Background: Guar gum is a water-soluble polysaccharide called galactomannan, obtained
from the endosperm of Cyamopsis tetragonolobus, a plant belonging to the Leguminosae family.
Galactomannan is a biopolymer rich in functional groups, particularly hydroxyl groups, which expands
the possibilities of its chemical modification and, therefore, biological applications.
Objective: This review aims to present and discuss various methods used in the preparation of guar
gum composites and their applications in the biomedical, pharmaceutical, food, and cosmetic industries.
Methods: The published data about the extraction procedure of guar gum and its various physicochemical
properties have been collected and analyzed. Further, the published information about various
methods used for the preparation of guar gum composite systems, including film, hydrogel, and
beads, have been gathered and comprehensively discussed in this review. The applications of guar
gum based composites in the field of biomedical, pharmaceutical, food, and cosmetics have also been
reviewed in detail.
Results: Different guar gum composite systems have shown multifunctional properties, including
gelling and emulsifying ability, thickening and binding property, quick solubility in water, good biocompatibility,
and biodegradability in the domain of biomedical, pharmaceutical, food, and cosmetic
Conclusion: Recent advancements in the preparation and applications of guar gum composites
summarized in this review will enhance the practical applications of this polymer in various industries.
