Adsorptive decolorization of methylene blue by crosslinked porous starch
Carbohydrate Polymers, 2013Crosslinked porous starch (CPS) was prepared by two steps. Native starch was crosslinked with epichlorohydrin and then CPS was prepared by hydrolyzing the crosslinked starch with α-amylase. As a biodegradable and safe adsorbent, CPS was used to remove methylene blue (MB) from the aqueous solution based on its characterizations, including surface area ...

Modified Starch Highly Porous Materials
Key Engineering Materials, 2021A technique for starch modification by graft polymerization of acrylamide has been developed. The obtained copolymer is soluble in a wide range of pH 2 - 12. The modification of starch made it possible to freely combine it with aqueous acid solutions of chitosan, in order to achieve a synergistic effect of their properties.

Preparation and characterization of crosslinked porous starch hemostatic
International Journal of Biological Macromolecules, 2020In order to develop starch hemostatic materials with excellent hemostatic properties, the preparation of crosslinked porous starch (SPS) with sodium trimetaphosphate (STMP) as cross-linking agent was studied in this paper. When the solid-liquid ratio of porous starch (PS) was 30%, the mass ratio of cross-linking agent to starch was 0.04-1, and the SPS ...

Naproxen Particle Design Using Porous Starch
Drug Development and Industrial Pharmacy, 2001Naproxen (Nap) was embedded in porous starch by preferential grinding, and we examined the physicochemical properties of these particles, including pore diameter, pore volume, and dissolution of naproxen. Porous starch (PS) particles made by preferential grinding with a Mechanofusion system had a higher content of naproxen than those made using the ...

Encapsulation of Plant Oils in Porous Starch Microspheres
Journal of Agricultural and Food Chemistry, 2010Natural plant products such as essential oils have gained interest for use in pest control in place of synthetic pesticides because of their low environmental impact. Essential oils can be effective in controlling parasitic mites that infest honeybee colonies, but effective encapsulants are needed to provide a sustained and targeted delivery that ...

Immobilization of urease on dialdehyde porous starch
Starch - Stärke, 2010AbstractDialdehyde porous starch (DPS) was prepared by enzymatic hydrolysis and periodate oxidation. Urease was immobilized on DPS by several techniques including physical adsorption and covalent bonding. Optimum urease immobilization conditions for maximum enzyme activity were shown as following: immobilization pH 6.0, processing time of ...

Porous Starch and Its Applications
2018Porous starches are important modified starches and are now attracting considerable attention due to their great adsorption ability. These starches contain abundant pores from the surface to the center of the granules, which increase the specific surface area, and are excellent natural absorbents.

Modification methods toward the production of porous starch: a review
Critical Reviews in Food Science and Nutrition, 2020Starch is a complex carbohydrate formed by the repeating units of glucose structure connected by the alpha-glycosidic linkages. Starch is classified according to their derivatives such as cereals, legumes, tubers, palms, fruits, and stems. For decades, native starch has been widely utilized in various applications such as a thickener, stabilizer ...

Adsorption of Modified Starches on Porous Glass
Langmuir, 2003The adsorption of cationic starch and nonionic hydroxyethyl ether starch on porous glass was investigated, for pore sizes in the range 7−222 nm. Well-dissolved cationic starch and the lower-molecular-weight hydroxyethyl ether starch both penetrate pores.
