Comparison of the Structure and Properties of Hydroxypropyl Starch/Carrageenan Blends with Different Amylose/Amylopectin Contents [PDF]

Gels
To compare the structure and properties of hydroxypropyl starch/carrageenan blends with different amylose/amylopectin contents, two types of hydroxypropyl starch—a high-amylose type (amylose content > 70%) and a high-amylopectin type (amylopectin content

Resistant Starch Type 5 Formation by High Amylopectin Starch-Lipid Interaction. [PDF]

Foods
The formation of resistant starch type 5 (RS5), primarily associated with amylose–lipid complexes, is typically attributed to starches with high-amylose content due to their affinity for lipid interactions. Recently, studies have also investigated the potential of amylopectin-rich starches to form amylopectin–lipid complexes (ALCs), expanding RS5 ...

Slow hydrolysis of amylose in soluble starch and amylopectin in suspendable starch liberated from non-glutinous rice flour heated with a sorghum extract

Heliyon, 2022
Polyphenols in plant can interact with amylose and amylopectin in different ways affecting their hydrolysis by α-amylase. Pancreatin liberated starch from non-glutinous rice flour heated with and without an aqueous extract of sorghum seeds, and ...

Replacement of the endogenous starch debranching enzymes ISA1 and ISA2 of Arabidopsis with the rice orthologs reveals a degree of functional conservation during starch synthesis. [PDF]

PLoS ONE, 2014
This study tested the interchangeability of enzymes in starch metabolism between dicotyledonous and monocotyledonous plant species. Amylopectin--a branched glucose polymer--is the major component of starch and is responsible for its semi-crystalline ...

Determination of amylose/amylopectin ratio of starches [PDF]

Journal of Inherited Metabolic Disease, 2015
Dear editor, Nalin et al 2014, in a paper recently published in the JIMD, tested in vitro digestion of seven different starches in a dynamic gastro-small intestine model (TIM-1), and did not find large differences between different brands of uncooked cornstarches (UCCS) and of a modified starch (Glycosade®) (Correia et al 2008).

Quantification Technologies for the Determination of Amylose/Amylopectin Ratio in Starch and Their Applications in Food Field

Shipin gongye ke-ji, 2022
Natural starch mainly consists of two forms of α-D-glucan, i.e. amylose and amylopectin. The ratio of these two components is not only related to gelatinization, retrogradation, gelation and other physicochemical properties and food functions of starch ...

Construction of Porous Starch-Based Hydrogel via Regulating the Ratio of Amylopectin/Amylose for Enhanced Water-Retention

Molecules, 2021
The performance of hydrogels prepared with traditional natural starch as raw materials is considerable; the fixed ratio of amylose/amylopectin significantly limits the improvement of hydrogel structure and performance.

Starch Branching Enzyme 1 Is Important for Amylopectin Synthesis and Cyst Reactivation in Toxoplasma gondii

Microbiology Spectrum, 2022
Toxoplasma gondii (T. gondii) bradyzoites facilitate chronic infections that evade host immune response. Furthermore, reactivation in immunocompromised individuals causes severe toxoplasmosis.

Physical and mechanical properties of starch films: the role of the cross-linking mechanism through iodine binding capacity

Revista Principia, 2023
In this study, a better knowledge of the influence of cross-linking mechanism on the mechanical properties of starch films is presented. Thus, waxy starch and cassava starch films, cross-linked with trisodium trimetaphosphate (STMP), were produced and ...

On Amylose and Amylopectin of Glutinous Rice Starch

Nippon Nōgeikagaku Kaishi, 1951
(1) Various procedures for the fractionation of glutinous, non-glutinous and sen rice starch have been studied. It is here shown that special caution is necessary for the fractionation of glutinous-rice starch. (2) The intensity of the coloration of starch fraction with iodine (iodine-coloration degree or coloration degree) was used as the indication ...
