Starch granules were prepared from 14 double- and 26 triple-mutants containing amylose-extender (ae), 14 double- and 18 triple-mutants containing waxy (wx), 15 double- and 20 triple-mutants containing sugary-1 (su1), 13 double- and 23 triple-mutants containing sugary-2 (su2), and 14 double- and 19
On the basis of interallelic recombination frequencies measured in diallelic crosses of the 5 amylose-extender alleles in maize, ae, B1, B3, M2 and i1, it was possible to construct a unique linear genetic map ordering all 5 alleles within the locus. The reciprocal diallelic crosses each gave
Content and composition of maize endosperm lipids and their partition in the floury and vitreous regions were determined for a set of inbred lines. Neutral lipids, i.e., triglycerides and free fatty acids, accounted for more than 80% of endosperm lipids and are almost 2 times higher in the floury
The influence of starch type (resistant starch (RS) versus native (NS) starch) and concentration (10 and 35wt.%) on the potential gastrointestinal fate of digestible lipid (corn oil) droplets encapsulated within starch hydrogels was studied using a simulated gastrointestinal tract (GIT). The NS used
Metabolite levels in kernels of selected starch-deficient mutants of maize (Zea mays L.) were investigated to gain insight into partitioning of carbohydrate metabolism during kernel development. Several free sugars, hexose phosphates, triose phosphates, fructose-2,6-bisphosphate, and pyrophosphate
Starch branching enzymes (SBE) catalyze the formation of [alpha]-1,6-glucan linkages in the biosynthesis of starch. Three distinct SBE isoforms have been identified in maize (Zea mays L.) endosperm, SBEI, IIa, and IIb. Independent genes have been identified that encode maize SBEI and IIb; however,
The consumption of fruits, vegetables, and whole grains rich in antioxidative phytochemicals is associated with a reduced risk of chronic diseases such as cancer, coronary heart disease, diabetes, Alzheimer's disease, cataract, and aged-related functional decline. For example, phenolic acids are
Starch, which includes amylose and amylopectin, is the most important component in maize (Zea mays L.) seeds. The accumulation of amylose in maize seeds was examined in this study. The percentage of amylose content gradually increased in seeds from day 10 to day 25 after pollination, which is
In this paper, Single and dual modification with etherification and Cross-linking of Zea mays starch were homogeneously carried out and in [BMIM]Cl ionic liquid media (IL), an excellent solvent for the starch modification using sodium monochloroacetic acid and sodium trimetaphosphate in different
This study aimed to understand effects of adding corn oil (CO) and soy protein (SP) to corn starch on the physicochemical properties and digestive rates of annealed starch complex and mechanisms of interactions between corn starch (CS), CO and SP. Binary and ternary blends were prepared using CS
Annealing effects on the structure characteristics and the digestibility of corn starch (CS)/corn oil (oil)/lysine mixture were investigated. The objective of this study was to provide guidance for designing higher slowly digestible starch. Confocal laser confirmed that lysine adhered to granules
Glass transition temperatures and physical aging of amorphous cassava starch and their blends with corn oil were assessed by differential scanning calorimetry (DSC). Two enthalpic relaxation endotherms, well separated in temperature values, were exhibited by neat amorphous cassava starch with 10.6%
The amylose and amylopectin fractions from kernel starch synthesized shortly after exposure of intact Zea mays L. plants to (14)CO(2) had similar specific radioactivities (counts per min per mg of carbohydrate). In both fractions the radioactivity was distributed throughout the molecules. These data
During the processing of corn syrup for commercial use, starch, in the form of alpha -amylose, must be completely broken down to its D -glucopyranose units. Sodium metabisulfite is added to the corn syrup as a preservative. Flow Injection Coulometry was used to perform an automated assay of these
