Citric acid cross-linking of starch films
This paper shows that citric acid can cross-link starch and improve the tensile strength, thermal stability and decrease the dissolution of starch films in water and formic acid. The poor mechanical properties and water stability of starch have restricted its industrial applications. Although cross-linking is a common approach to improve the properties of starch products, current starch cross-l...
متن کاملKeratin/Polyvinyl Alcohol Blend Films Cross-Linked by Dialdehyde Starch and Their Potential Application for Drug Release
Feather keratin (FK) extracted from feathers represents a valuable source of biodegradable and biocompatible polymer. The aim of this study was the development and characterization of blended films based on FK and polyvinyl alcohol (PVA) cross-linked by dialdehyde starch (DAS) for a potential drug release application. The compatibility of FK/PVA was improved when cross-linked by DAS: the relati...
متن کاملHydration and swelling of amorphous cross-linked starch microspheres.
Hydration of cross-linked starch microspheres, commercially available as a medical device, was investigated using a multi-method approach. We found that the uptake of water is accompanied by substantial swelling and changes of the polymer structure. Sorption calorimetry provided information about thermodynamics of water sorption, revealed presence of isothermal glass transition and absence of h...
متن کاملphysicochemical properties of cross-linked wheat starch affected by l-ascorbic acid
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-1, as the permitted level in bakery products) on functional properties of cross-linked wheat starch. once the starch was treat...
متن کاملApplication of magnetized Sawdust Cross-linked by polyethyleniminefor removal Zn2+ from aqueous solution
The need to elimination heavy metal from aqueous solutions cannot be over emphasized.Very studies have investigated the removal heavy metal from water. In this study a new magnetic nanocomposite of PEI on magnetized Sawdust (SD/MNP/PEI) was prepared. Investigations were conducted to study the adsorption behavior of heavy metal Zn (II) on the SD/MNP/PEI nanocomposite in aqueous medium by varying...
