Hydrogels based on a graft copolymer of acrylic acid (AA) and acrylamide (AAm) backbone starch, obtained from different natural sources, have been prepared characterized for potential agricultural use, as soil moisture regulators nutrient sources plant nutrition. Five types starch are used: corn, waxy wheat, potato, rice starch. by solution polymerization method, in the presence ammonium persul...

Culinary cassava (Manihot esculenta L.) qualities that make a variety popular are a function of starch physicochemical properties. Hence, in response to inferior root qualities in some released cassava varieties in Uganda compared to the local germplasm, a study was undertaken to examine: (i) starch physicochemical characteristics in both introduced and local varieties; and (ii) the variation i...

Abstract Ariid catfish is a demersal fish species with high production rate. Fishbone by-product protein content converted into gelatin. Gelatin can be utilized as an edible film due to its low water resistance and tensile strength so that suitable polymer needed form good film, namely chitosan tapioca starch. This study aimed determine the effect of on characteristics best formulation ariid bo...

Starch is one of the most used polysaccharides in formulation Edible Films (EFs). This work aimed to develop starch-based EFs employing extrusion technology as a pretreatment casting technique and evaluate storage relative humidity (RH) effect determine their possible application food coating. Corn starch mixture plasticizers (sorbitol glycerol) were processed twin-screw extruder. The was for f...

Most recent developments in polymers from renewable resources have focused on thermoplastics, whereas there has been no comparable development of plastics with elastomeric properties. Here we evaluate the possibility of developing renewable elastomers based on starch. Potato starch plasticized with glycerol (called plasticized starch, or PLS) was melt-blended with small quantities (5 wt % or 15...

Physicochemical, morphological, rheological characteristics and finite element modelling of wheat flour, rice starch gluten were studied in this work. The physicochemical analysis flour exhibited almost similar to without present. Rice contained higher value carbohydrate fibres compared starch. Likewise, interacted strongly with water oil due absorption, solubility absorption indices SEM images...

The aim of this study is to improve the Cold Water Solubility (CWS) and esterification activity of Native corn Starch (NS) by pretreatment NS using NaOH/urea aqueous solution. The influence of pretreatment on granule shape and crystal structure of corn starch was investigated by Scanning Electron Microscopy (SEM) and X-Ray Diffraction (XRD). It has been found that the average particle size of P...

The study was based on correlating a dataset of in vivo mean starch digestibility coefficients obtained in the immediate post-weaning phase of piglets with a range of dietary in vitro variables. The paper presents a model that predicts (R2 0.71) in vivo average starch digestibility coefficients in the 0.5 small-intestinal region of newly weaned piglets fed cereal-based diets using seven in vitr...

There is some evidence on the effects of organic acids on the functional properties of native starches. However, there is little information on such effects on modified starches. The main objective of this study was to determine the effects of L-ascorbic acid (150 mg kg, as the permitted level in bakery products) on functional properties of cross-linked wheat starch. Once the starch was treated...
