Response surface optimization of acid modification on mung bean starch
This research shows the dependence of number average degree of polymerization (DPn) of mung bean starch (MBS) on starch slurry concentration, acid/starch slurry ratio, time and temperature in acid modification process. Optimizing these factors to earn as low as possible DPn was evaluated by using the Response Surface Methodology (RSM) with reduced Central Composite Face-Centered (reduced CCF) m...
متن کاملModeling and Optimization of the Coagulation–Flocculation Process in Turbidity Removal from Aqueous Solutions Using Rice Starch
Natural coagulants have received much attention for turbidity removal, thanks to their environmental friendliness. The present study investigates potential application of rice starch for removal of turbidity from aqueous solutions. It considers the effects of four main factors, namely settling time (40-140 min), pH (2-8), slow stirring speed (20-60 rpm), and rice starch dosage (0-200 mg/L), eac...

متن کاملModification and Chemical Characterization of Barley Starch
Acetylation is a chemical modification for estherification, in which hydroxyl groups are replaced with acetyl groups that offers him major stability, changing the physicochemical and functional properties of the starches. Acetylated starches presents 6-10 ° C less at the gelatinization temperature and the maximum peak viscosity is greater than that of a native starch, so are more readily disper...
متن کاملSurface Chemical Compositions and Dispersity of Starch Nanocrystals Formed by Sulfuric and Hydrochloric Acid Hydrolysis
Surface chemical compositions of starch nanocrystals (SNC) prepared using sulfuric acid (H2SO4) and hydrochloric acid (HCl) hydrolysis were analyzed by X-ray photoelectron spectroscopy (XPS) and FT-IR. The results showed that carboxyl groups and sulfate esters were presented in SNC after hydrolysis with H2SO4, while no sulfate esters were detected in SNC during HCl-hydrolysis. TEM results showe...
