WebThe most important functional difference between these forms is that ISA generally acts upon phytoglycogen and amylopectin by hydrolysing the α-1,6-linkages of polyglucans, which play impor- tant roles in the modification of excessively branched chains or the removal of improper branches of amylopectin formed by branching enzymes to … Web18 de jan. de 2024 · The aim of this study was to determine the fine structure of amylopectin of waxy maize starch, which has been widely used in industry for producing modified starch, such as the esterification with octenyl succinic anhydride. Findings. Waxy maize starch was hydrolyzed with α-amylase for 3.5 hr to obtain structural clusters.
WebSince the 1940 s, many scientists have attempted to elucidate the distinct structure of amylopectin. One of the most accepted concepts is that amylopectin has a structural … Web18 de jan. de 2010 · The sizes of the clusters in the form of beta-limit dextrins were uniform with an average degree of polymerization of 67-78. The distribution profiles of B-chains were similar in all cluster fractions, which suggested that the internal structure of the cassava amylopectin clusters was homogenous.
Web27 de mar. de 2024 · The branched cluster forms the crystalline lamella while the helical cluster forms the amorphous lamella, with about 9 nm of distance between each other (Ball et al., 1996). The width of crystalline and amorphous lamella represents the length of an amylopectin cluster (Schirmer et al., 2013).
Web12 de set. de 2013 · The clusters in the whole starch were produced by partial hydrolysis using α-amylase of Bacillus amyloliquefaciens, and were subsequently treated with β-amylase to remove the linear amylose and to produce β-limit dextrins of clusters from amylopectin.
