Bio-degradable cassava starch-based adhesives were produced from chemically gelatinized starch formulations. The varying combinations of process parameters applied include: concentration gelatinization modifier, mass % borax/starch, and temperature reaction mixture. physico-chemical for characterizing the adhesive samples viscosity, density, pH bonding strength. effects variation on quality ass...

The normality dependence and the kinetics of flow behavior in the rice starch dispersion under strong alkali conditions were studied. Non-Newtonian flow (power-law) quantities n and μ (σ = μ(̇); σ: shear stress, ̇: shear rate) of the samples stored (gelatinized) at 20◦C for 10min after the addition of NaOH solution with the normality 0.090 0.175N, were measured by a cone-plate type rotational v...

A diet with a high glycemic index (GI) is associated with an elevated risk for obesity or type 2 diabetes. We investigated the GI of a newly-developed fiber enriched cookie and characterized the microstructure of ingredients used. In a study with 26 non-diabetic healthy volunteers it was shown that the fiber enriched cookie has a GI of 58.9 in relation to white bread as reference. Using a conve...

The physical attributes, chemical composition, and physicochemical properties of 2 medium-grain rice cultivars from Arkansas (Bengal, Medark) and from California (M202, M204) were compared when grown in their respective locations and grown together in Arkansas to better understand the impacts of heredity and environment on medium-grain rice quality. Variations existed in grain dimensions, parti...

Enhancement of product properties of extruded starch based products can be achieved by incorporating health promoting oil into the matrix. In order to achieve a preferably high expansion with a homogeneous pore structure, the expansion mechanisms have to be understood. In our study, we applied a customized twin-screw extruder set up to feed medium-chain triglycerides after complete gelatinizati...

Background: A combination of heat-moisture treatment and citric acid was used to modify pearl millet starch in this study. Changes structural, thermal vitro digestibility the treated starches were investigated. Methods: Native isolated using alkaline steeping method. dual modified (Heat moisture acid) for further analysis. To examine granular morphology SEM, DSC, RC assay assessed quantify prop...

The response surface method (RSM) has an important application in formulation of new products. This study determined the effect electric hot-air drying on functional properties flour made from orange-fleshed sweet potato (OFSP). Flour cultivars Bophelo (B) and Impilo (IM) were treated with 13 temperature-time combinations designed by STAT EASE software version 8.01.0. dried at 70 °C for 8.6 hrs...
