For digestion of starch in humans, α-amylase first hydrolyzes starch molecules to produce α-limit dextrins, followed by complete hydrolysis to glucose by the mucosal α-glucosidases in the small intestine. It is known that α-1,6 linkages in starch are hydrolyzed at a lower rate than are α-1,4 linkages. Here, to create designed slowly digestible carbohydrates, the structure of waxy corn starch (W...

<p>Industrial production brings serious Cr(Ⅵ) pollution problems, so as to explore new treatment methods for Cr(Ⅵ), In this paper, modified montmorillonite was prepared by modifying with starch and lanthanum nitrate, its adsorption mechanism effect on were explored. The monundonerization properties characterized Zeta potential, X-ray diffraction (XRD), Fourier Transform infrared spectrosc...

The properties of starch have been extensively studied as starch is readily available in large quantities, biodegradable, inexpensive, and non toxic. In particular, starch has been hydrophobically modified to widen its application range. For examples, the modification of starch with fatty acid2 and butylene glycidyl ether3 has been implemented to investigate its potential use in drug delivery. ...

Extrusion cooking as an attractive process for continuous food production has been extensively developed in recent years. The high temperature–short time extrusion cooking is used in the food industry to produce direct expanded products such as snack foods, breakfast cereals and pet foods (Miller, 1990; Moore, 1994; Rokey, 1994). Extrusion of food material results in starch gelatinization, dena...

The Amflora (EH92-527-1) potato is a genetically modified (GM) potato in which only starch of the amylopectin form is produced. This has been achieved by intervening with the biosynthesis of starch in this variety of potato. The Amflora potato is solely grown for the purposes of enhancing its industrial application. Although the Amflora potato is not fit for human consumption, the presence of t...

Developing host digestion-resistant starches to promote human health is of great research interest. Chemically modified starches (CMS) are widely used in processed foods and although the modification of the starch molecule allows specific reduction in digestibility, the metabolic effects of CMS have been less well described. This short-term study evaluated the impact of enzymatically modified s...

BACKGROUND In the last year, the worldwide concern about the abuse of fossil fuels and the seeking for alternatives sources to produce energy have found microbial oils has potential candidates for diesel substitutes. Yarrowia lipolytica has emerged as a paradigm organism for the production of bio-lipids in white biotechnology. It accumulates high amounts of lipids from glucose as sole carbon so...

Glycogen synthase kinase 3 (GSK-3) was originally identified as a regulator of glycogen synthesis in mammals. Like starch in plants, glycogen is a polymer of glucose, and serves as an energy and carbon store. Starch is the main carbohydrate store in plants. Regulation of starch metabolism, in particular in response to environmental cues, is of primary importance for carbon and energy flow in pl...
