Enzymatically modified starch with controllable digestibility may find unique applications. In the present study, side chains of amylopectin were elongated by amylosucrase, followed by debranching with pullulanase to produce linear chains that self ...

Molecular weight heterogeneity in starch amylopectins
Journal of Polymer Science, 1957AbstractThe number‐average molecular weight of a corn amylopectin sample is concluded to be approximately 300,000 on basis of both osmotic pressure and reducing group determination. The weight‐average molecular weight of this preparation was previously shown to be approximately 80 × 106.

Starch and Amylopectin — Rheological Behavior of Gels
Starch - Stärke, 1994AbstractRheological behavior of starch and amylopectin gels was evaluated by small amplitude oscillatory testing using the storage modulus (G′), loss modulus (G″) and the complex viscosity (n*). It was found for the three starches (normal and waxy corns, and amaranth) that at low frequency the viscous component G″ had a major contribution on the gel ...

Amylopectin structure of heat–moisture treated starches
Starch - Stärke, 2012AbstractThe effects of heat–moisture treatment (HMT; moisture content of 25%, at 100°C for 24 h) on starch chain distribution and unit chain distribution of amylopectin in normal rice, waxy rice, normal corn, waxy corn, normal potato, and waxy potato starches were investigated. After HMT, starch chain distribution (amylose and amylopectin responses) of

In vitro enzymatic hydrolysis of amylopectins from rice starches
International Journal of Biological Macromolecules, 2017The effects of the molecular structures of amylopectins on the enzymatic hydrolysis of waxy-rice amylopectin (WRA) and normal-rice amylopectin (NRA) were investigated. The results indicated that compared to NRA, WRA possessed larger chain length, number of chains, internal chain length, degree of polymerisation, interblock chain length, and lower ...

The fine structures of pumpkin, potato, wheat, cassava, and pea starches were determined, followed by an evaluation of how these structures affected the properties of starch films. The structures significantly influenced film properties.

Determination of Amylose: Amylopectin Ratios of Starches
Starch - Stärke, 1981AbstractA method has been developed for the determination of amylose: amylopectin ratios of starches which offers an alternative to iodimetric methods. Starches solubilized in dimethylsulphoxide were debranched with isoamylase and the resulting linear components quantitated by gel permeation chromatography on a column of Sepharose CL‐6B.

Phosphate esters in amylopectin clusters of potato tuber starch
International Journal of Biological Macromolecules, 2011Starch phosphate is important in starch metabolism and in order to deduce its location and structural effects in clusters and building blocks of amylopectin, these were isolated from a normal potato (WT) and two starches with antisense suppressed glucan water dikinase (asGWD) activity and starch branching enzyme (asSBE) activity possessing suppressed ...

Enzymatic modification of starch: A green approach for starch applications.
Carbohydrate Polymers, 2022Native starches are modified to overcome the shortcoming, including retrogradation, syneresis, and low water-holding potential, which limit their industrial applications. The enzymatic modification includes designing a starch with a new structure.
