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 ...

Corn starch particles are used as a surgical glove lubricant. At present there is no better alternative for this lubricant. Implantation of corn starch particles into the peritoneal cavity can induce foreign body reactions, starch peritonitis and starch granulomata, and may cause adhesions and intestinal obstruction. Starch peritonitis should be treated conservatively.

Effects of addition of alum (0.00 -1.0% w/w) on pasting and some physicochemical characteristics of cassava starch were investigated with view to evaluate the potential of alum as a cassava starch modifying agent. The modified starch was prepared by pre-treatment of the native starch with alkaline at room temperature prior to modification using alum. Alum modified cassava starch were characteri...

I. Eighty weanling albino rats, five from each of sixteen litters were distributed between five dietary groups in sixteen randomized blocks. Each block was formed from within a litter and each animal in the block received a different diet. 2. The main features of the diets were: group I , 72% sucrose; group 2, 72% uncooked wheat starch; group 3, 72% roll-dried wheat starch; group 4, 3 6 % sucro...

Purpose: To optimize the process conditions and analyze in vitro digestibility of corn starch phosphodiester prepared by sodium trimetaphosphate (STMP). Methods: By using response surface method, the effects of STMP concentration, pH, esterification temperature, and urea addition on digestion resistance of corn starch phosphodiester were investigated and optimal conditions were determined. Corn...

Starch retrogradation is a term used to define the process in which gelatinized starch undergoes a disorder-to-order transition. A thorough understanding of starch retrogradation behavior plays an important role in maintaining the quality of starchy foods during storage. By means of DSC, we have demonstrated for the first time that at low water contents, the enthalpy change of retrograded starc...

Starch content in leaves of HLB (Huanglongbing or citrus greening)-affected branches increases sharply compared to those from non-HLB trees. Starch not only over-accumulates in photosynthetic cells, but starch grains become prominent in vascular parenchyma and sieve elements as well. These observations imply strong disturbances in starch metabolism and photoassimilate partitioning in HLB-affect...

BACKGROUND Starch-binding domains from carbohydrate binding module family 20 have been used as a tool for starch engineering. Previous studies showed that expression of starch binding domain fusion proteins in planta resulted in modified starch granule structures and physicochemical properties. However, although 13 carbohydrate binding module families have been reported to contain starch-bindin...

(Sorghum Bicolor (L.) Moench) on in vitro starch digestibility and α-amylase activity Authors: N.L. Mkandawire, R.C. Kaufman, S.R. Bean, C.L. Weller, D.S. Jackson, D.J. Rose Submitted to: Journal of Agricultural & Food Chemistry Recently, the effects of sorghum tannins on starch digestibility in humans have been of interest, since tanins may inhibit starch digestion and contribute to reducing g...

The properties of blends of polycaprolactone and starch (PCL/starch) and maleic anhydride (MAH)-grafted-polycaprolactone and starch (PCL-g-MAH/starch) were examined using Fourier transform infrared (FTIR) spectroscopy, H nuclear magnetic resonance (H NMR), differential scanning calorimetry (DSC), and mechanical testing. Mechanical and thermal properties of PCL became noticeably worse when it wa...
