Most commercial water contains alkaline earth metal cations such as magnesium, calcium and barium, and anions such as carbonate, bicarbonate, sulfate, silicate, oxalate, phosphate, etc. Different combinations of these anions and cations will give rise to potentially scalant systems, such as calcium carbonate, calcium silicate, calcium sulfate, calcium oxalate, barium sulfate, magnesium sulfate,...

Coprecipitates of heavy metals with Fe oxides may form in contaminated soil, water, and sediment systems, particularly when oxidation-reduction processes are occurring. Once formed, coprecipitates with ferrihydrite could limit heavy metal mobility, solubility, toxicity, and bioavailability in geochemical systems. In this study, Cd, Cu, Pb, and Zn were coprecipitated with Fe by titration to pHs ...

Flours from African breadfruit, corn and defatted soybean were thoroughly mixed in a Hobart_-mixer at three variable, with the following combinations 40:5:55, 55:5:40, 70:5:25, 85:5:10 and 100:0:0% for African breadfruit, corn and soybean, respectively. These combinations were hydrated to moisture contents of 15, 18, 21, 24, and 27% and extruded at screw speed of 100, 120, 140, 160 and ISOrpm i...

Recombinant protein expression has become an invaluable tool for academic and biotechnological projects. With the use of high-throughput screening technologies for soluble protein production, uncountable target proteins have been produced in a soluble and homogeneous state enabling the realization of further studies. Evaluation of hundreds conditions requires the use of high-throughput cloning ...

In order to improve the water-solubility of curcumin, the complex between curcumin and hyperbranched poly(amide-ester) was formed by dispering the solid curcumin in hyperbranched poly(amide-ester) aqueous solution. The interaction process was characterized by UV-vis absorption spectroscopy, Fluorescence quenching method, Fourier transformation-infrared spectroscopy, thermogravimetric analysis. ...

1. The investigations dealing with the properties of casein as an acid were reviewed. 2. The solubility of uncombined casein in water was measured at 5 degrees C. and found to be 0.70+/-0.1 mg. of N per 100 gm. of water. 3. Robertson's solubility measurements of casein in bases at various temperatures were recalculated and found to agree well with more recent measurements. 4. By combining the o...

--------------------------------------------------------ABSTRACT----------------------------------------------------------Polymorphism evolved out as a major point of attention for industry as well as regulatory agencies. Many pharmaceutical compounds exist in different crystalline forms and thus exhibit polymorphism. Polymorphism may affect Chemical and Physical Stability, Apparent Solubility,...

date syrup powder is a new product which can be used as sugar substitute. first, the date syrupwas spread out on a foil and placed in the oven at 60°c for 24 hours. date syrup was separated from the foil andgrinded. 2% agar and 2% starch were added and syrup with agar and starch that was in a lumpy shape werecrushed and spread on the foil and placed at 60°c for 24 hours. powdered granules, agar...

on experiment was designed for evaluating the nutritienal characteristics and physico-chemical properties of steam treated sugarcane pith (19 bar, 3 min.) and some other roughages. steam treatment resulted in a significant decreased (p<0.05) in ndf (77 vs. 55%), hemicellulose to cellulose ratio (0.54 vs. 0.10) and increased hemicellulose solubility of and soluble sugar fraction (20 vs. 124 mg/g...

Coconut milk has a higher water content than other contents, so microbes can easily damage and spoil it. To obtain low-moisture powder product, the liquid coconut was dried using Buchi Mini Spray dryer B-290 with inlet temperatures of 150°C, 160°C, 170°C. The researchers added maltodextrin to milk, which had ratio grated 1:3, in concentrations 9%, 10%, 11%, 12%, 13%. addition use drying tempera...
