The aim of this work was to characterize starch polysaccharides using asymmetrical flow field fractionation coupled with multiangle laser light scattering. Amylopectins from eight different botanical sources and rabbit liver glycogen were studied. completely solubilized analyzed, high mass recoveries achieved (81.7−100.0%). Amylopectin M̄w, R̄G, the hydrodynamic coefficient νG (the slope log−log plot RGi vs Mi) within ranges 1.05−3.18 × 108 g mol-1, 163−229 nm, 0.37−0.49, respectively. data...
"Mapuey" tubers in Venezuela are staple food for indigenous peoples from the Caribbean coast and Amazon regions. Noticeable differences between genotypes of yam starches were observed. Granules large, triangular, or shell-shaped with monomodal particle size distribution 24.5 35.5 μm. Differential scanning calorimetry (DSC) analyses revealed onset gelatinization temperatures 69.1 to 73.4 °C high enthalpy changes 22.4 25.3 J g−1. All X-ray diffractograms exhibit B-type crystallinity....
Abstract Granule sizes, macromolecular features and thermal pasting properties of starches from seven tropical sources (Florido, Kponan Esculenta yams, cocoyam, cassava, sweet potato ginger) were compared with those several well‐known cereal, legume tuber starches. The aim the study was to characterise some non‐conventional a view possibly marketing them. Amylose content varied 148 mg g −1 in starch 354 smooth pea starch. For total starches, weight‐average molar mass ( M̄ w ) ranged between...
Synthetic amyloses, pullulans, phytoglycogen, rabbit liver glycogen, oyster and dextrans were studied using high-performance size-exclusion chromatography combined with multiangle laser light scattering (MALLS) online quasi-elastic (QELS), which provided the RH distributions up to 65 nm. Different structural parameters extracted from entire molar mass distributions, including slope of log-log plot R H(i) versus M(i)and rho(i )= R(Gi)/R(Hi)ratio. This approach enabled observe deviations De...
The destructuration of native maize starch in mixtures water and ionic liquids (ILs) containing acetate anions was studied dynamic heating conditions, combining calorimetry, rheology, microscopy chromatographic techniques.
A new α-amylase from Rhizomucor sp. (RA) was studied in detail due to its very efficient hydrolysis of raw starch granules at low temperature (32 °C). RA contains a binding domain (SBD) connected the core amylase catalytic by O-glycosylated linker. The mode degradation native maize and, particular, changes structure during hydrolysis, monitored for concentrations varying between 0.1 and 31%. compared porcine pancreatic (PPA), which has been widely either on resistant or as model enzyme solid...
Biopolymers from agricultural starchy commodities can be raw materials for edible, biologically degradable plastics. They have promising uses, having been proposed replacing synthetic films. There are several sources not yet quite exploited such as tropical roots and tubers that could excellent starch to produce edible films with distinctive functional properties. The objective of this study was formulate six crops. Starches were extracted purified 97–99% purity Ipomoea batatas, Arracacia...
