Insight in the regioselective enzymatic transgalactosylation of salicin catalyzed by beta-galactosidase from Aspergillus oryzae
(Elsevier Sci Ltd, Oxford, 2015)
In this study, enzymatic synthesis of galactoside of salicin, compound with potential physiological activity due to structural resemblance with galectin inhibitors, and analgesic and antipyretic properties of salicin, was ...
Recovery of (-)-epigallocatechingallate (EGCG) from aqueous solution by selective adsorption onto spent coffee grounds
(Springer, New York, 2015)
Activated carbons from spent coffee grounds have been prepared for column adsorption of main green tea polyphenol (-)-epigallocatechingallate (EGCG). The response surface methodology was used to estimate the influence of ...
Optimization of extraction of stinging nettle leaf phenolic compounds using response surface methodology
(Elsevier, Amsterdam, 2015)
A full three level factorial design was implemented for optimization of extraction parameters in order to maximize total phenolic (TP) yield from stinging nettle leaf. Factors considered were percentage of methanol in ...
Optimisation of microwave-assisted extraction parameters for antioxidants from waste Achillea millefolium dust
(Elsevier Science Bv, Amsterdam, 2015)
Microwave-assisted extraction of polyphenols and flavonoids from waste Achillea millefolium (yarrow) dust was optimised using the response surface methodology. The influence of the extraction time (13-47 s), ethanol ...
Production of Antioxidant Egg White Hydrolysates in a Continuous Stirred Tank Enzyme Reactor Coupled with Membrane Separation Unit
(Springer, New York, 2015)
The objective of this research was to design an efficient continuously operated membrane reactor with a separation unit for egg white protein (EWP) hydrolysis and production of hydrolysates with improved antioxidant ...
Experimental Design Optimization of the Determination of Total Halogens in Coal by Combustion-Ion Chromatography
(Taylor & Francis Inc, Philadelphia, 2015)
Determination of total halogens in coal was investigated with oxygen bomb combustion followed by ion chromatography. Experimental parameters were optimized by fractional factorial design and response surface methodology. ...
