متن کاملGrewia Gum 1: Some Mechanical and Swelling Properties of Compact and Film
Purpose: To study the mechanical and dynamic swelling properties of grewia gum, evaluate its compression behaviour and determine the effect of drying methods on its properties. Methods: Compacts (500 mg) of both freeze-dried and air-dried grewia gum were separately prepared by compression on a potassium bromide (KBr) press at different pressures and subjected to Heckel analysis. Swelling studie...
متن کاملGrewia Gum 2: Mucoadhesive Properties of Compacts and Gels
Purpose: To compare the mucoadhesive performance of grewia polysaccharide gum with those of guar gum, carboxymethylcellulose, hydroxypropyl methylcellulose and carbopol 971P. Methods: Grewia polysaccharide gum compacts or gels as well as those of guar gum, carboxymethylcellulose, hydroxypropyl methylcellulose or carbopol 971P were prepared. Texturometric and tensile analysis of the polymer gels...
متن کاملStarch-free grewia gum matrices: Compaction, swelling, erosion and drug release behaviour.
Polysaccharides are suitable for application as hydrophilic matrices because of their ability to hydrate and swell upon contact with fluids, forming a gel layer which controls drug release. When extracted from plants, polysaccharides often contain significant quantities of starch that impacts upon their functional properties. This study aimed to evaluate differences in swelling, erosion and dru...
متن کاملRheological properties of lesquerella gum fractions recovered by aqueous extraction
Lesquerella fendleri seeds contain a cross-linked carbohydrate gum with viscoelastic properties that may be used for industrial and edible applications. Laboratory studies compared the rheological behavior of gum isolates obtained from whole seed, defatted hull, and defatted meal fractions. Gum yields and rheological properties were determined for gum isolates from each of these fractions. All ...
