What is Oyster Mushroom Chitosan Oligosaccharide?
Oyster Mushroom Chitosan Oligosaccharide, as one derivative of chitosan produced by enzymatic hydrolysis,  is a low-molecular-weight, plant-derived biopolymer, specifically designed with a molecular weight of ≤ 5kDa.

Derived from Pleurotus ostreatus (oyster mushrooms), this oligosaccharide offers superior solubility and bioavailability, making it highly effective for various applications, particularly in health, agriculture, cosmetics and food industries.

Chitosan Oligosaccharide is a low molecular weight derivative of chitosan, which consists of a series of D-glucosamine units linked by β-(1→4) glycosidic bonds. It retains the beneficial properties of chitosan, such as biodegradability, biocompatibility, and antimicrobial activity, but with enhanced solubility and absorption due to its shorter polymer chains.

CAS Number: CAS No.: 148411-57-8

Chemical Structure:

• Chemical Formula: (C6H11NO4)n(C_6H_{11}NO_4)_n(C6​H11​NO4​)n​, where $n$ represents the number of glucosamine units in the oligosaccharide.
• The structure of chitosan oligosaccharide consists of a chain of D-glucosamine (GlcN) units, which can vary in length (degree of polymerization). The repeating units are linked by β-(1→4) bonds.

The typical structure can be visualized as:

• [–(C_8H_{13}NO_5)–]n
  Where “n” represents the number of repeating units. The degree of polymerization in chitosan oligosaccharides is much lower compared to high-molecular-weight chitosan, resulting in a smaller, more soluble molecule.

This structure allows for enhanced solubility in water and more efficient biological activity, making it suitable for applications such as dietary supplements, pharmaceuticals, and agriculture.

Specification

Flowchart
Our production process involves dissolving chitosan in acetic acid, followed by enzymatic hydrolysis, filtration, drying, sieving, and final testing to ensure the highest quality of chitosan oligosaccharide.

The flowchart of oyster mushroom chitosan illustrates the process of producing chitosan and its derivatives from mushroom material. Here’s a summary of the key content:

1. Starting Material: The process begins with mushroom material as the source.
2. Filtration: The mushroom material undergoes a filtration process.
3. Protein Removal: Proteins are then removed from the filtered material using an alkali solution.
4. Ash Removal: Ash content is subsequently removed with acid.
5. Chitin Extraction:
   • Acid is added without bubbles to proceed to the next stage.
   • Chitin is extracted, which is not soluble in acid.
   • An acetylation step removes the acetyl groups from the chitin using sodium hydroxide (NaOH), converting it into chitosan, which is soluble in acid.
6. Drying: The acid-soluble chitosan is then dried to produce the final mushroom chitosan product, showcased as a white powder.
7. Chitosan Derivatives: Parallel to the drying process, there is a branch leading to the production of various chitosan derivatives:
   • Chitosan Hydrochloride: Chitosan converted into its hydrochloride form.
   • Enzyme Hydrolysis: Produces chitosan oligosaccharide through enzymatic hydrolysis.
   • Carboxymethyl Chitosan: Derived through the carboxymethylation of chitosan.

The flowchart depicts a methodical approach to converting mushroom material into various forms of chitosan, focusing on the purification and chemical modification steps necessary to achieve different chitosan-based products for use in various applications.

Here are simplified descriptions of the flowcharts for Chitosan Oligosaccharide:

Chitosan Oligosaccharide Production:

• Step 1: Chitosan is dissolved in acetic acid to form a solution.
• Step 2: Enzymatic hydrolysis is applied, followed by degradation.
• Step 3: The solution undergoes filtration and precipitation.
• Step 4: The product is dried, sieved, and tested.
• Result: Chitosan Oligosaccharide.
