Preparation and Characterization of High Amylose Corn Starch–Microcrystalline Cellulose Aerogel with High Absorption

“…Many researchers have aimed to enhance the material’s functions and provide better properties by blending cellulose with other materials such as N, N’-methylene bisacrylamide (MBA)/graphene oxide (GO) hybrid [9], N-methylol dimethylphosphonopropionamide (MDPA) and 1,2,3,4-butanetetracarboxylic acid (BTCA) [16], silica [17], and chitosan [18], etc., but most methods are quite complex. Some studies show that the blend of cellulose and starch can improve the mechanical properties [19], moisture resistance [20], and thermal stability [21] of the composites, whereas there are few reports on the preparation of cellulose aerogel by mixing starch. Compared with raw cellulose, microcrystalline cellulose has the advantage of a high specific surface area, which makes it a material with greater development potential.…”

Recent Advances in Ionic Liquids in Biomedicine

“…Starch/Cellulose gels designed for use as gastric delivery systems were synthesized by dissolving and regenerating the starting materials in imidazolium acetate ILs. [ 82 ] Bielas et al. [ 83 ] report the formation of ionic polymers via a salt‐metathesis‐based release method using salicylate‐based ionic liquids.…”

Improving the in vitro digestibility of rice starch by thermomechanically assisted complexation with guar gum

“…The MDI Jade 6.0 software was used to compute the crystallinity between 4° and 30° 2θ, according to our previous studies (Xu, Tan, Chen, Li, & Xie, 2019). The integrated areas of all crystalline peaks halo on the X-ray diffractogram was the crystallization area (A c ), and the integrated areas of the amorphous halo on the X-ray diffractogram was the amorphous region (A a ).…”
