Characterization of normal and waxy corn starch for bioethanol production.
Objectives of this study were to compare ethanol production between normal and waxy corn using a cold fermentation process and to understand effects of starch structures and properties on ethanol production. Ethanol yields positively correlated (p < 0.01) with starch contents of kernels of the normal and waxy corn. The average starch-ethanol conversion efficiency of waxy corn (93.0%) was substa...
متن کاملFlocculation of kaolin by waxy maize starch phosphates
Waxy maize starch phosphates were tested as flocculants in order to determine if they have the potential to replace petroleum-based polymer flocculants currently used commercially. Phosphorylation was carried out by dry heating of starches and sodium orthophosphates at 140 C for 4 h. Native and phosphorylated waxy maize starches were ineffective as flocculants for kaolin in deionized water. How...
متن کاملAdenosine diphosphoglucose-starch glucosyltransferases from developing kernels of waxy maize.
TWO ADENOSINE DIPHOSPHOGLUCOSE: alpha-1,4-glucan alpha-4-glucosyl-transferases were extracted from kernels of waxy maize harvested 22 days after pollination and separated by gradient elution from a diethylaminoethyl-cellulose column. Both fractions could utilize amylopectin, amylose, glycogen, maltotriose and maltose as primers. The rate of glucose transfer from adenosine diphosphoglucose to ra...
متن کاملThermomechanical characterization of an amylose-free starch extracted from cassava (Manihot esculenta, Crantz).
The aim of this study was to determine and compare the melting (Tm), glass transition (Tg) and mechanical relaxation (Tα) temperatures of a new waxy cassava starch. Thermal transitions measurements were obtained by Differential Scanning Calorimetry (DSC) and Dynamical Mechanical Thermal Analysis (DMTA). The experimental data showed a high correlation between water volume fraction and melting te...
متن کاملPreparation and structure of Octenyl succinic anhydride modified waxy maize starch, microporous starch and maltodextrin
Octenyl succinic anhydride (OSA) modified starch is widely used in emulsion and encapsulation applications. The functionality of OS starch depends on its molecular structure. A systematic study was performed to investigate the reaction of OSA with granular waxy maize (WM) starch, microporous WM starch and soluble maltodextrin. OS starches were prepared in an aqueous slurry system, and the degre...
