Insights into kinetic, isotherm, and thermodynamic of ultrasound mode- and amplitude-dependent carotenoid and chlorophyll degradation or/and adsorption.

Experimental data were analyzed to investigate the underlying adsorption or degradation mechanism of carotenoids and chlorophylls over the bleaching of sunflower oil through different amplitudes of horn and bath ultrasound (ultrasound-assisted bleaching; UAB), temperature, time, and bleaching clay. Quantifying the color removal efficiency in both batch and continuous systems, along with the corresponding process time and energy consumption, is paramount for evaluating the energy-related performance of the treatment method. The adsorption of pigments onto activated bentonite was notably rapid and effective when ultrasound was employed.

Investigation of cryoprotectants-treated surimi protein deterioration during chilled and frozen storage: Functional properties and kinetic modeling.

The relative cryoprotective effects of flaxseed protein hydrolysate and pectin in comparison with conventional cryoprotectant (sucrose + sorbitol + sodium tripolyphosphates) on stabilization of proteins in surimi of Capoor () were investigated during freezing (-20°C for 4 months) and chilling storage (4°C for 10 days). Although pectin caused to improve water-holding capacity (27.8%; 4°C and 21.

The correlation among residual nitrites, biogenic amines, N-nitrosamine formation, and degradation occurrence of punicalagin α/β, rosmarinic acid, carnosol, and carnosic acid in extract-treated sausage during storage.

The aim of this study was to investigate the relation between residual α- and β-punicalagin in L.; PPE and rosmarinic acid, carnosol, and carnosic acid in (SE) with residual nitrites, biogenic amines (cadaverine, putrescine, and histamine), N-nitrosodimethylamine (NDMA), microbial counts, lipid oxidation indices, and color values in extract-treated sausage over 14 days of storage. Sausage containing SE + nitrite 60 ppm (SSN) showed minimum levels of the residual nitrites (13.

Optimization of Ni(II) adsorption onto Cloisite Na clay using response surface methodology.

The aim of this study was to investigate the adsorption of Ni(II) from aqueous solutions onto Cloisite Na clay. The effects of the initial concentration of Ni(II), adsorbent dose, pH, and temperature on adsorption capacity were studied using response surface methodology. A second-order regression model was determined based on the experimental results.

Bis[(2-amino-phen-yl)methanol-κO,N]bis-(nitrato-κO)manganese(II).

In the title compound, [Mn(NO(3))(2)(C(7)H(9)NO)(2)], the Mn(II) atom (site symmetry 2) is coordinated by two N,O-bidentate (2-amino-phen-yl)methanol ligands and two monodentate nitrate anions in a distorted cis-MnN(2)O(4) octa-hedral coordination geometry. In the crystal, N-H⋯O, O-H⋯O and C-H⋯O hydrogen bonds help to establish the packing.
