Structural characteristics and stability of films of 1-monostearin accepted as food emulsifiers have been studied as a function of temperature and ethanol concentration in aqueous subphase. The compression isotherms were obtained using an automated Langmuir-type film balance. Temperatures betwee...
Changes in the structural characteristics and stability of monostearin monolayers in the presence of electrolytes in the aqueous subphase were studied. Compression isotherms for monolayers on aqueous NaCl (0.1, 0.5, and 1 mol 1−1) and CaCl2 (0.1 and 0.5 moll−1) solutions were obtained using an a...
Nanostuctured lipid carriers (NLC) consisted of solid lipid and liquid lipid are a new type of lipid nanoparticles, which offer the advantage of improved drug loading capacity and release properties. In this study, solvent diffusion method was employed to produce NLC. Monostearin (MS) and capryl...
The effect of processing conditions on the formation and stability of a gel comprised of oil, water, monostearin and stearic acid was studied. Processing conditions (homogenization rate (10,000–30,000 rpm), cooling rate (0.05–20 °C/min), homogenization temperature (70–95 °C)) had no effect ...
The monostearin monolayer at the air-aqueous interface is more expanded in presence of glycine and at higher temperature from both the surface pressure—area per molecule (π–A) isotherms and static elasticity—surface pressure (Es–π) curves. The dilational viscoelastic properties of monostea...
In this study, enzymatic transesterification of ethyl ferulate (EF) and monostearin for feruloylated lipids production was investigated. Enzyme screening and the effect of feruloyl acceptors on the transesterification were also studied. Effects of reaction variables (reaction temperatures, enzym...
Recognition that trans and saturated fats have negative health effects drive researchers to develop alternative systems that can structure liquid oils into semi-solid plastic pastes for food applications. Monoacylglicerols (MAG) can be used as a promising molecule to achieve this structuring so ...
The present article offers an intensification effort for the synthesis of glycerol monostearate (monostearin, a phase change material) using Amberlyst 36 (wet) catalyst. This work demonstrates the superiority of rotating batch reactor (RBR) over the stirred batch reactor (SBR) in glycerol (GL) –...
