Introduction:
Chitosan is a linear polysaccharide composed of randomly distributed β-(1-4)-linked D-glucosamine (deacetylated unit) and N-acetyl-D
-glucosamine (acetylated unit). It is made by treating shrimp and other crustacean shells with the alkali.
Chitosan has a number of commercial and possible biomedical uses. It can be used in agriculture as a seed treatment and biopesticide,
helping plants to fight off fungal infections. In winemaking it can be used as a fining agent, also helping to prevent spoilage. In industry,
it can be used in a self-healing polyurethane paint coating. In medicine, it may be useful in bandages to reduce bleeding, and as an
antibacterial agent; it can also be used to help deliver drugs through the skin.
More controversially, chitosan has been asserted to have used in limiting fat absorption, which would make it useful for dieting, but there
is evidence against this. Other uses of chitosan that have been researched include use as a soluble dietary fiber.
Application:
1. Agricultural use
In agriculture, chitosan powder is used primarily as a natural seed treatment and plant growth enhancer, and as an ecologically friendly
biopesticide substance that boosts the innate ability of plants to defend themselves against fungal infections. The natural biocontrol active
ingredients, chitin/chitosan, are found in the shells of crustaceans, such as lobsters, crabs, and shrimp, and many other organisms, including
insects and fungi. It is one of the most abundant biodegradable materials in the world.
2. Water filtration
Chitosan powder can also be used in water processing engineering as a part of a filtration process. Chitosan powder causes the fine sediment
particles to bind together and is subsequently removed with the sediment during sand filtration. It also removes phosphorus, heavy minerals,
and oils from the water. Chitosan is an important additive in the filtration process. Sand filtration apparently can remove up to 50% of the turbidity
alone, while the chitosan with sand filtration removes up to 99% turbidity. Chitosan has been used to precipitate caseins from bovine milk and
cheese making.
3. Winemaking & fungal source Chitosan
Chitosan has a long history of use as a fining agent in winemaking. Fungal source Chitosan has shown an increase in settling activity, reduction
of oxidized polyphenolics in juice and wine as well as the chelation and removal of copper (post-racking). Fungal-source Chitosan can also be
used in winemaking for the control of the spoilage yeast Brettanomyces. These products and uses are approved for European use by the EU
and OIV standards.
