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...

Mung bean starches were subjected to heat-moisture treatment (HMT) by different moisture contents (15%, 20%, 25%, 30% and 35%) at 120°C for 12h. The impact on the yields of resistant starch (RS), microstructure, physicochemical and functional properties was investigated. Compared to native starch, the RS content of heat-moisture treated starches increased significantly. The RS level of HMT-20 w...

Modified starch was prepared in this work by acid-thinning and oxidizing corn starch with ammonium persulfate. Also, starch-based aqueous polymer isocyanate (API) wood adhesive was prepared. The effect of the added amount of modified starch, styrene butadiene rubber (SBR), polymeric diphenylmethane diisocyanate (P-MDI), and the mass concentration of polyvinyl alcohol (PVOH) on the bonding stren...

In this study, modified starch was used as a fat replacer in the milk. The fat replacer was manufactured from modified starch such as pre-gelatinized and cross–linked starches. Modified starches were manufactured by hydrochloric acid and citric acid treatments from potato and wheat and were added to skim milk at concentrations of 0.15%, 0.30% and 0.45%. Viscosity, total solid, fat content, titr...
