Chitosan oligosaccharides are derived from chitosan, a biopolymer obtained from chitin, which is found in the shells of crustaceans. These oligosaccharides are recognized for their unique properties, including biocompatibility, biodegradability, and non-toxicity, making them highly valuable in various applications. They are widely used in the food industry as natural preservatives and functional ingredients due to their ability to enhance food safety and quality. Additionally, their antioxidant and antimicrobial properties make them suitable for use in pharmaceuticals and nutraceuticals, where they can aid in drug delivery systems and support immune health.

In agriculture, chitosan oligosaccharides have gained attention for their role in promoting plant growth and enhancing resistance to pathogens, thus contributing to sustainable farming practices. Their versatility extends to cosmetics, where they are utilized for their moisturizing and skin-repairing properties. With a growing interest in natural and eco-friendly products, chitosan oligosaccharides present a compelling option for researchers and industry professionals seeking innovative solutions across multiple sectors.
