The purpose of this study was to investigate the effects of tannins on starch digestion in tannin-containing sorghum extracts and wholegrain flours from 12 sorghum varieties. Extracts reduced amylase activity in a tannin concentration-dependent manner when the extract was mixed with the enzyme before substrate (amylopectin) addition, with higher molecular weight tannins showing greater reductio...

The effect of amylose content on digestibility of starch in the small intestine and on the concentration of plasma lipid were studied in ileorectostomized rats and in ovariectomized rats, respectively. Seven kinds of starch with different amylose content (0, 27, 54, 62, 76, 79, 86 %) were used as test starch, which contained 0.4, 5.6, 37.1, 40.2, 45.6, 36.9 and 36.1 % resistant starch (RS), res...

pasting is one of the most important properties of wheat starch determining the flour quality and functionality. twenty three new plant type (npt) wheat derivatives along with three checks (pbw 343, hd 2329, and raj 3765) have been studied in multi-location trials to assess the variation and environment induced fluctuations for their starch pasting properties. although all flour pasting charact...

in this study, the usage of starch as adhesives in packaging industry and improving the properties of starch on the development of its applications have been discussed. starch is widely used in various industries, but in the celluloses packaging industry it can be just used as a coating binder, sizing agent or adhesive industries. in these industries, high print quality, low water absorption an...

the starch based films have some disadvantages such as weak mechanical and poor water barrier properties that restrict their applications in food packaging. in the present research, the polyvinyl alcohol (povh), as a compatible polymer, and montmorillonite (mmt) nanoclay, as a nanofiller, were added to plasticized starch film (ps) to improve its properties and also to produce ps-mmt-pvoh nanoco...

Objective(s):The aim of this study was to improve flowability and compressibility characteristics of starch to use as a suitable excipient in direct compression tabletting. Quasi-emulsion solvent diffusion was used as a crystal modification method. Materials and Methods: Corn starch was dissolved in hydrochloric acid at 80˚C and then ethanol as a non-solvent was added with lowering temperature ...
