Starch is a polymer of glucose molecules and consists of two kinds of polymers -- amylose which is a straight chain, and amylopectin
, which is branched.
Of total dry matter about 60-80% is starch in the form of amylose and amylopectin
Plantic corn starch has -75% amylose/-25% amylopectin
while traditional corn starch is closer to 20/80.
Starch, a complex carbohydrate, is composed of amylose (linear) and amylopectin
(branching) molecules (Mojsov, 2012).
Generally, starches with high relative amylose amylopectin
are more rigid and resistant to breakage than starches with lower ratio values (ROONEY & PFLUGFELDER, 1986).
The influence of the amylopectin
amylase ratio in samples of corn on the true metabolizable energy value for ducks.
4-[alpha]-glycoside linkages of amylose and amylopectin
chains, decomposing starch into soluble dextrins and oligosaccharides.
Hydrocolloids, particularly xanthan gum encouraged the formation of gel matrix and this resulted in cross-links between amylose, amylopectin
and hydrocolloid chains .
1] region in the Near infrared spectra of the [alpha], [beta] and [gamma] cyclodextrins show that the intermolecular interactions taking place between the OH groups in these molecules are relatively less in order than in the carbohydrate polymers like amylose, amylopectin
This native variety of the Chishui River basin is an organic sorghum called "red tassels", which features thick husk, small grain, red color, high content of tannin and amylopectin
, and abundant phenolic substances.
Starch mainly contains 20 to 30 percent amylase and 70 to 80 percent amylopectin
ratio was determined with a Megazyme amylose/amylopectin
assay kit (Megazyme International Ireland, Bray Business Park, Bray, Ireland) using the selective quantitative precipitation reaction of con-canavalin A (Con A) for amylopectin
(Gibson et al.
