Exploring the Versatile Applications of Almond Gum Through Crosslinking Reactions: A Comprehensive Review
Abstract
Almond gum, a natural polysaccharide obtained from the exudate of Prunus dulcis, is drawing considerable interest due to its inherent biodegradability, biocompatibility, and multifunctional characteristics. As a plant-derived polymer, it offers a sustainable and eco-friendly alternative to synthetic materials in a variety of applications. This review highlights the growing utility of almond gum, particularly focusing on its crosslinking behavior using different agents such as glutaraldehyde, carbodiimides, gelatin, sodium caseinate, polyacrylic acid, and periodate-oxidized sugars. These crosslinking agents significantly enhance the mechanical strength, thermal stability, and water resistance of almond gum-based materials, making them more durable and suitable for practical uses. Such chemically modified forms of almond gum are increasingly used in the pharmaceutical and biomedical sectors, as well as in food processing and environmental applications. Furthermore, the development of polyelectrolyte complexes involving almond gum has opened up promising avenues in advanced drug delivery systems, tissue engineering frameworks, and water purification technologies. These complexes improve the functional versatility of almond gum, allowing it to serve as a carrier, stabilizer, or scaffold in various formulations. Modern research supports the wide-ranging potential of almond gum across disciplines including medicine, agriculture, environmental management, and food science. Its natural origin, combined with its functional adaptability, positions it as a smart and sustainable choice. This review consolidates current advancements and industrial prospects, emphasizing almond gum’s role as a valuable, eco-conscious material for next-generation polymer applications.
