2022年12月1日 · The successful incorporation of gel beads into the human food system requires an in-depth understanding of beads' production, properties, release, or dissociation mechanisms at different targeted sites. This review has pointed out the latest developments and achievements in hydrogel beads from micro to millimeter-scale in the food industry.

2020年6月1日 · This review first provides an overview of traditionally used and recently developed methods for preparation and modification of chitosan-based hydrogel beads, and then discusses the advances in the most recent five years in their applications for delivery of food bioactive compounds and treatment of agricultural recycled wastewater.

2021年12月25日 · Biopolymer-based hydrogel beads possessing intrinsic low-toxicity, biocompatibility and biodegradability have gained widespread utility in several applications. Among the biopolymers, cellulose is one of the most abundant renewable biomaterials.

2024年9月12日 · We intended to formulate chitosan-coated pectin beads for use in delaying premature release of the encapsulate under gastric conditions but allowing release through disintegration under intestinal conditions. The latter is of utmost importance in delivering most functional food ingredients.

Hydrogel products constitute a group of polymeric materials, the hydrophilic structure of which renders them capable of holding large amounts of water in their three-dimensional networks. Extensive employment of these products in a number of industrial and environmental areas of application is considered to be of prime importance.

2022年8月30日 · Amidoxime hydrogel beads of modified alginate and amidoximated synthetic polymers have been successfully synthesized and used as sorbents for dyes, showing selective adsorption towards cationic dyes in the presence of anionic/cationic mixed dyes [31].

2023年8月5日 · Blended biopolymer-based photocatalytic hydrogel beads were synthesized by dissolving the biopolymers in 1-ethyl-3-methylimidazolium acetate ( [Emim] [Ac]), adding TiO 2, and reconstituting the beads with ethanol. The incorporation of modifying biopolymer significantly enhanced the adsorption capacity of the cellulose/TiO 2 beads.

2020年6月1日 · With three types of reactive functional groups, one amino group and both primary and secondary hydroxyl groups, chitosan has been used as a popular biomaterial for synthesis of three-dimensional and flexible hydrogel beads that swell in water and biological fluids.

2018年11月9日 · In this study, sodium alginate was employed as a starting material for preparing two kinds of biocompatible adsorbents, including calcium alginate hydrogel beads and magnetic hydrogel beads.

2020年12月18日 · Hydrogels beads are three-dimensional, cross-linked networks of hydrophilic polymers formed in spherical shape and sized in the range of 0.5–1.0 mm of diameter. Beads are formed by various cross-linking methods such as chemical and irradiation methods.
