2020年12月1日 · Results showed that both amylose and amylopectin fine molecular structures can equally affect the starch pasting and retrogradation property. Specifically, the amount of amylose long chains and amylopectin short chains are positively correlated with the melting temperatures (Tp and Tc) and enthalpy (ΔH) of retrograded starches.

2022年11月15日 · Pearson correlation analysis suggested the underlying mechanism between amylose and amylopectin molecular structures and starch electrospinning: first, various features of amylopectin molecular structure (the values of AP1, AP2, X AP, and DB) all influence the efficient formation of electrospun starch fibres; and second, amylose molecular ...

2024年12月1日 · The chain length distributions of amylose and amylopectin affected the mechanical properties of starch films by influencing structure ordering, supported by the positive correlation between the double helix content and the tensile strength (r = 0.95, p < 0.05). The amylopectin B1, B2, and B3 chains increased film mechanical strength.

2014年4月23日 · Chain-length distributions (CLDs) of amylose and amylopectin branches (“fine structure”) are characterized using size-exclusion chromatography [sometimes termed gel permeation chromatography (GPC)] and parametrized by both biosynthesis-based and empirical fits, to understand the starch biosynthesis mechanism and identify associations with ...

Fractionated corn amylose and amylopectin, with known molecular weights, chain lengths, and branching and crystalline ratios, were studied for pasting, gel textural, and retrogradation properties by rapid viscoanalysis, textural profile analysis, and differential scanning calorimetry.

2020年8月31日 · Starch granules consist of two types of polymeric components, essentially linear amylose and branched amylopectin. Ratios and fine structure of these two polymers determine the starch functional properties and starch applications in food and non-food industries.

2020年8月31日 · Starch granules consist of two types of polymeric components, essentially linear amylose and branched amylopectin. Ratios and fine structure of these two polymers determine the starch...

2019年6月26日 · It is generally accepted that starch comprises highly branched amylopectins (AP) and linear amyloses (AM). The molecular structures of AM and AP in starch granules are of crucial importance for understanding the relationship among starch biosynthesis, structure and functional properties.

Amylose possesses a linear structure with α1-4 glycosidic linkage while amylopectin possesses a branched structure with α1-4 as well as α1-6 glycosidic linkages (Figure 1) [16,17]....

2020年12月1日 · Starch fine molecular structures are of essentially important in determining its pasting and retrogradation properties. In this study, 10 different starches from various botanical sources were selected to investigate the combined action of amylose and amylopectin molecules in determining the starch …
