In this study, the optimal conditions for spray drying of extract made from flesh and peel red pitaya were tested using central composite design (CCD). The response surface methodology was used to evaluate effect inlet air temperature (145 – 155°C) concentration maltodextrin (13-17% w/w) on physicochemical properties powder. regression models accurately predicted retention betacyanin (R2=0.94) ...

Physical properties are one of the ‎drawbacks oil palm wood ‎‎(OPW) and they need to ‎be ‎improved via an appropriate method. The ‎response surface methodology (RSM) based on central composite ‎design (CCD) was used evaluate optimize parameters a hydrothermal treatment ‎and create ‎empirical model mass loss (ML, %), equilibrium moisture ‎content ‎‎(EMC, anti-swelling efficiency (ASE24h, %)‎‏ ‏r...

Production of fibrinolytic enzyme by a newly isolated Paenibacillus sp. IND8 was optimized using wheat bran in solid state fermentation. A 2(5) full factorial design (first-order model) was applied to elucidate the key factors as moisture, pH, sucrose, yeast extract, and sodium dihydrogen phosphate. Statistical analysis of the results has shown that moisture, sucrose, and sodium dihydrogen phos...

Extracellular fungal cellulases are key enzymes for the degradation of lignocellulosic biomass. Greater production of these enzymes could reduce the cost of biofuels production. In this study, the basal medium for cellulase production by a Penicillium janthinellum mutant (EU2D-21) in submerged fermentation conditions was optimized using response surface methodology (RSM). Initial studies using ...

The individual and interactive effects of three independent variables i.e. carbon source (glucose), nitrogen source (sodium nitrate) and inducer (ϵ-caprolactam) on nitrilase production from Fusarium proliferatum were investigated using design of experiments (DOE) methodology. Response surface methodology (RSM) was followed to generate the process model and to obtain the optimal conditions for m...

Green chemistry - also called sustainable chemistry - as the cost-effective and environmentally friendly techniques have been gaining more attention recent years. Here, we introduced a fast, non-toxic and sustainable method to synthesize Ag nanoparticles. Various parameters are involved in the bio-synthesis of Ag nanoparticles/multi-walled carbon nanotubes (Ag/MWf-CNT) composites, including...
