A method to refine corn produces highly pure corn protein isolate (CPI) and intact granular starches (CPI starch). The CPI starch is superior to other commercial starches because of its intact membrane. This paper reports on the effectiveness of the CPI starch in laundering applications by comparison with a commercial starch and polyvinyl alcohol (PVA). Influence of the different starch materia...

• The process of starch assimilation in the ruminant is complex and remains an avenue by which increases in production efficiency can be gained. • Ruminal starch digestion is typically 75 to 80% of starch intake. Starch that escapes fermentation and flows to the small intestine may be more resistant to enzymatic digestion. On average, 35 to 60% of starch entering the small intestine is degraded...

Novel starch solutions were prepared by dissolving starch in NaOH/ thiourea/ urea aqueous solution, and they were further used as a surface sizing agent at high solids content in papermaking to improve the surface strength of papers. Two methods were adopted to dissolve the starch. In method A dry starch granules were directly added into the prepared solution. In method B a starch slurry was mi...

Two starch granule-bound proteins (SGP), SGP-140 and SGP-145, were preferentially associated with A-type starch granules (>10 microm) in developing and mature wheat (Triticum aestivum) kernels. Immunoblotting and N-terminal sequencing suggested that the two proteins were different variants of SBEIc, a 152-kD isoform of wheat starch-branching enzyme. Both SGP-140 and SGP-145 were localized to th...

Starch graft copolymers are expected to become increasingly important as industrial and consumer chemicals in a large variety of end uses. Therefore, a quick and accurate analytical characterization of the graft copolymer is desirable. Vinyl side chains from starch-vinyl graft copolymers have preViously been isolated by several methods. Brockway (1) hydrolyzed the starch moiety with 1 N HCl at ...

In this work, we report the effect of biopolymers (starch and gelatin) on in vitro biocompatibility property of nano hydroxyapatite (nHAp) composites. Cell culture and MTT assays were performed for in vitro biocompatibility. They show that nHAp can affect the proliferation of cells and the nHAp-starch and nHAP-gelatin biocomposites have no negative effect on the cell morphology, viability and p...

In regions of their leaves, tdy1-R mutants hyperaccumulate starch. We propose 2 alternative hypotheses to account for the data, that Tdy1 functions in starch catabolism or that Tdy1 promotes sucrose export from leaves. To determine whether Tdy1 might function in starch breakdown, we exposed plants to extended darkness. We found that the tdy1-R mutant leaves retain large amounts of starch on pro...

Corn starch showed higher fresh paste consistency than wheat starch, and, after aging 24 hr, its gels were more firm at 6% solids or less. Between 7 and 30% solids, gels of wheat starch were more firm than those of corn starch. The lipids in wheat and corn starches were reduced 88-97% by boiling three times in four parts of a 3:1 (v/v) mixture of ethanol/water. Iodine-binding capacity of corn a...

Using a sedimentation method, the extracted starch from Dioscorea hispida tuber was characterized for their morphological, thermal and other physicochemical properties such as total starch content, moisture content, pH, water binding capacity (WBC), solubility and swelling power. The starch content extracted from the tuber was 11.46% with the WBC and moisture content were 107% and 249% respecti...

Starch is a carbohydrate composed of chain of glucose molecule. Potato, corn, rice are the major sources for starch but they are also used as a food. Our aim was to extract starch from some nonconventional source like taro plant (Colocasia esculenta) and did some physical and chemical modification to enhance the properties of starch. Physical modification method of starch like Osmotic Pressure ...
