Chitosan
Chitosan is a naturally occurring polymer derived from chitin, a polysaccharide found in the exoskeletons of crustaceans, insects, fungi, bacteria and algae. It is obtained through the deacetylation of chitin, resulting in a polymer with a degree of deacetylation of 50% or more.
Properties of Chitosan
Chitosan has several unique properties, including:
1. Biocompatibility: Chitosan is biocompatible, biodegradable and non-toxic, making it suitable for various applications.
2. Antimicrobial properties: Chitosan has antimicrobial properties, making it effective against a range of microorganisms.
Applications of Chitosan
Chitosan has a wide range of applications, including:
- Water treatment: Chitosan can be used to remove impurities and contaminants from water.
- Agriculture: Chitosan can be used as a plant defense activator and growth stimulant and as a non-toxic fertilizer additive.
- Animal feed: Chitosan can be used as a feed additive for farm animals and pets to enhance growth and eliminate the need for antibiotics.
Grades of Chitosan
There are different grades of chitosan, including what we we offer from crustacean sources:
- Agricultural grade: This grade is generally created with less expenditure of materials and energy, making it more affordable ( $19-25/kilogram range). It is for the types of applications list above.
Degree of Deacetylation - Grade
The degree of deacetylation (DDA) is a crucial factor that determines the properties of chitosan. It refers to the percentage of acetyl groups removed from the chitin structure. Chitosan with a higher degree of deacetylation is more soluble in acidic solutions and has enhanced bioactivity. A higher DDA means that the chitosan will have better performance in applications requiring solubility and bioactivity, making it suitable for a wide range of industrial, cosmetic, and agricultural uses.
Molecular Weight
Molecular weight is a significant property of chitosan that influences its viscosity, solubility, and biological activity. It is usually measured in kilodaltons (kDa) and can vary widely depending on the source and preparation method of the chitosan. Higher molecular weight chitosan tends to have higher viscosity and may form gels, while lower molecular weight chitosan is more soluble and easier to process. Understanding the molecular weight of chitosan is essential for tailoring it to specific applications, such as drug delivery, food preservation, and water treatment.
Certificate of Analysis (CoA)
The Certificate of Analysis (CoA) provides detailed information about the specific batch of chitosan, including its purity, degree of deacetylation, molecular weight, and any contaminants. This document ensures that the product meets the required specifications and standards. It is essential for verifying the quality and consistency of chitosan used in various applications. For example, here is a link to the CoA for fungal source acid soluble chitosan.
