Flocculation 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 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...
متن کاملInteraction of Guar and Xanthan Gums with Starch in the Gels Obtained from Normal, Waxy and High-amylose Corn Starches
The objectives of the present study were to analyze the chemical interactions between guar and xanthan gums and starches. Gels were obtained from normal (NCS), waxy (WCS) and high-amylose (HACS) corn starches containing gums. The gels were evaluated according to their pasting properties and infra-red absorption. The guar (GG) and xanthan (XG) gums affected the properties of the NCS paste more s...
