Starch is a carbohydrate or polysaccharide consisting of large number glucose units linked through glycosidic bonds and containing different amounts amylose amylopectin as macromolecules. modification can be done physically, chemically, enzymatically. The process chemical starch aims to separate the long chains from polymer molecules in order reduce high viscosity unmodified solution thus maxim...

Cassava (Manihot esculenta, Crantz) is an important food security crop, but it is becoming an important raw material for different industrial applications. Cassava is the second most important source of starch worldwide. Novel starch properties are of interest to the starch industry, and one them is the recently identified amylose-free (waxy) cassava starch. Waxy mutants have been found in diff...

cross linking of high density polyethylene (hdpe) was first performed via high energy10 mev electron beam (eb) irradiation. hdpe was also cross linked withdicumyle peroxide (dcp).the gel content of samples was determined by solvent extraction.degree of cross linking was evaluated by hot set apparatus; as well .in order to clarify the effectof nature of cross linking, correlation of electrical p...

Many plants accumulate substantial starch reserves in their leaves during the day and remobilize them at night to provide carbon and energy for maintenance and growth. In this paper, we explore the role of a sugar-signaling metabolite, trehalose-6-phosphate (Tre6P), in regulating the accumulation and turnover of transitory starch in Arabidopsis (Arabidopsis thaliana) leaves. Ethanol-induced ove...

In this study of barley starch synthesis, the interaction between mutations at the sex6 locus and the amo1 locus has been characterized. Four barley genotypes, the wild type, sex6, amo1, and the amo1sex6 double mutant, were generated by backcrossing the sex6 mutation present in Himalaya292 into the amo1 'high amylose Glacier'. The wild type, amo1, and sex6 genotypes gave starch phenotypes consi...

Various modification treatments have been carried out to improve the physicochemical and functional properties of various types starch flour. Modification by acetylation has widely used quality stability starch. This review describes effects its dual modifications on starch/flour their applications. Acetylation can increase swelling power, volume, water/oil absorption capacity, retrogradation s...

The branched glucans glycogen and starch are the most widespread storage carbohydrates in living organisms. The production of semicrystalline starch granules in plants is more complex than that of small, soluble glycogen particles in microbes and animals. However, the factors determining whether glycogen or starch is formed are not fully understood. The tropical tree Cecropia peltata is a rare ...

Starch has been an inexhaustible subject of research for many decades. It is an inexpensive, readily-available material with extensive application in the food and processing industry. Researchers are continually trying to improve its properties by different modification procedures and expand its application. What is mostly applied in this view are their chemical modifications, among which organ...
