stability, emulsion capacity and emulsion stability ...

The present study was planned to improve the stability of dithranol using solid dispersions (SD). Two different SD at a 1:9 ratio of dithranol/excipient were prepared: one of them using glyceryl behenate as excipient and the other using a mixture of argan oil with stearic acid (1:8 ratio) as excipient. Pure dithranol and SD of dithranol were incorporated in an oil-in-water cream and in a hydrop...

Compressed wood, which is formed by a process that increases the wood’s density, aims to improve its strength and dimensional stability. Compressed wood can be used in building and construction, especially for construction of walls and flooring. Currently, supplies of wood are becoming limited, and the oil palm tree has become one of the largest plantation species in Malaysia. Oil palm trunk co...

With increasing oil exploration in Arctic regions, the risk of an accidental oil spill into the environment is inevitably elevated. As a result, concerns have been raised over the potential impact of oil exposure on Arctic organisms. This study assessed the effects of an acute oil exposure (mimicking an accidental spill) on the immune function and oxidative stress status of the Arctic scallop C...

Despite their lack of thermodynamical stability, nanoemulsions can show a remarkable degree of kinetic stability. Among the various different preparation methods the phase-inversion concentration method is particularly interesting as it occurs spontaneously. Here we investigate such a system composed of a surfactant, cosurfactant, and oil that upon dilution with water forms long time metastable...

The aim of present study was to compare the effects of ultrasound-assisted and microwave-assisted extraction with solvent extraction method on antioxidant activities of jujube (Ziziphus mauritiana Lam.) leaf extracts in stability of sunflower oil during deep frying. The antioxidant activities of the extracts were evaluated by using 2, 2-diphenyl-1-picrylhydrazyl (DPPH˙) radical scavenging and β...

16 Starches with different amylopectin contents and different molecular sizes prepared 17 using acid hydrolysis were hydrophobically modified using octenylsuccinic anhydride 18 (OSA). The OSA-modified starches were used as surfactants to stabilize emulsions of 19 β-carotene and canola oil dispersed in water. The objective of this study is to 20 investigate the relationship between starch molecu...

A linear and weakly nonlinear stability analysis is performed for speci c two-layer systems which have been examined experimentally in Degen et al (Phys Rev E 57, 6647 (1998)). For their water/silicone oil system, at the depth fraction where oscillations are predicted, many wavelengths are unstable. The neutral stability curve is rather at in this region, and oscillations begin slightly above t...
