Cheese fortification using saturated monoglyceride self‐assembly structures as carrier of omega‐3 fatty acids 下载免费PDF全文

The purpose of this research was to study the capacity of emulsions containing saturated monoglyceride self‐assembly structures to deliver omega‐3 fatty acids in fresh soft cheese. To this aim, fortified emulsions containing different ratios of milk, saturated monoglycerides (MGs) and cod liver oil were added to milk before cheese‐making. These emulsions were characterised by distinct microstructural features observed by polarised light microscopy and apparent viscosity values. The omega‐3 delivery performance of MG emulsions highlighted that this strategy allowed a good retention of the omega‐3‐rich oil in the curd (up to 75%). The fortified cheeses showed yield value and fat content higher than those of control samples. The enriched cheese showed hardness and cohesiveness obtained by texture profile analysis similar to those of the unfortified product. Only a slight decrease in gumminess was detected in fortified cheese. 相似文献

Synthetic analogs of titanate ceramics (perovskite and zirconolite) designed for use as a matrix for immobilization of high-level
nuclear fuel reprocessing wastes (HLW). Such ceramics have been prepared by SHS method from a mixture of titanate ceramics
and non-radioactive model oxides. Synthesis conditions have been optimized. The synthesized low-porosity cylindrical compacts
exhibited a high strength and low rate for leaching Cs, Sr, Y, Ce, and La in bidistilled water. The phase composition and
microstructure of synthesized products have been characterized. The immobilization of Cs was found to be accompanied by a
marked loss of this element.

In this work, the synthesis and characterization of ZnS nanoparticles prepared via two approaches, involving the thermal decomposition of the precursor complex in a furnace (pyrolysis) and by solvothermal process in the presence of hexadecylamine (HDA-ZnS), are reported. The precursor complex, Zinc (II) bis (N,N-diallyl dithiocarbamate), was synthesized and characterized by spectroscopic and single-crystal X-ray techniques. The spectroscopic analyses of the complex indicated a symmetrical bidentate coordination of the dithio ligand through the S-atoms. The single-crystal X-ray structure revealed a distorted square pyramidal coordinate geometry with S atoms around the Zn ion. The optical properties and the morphology of the as-prepared nanoparticles were studied by UV-Vis and photoluminescense spectroscopy, and transmission electron microscopy (TEM), respectively. HDA-ZnS are spherical and monodispersed with an average size of 4.5?nm, as estimated from the optical absorption spectrum and the TEM image. The ZnS nanoparticles obtained via pyrolysis in a furnace yielded the hexagonal wurtzite phase, whereas the HDA-ZnS nanoparticles showed a mixture of wurtzite and cubic phase with the cubic phase being dominant. 相似文献
