Cereal Cheill. XO(4):427·-436 Amy lose content is closely related to wheat flour pasting or thermal properties, and thus affects final food qualities. J:iourteen flour blends with amylose content ranges of < I to 29% were used to study tortilla production and quality parameters. Reduced amylose contents decreased dough stickiness and pliability; low amylose doughs were also very smooth in appea...

We have previously found that a partially 2-deoxygenated (P2D)-amylose, produced by glucan phosphorylase (GP)-catalyzed enzymatic copolymerization, shows hydrophobic nature. Based on this finding, the present study demonstrates hydrophobization of strong hydrophilic polypeptide, i.e., poly(γ-glutamic acid) (PGA), grafting P2D-amylose chains via GP-catalyzed approach. After maltooligosaccharide ...

Barley grain starch is formed by amylose and amylopectin in a 1:3 ratio, and is packed into granules of different dimensions. The distribution of granule dimension is bimodal, with a majority of small spherical B-granules and a smaller amount of large discoidal A-granules containing the majority of the starch. Starch granules are semi-crystalline structures with characteristic X-ray diffraction...

Starch is one of the major dietary energy sources for mammals. However, the nutritional value of starch largely depends on its amylose and amylopectin ratio. In this study, the overall metabolic and transcriptomic responses of weaned pigs fed with different dietary starches were assessed. Sixteen weaned pigs were randomly allotted to two experimental diets containing either of pure cassava star...

China is the first country to use heterosis successfully for commercial rice production. This study compared the main quality characteristics (head rice rate, chalky rice rate, chalkiness degree, gel consistency, amylose content, and length-to-width ratio) of 635 rice varieties (not including upland and glutinous rice) released from 2000 to 2014 to establish the quality status and offer suggest...

Starch the main storage carbohydrate in higher plants Ta& 1. Characterjstjcs of the SBE c-NA from p a t o and is composed of the two polysaccharides, amylopectin (approximately 75%) and amylose (approximately 25%). Amylopectin is a highly branched a-1,4 glucan containing a1,6 branch points, whereas amylose is composed of long, linear a-1,4 glucans, some of which have very few a-1,6 branch point...
