Proteins isolated from sweet potatoes (Ipomoea batatas) have been shown to possess antidiabetic, antioxidant, and antiproliferative properties. The objective of this study was to chemically optimize a process for extracting proteins from sweet potato peel. The extraction procedure involved mixing peel with saline solvent to dissolve proteins and then precipitating with CaCl2. Quadratic and segm...

This paper experimentally studies the mass transfer during the dehumidification/regeneration operation using the hygroscopic material calcium chloride and calcium chloride dehydrate as desiccant. These desiccants are compared on the basis of the same operation conditions. According to the analysis of heat and mass transfer processes, the key influencing factors are relative humidity and regener...

An L-form isolated from Escherichia coli K12 by sequential treatment with N-methyl-N'-nitro-N-nitrosoguanidine and lysozyme was adapted to grow in hyperosmolar liquid cultures. It was stable in the absence of antibiotic when cultured in brain heart infusion (BHI) broth containing NaCl and CaCl2, the optimal concentrations being 0.34 M and 1 mM, respectively. No growth of the L-form was observed...

The objective of this study was to evaluate the effect of the concentration of calcium chloride (CaCl2) solution on the surface hardness of restorative glass ionomer cements (GICs). Two high-viscosity GICs, Fuji IX GP and GlasIonomer FX-II, were immersed in several concentrations of CaCl2 solution for 1 day and 1 week. The immersed specimen surfaces were evaluated using microhardness testing, g...

To improve storage/shipping quality of sweet cherry (Prunus avium L.), the effect of calcium chloride (CaCl2) added to hydro-cooling water on physiological and biochemical processes related to fruit and pedicel quality was investigated on two major cultivars. The fruit tissue Ca content increased up to 29-85% logarithmically for 'Sweetheart' and 39-188% linearly for 'Lapins' as CaCl2 rate incre...

The efficiency of the application of a chemically-modified activated carbon surface was investigated. The purpose of this study was to examine the effect of treatment with CaCl2 solution at a concentration of 2000 mg.L on the sorption of nitrate ions from aqueous solutions in successive sorption/t reatment cycles. The sorbent was initially subjected to chemical treatment with CaCl2 and subseque...

To develop a practical method of treating boron-containing wastewater, we custom designed two laboratory-scale continuousflow-type hydrothermal mineralization apparatuses. We carried out a hydrothermal treatment using a continuous-flow apparatus, using Ca(OH)2, CaCl2, and both Ca(OH)2 and CaCl2 as mineralizers, under various pH conditions. Our results show that using CaCl2 under optimal pH cond...

The influence of ionic strength and the molecular weight of polyacrylic acid (PAA) on its adsorption and the structure of adsorbed polymer layer on SiO2 surface in the presence NaCl and CaCl2 was measured. Thickness of PAA adsorption layers on the SiO2 surface in these two electrolytes were also measured as well as the expansion coefficient (α) of PAA in CaCl2. The increase of: ionic strength, ...
