What is Acid-Soluble Oyster Mushroom Chitosan?
Acid-Soluble Oyster Mushroom Chitosan is a versatile, plant-based biopolymer derived from Pleurotus ostreatus (oyster mushrooms).

Unlike traditional chitosan sourced from crustaceans, this vegetal chitosan offers exceptional purity and is ideal for applications requiring solubility in acidic environments. Its unique properties make it an excellent choice for various industrial and health-related uses.

Chemically, chitosan is a linear polysaccharide composed of randomly distributed β-(1→4)-linked D-glucosamine and N-acetyl-D-glucosamine units. The chemical formula of chitosan is typically represented as (C6H11NO4)n(C_6H_{11}NO_4)_n(C6​H11​NO4​)n​, where $n$ indicates the degree of polymerization. The CAS (Chemical Abstracts Service) number for chitosan is 9012-76-4.

Specification

• Appearance: Off-white to light yellow powder
• Degree of Deacetylation: ≥ 85% (typically ≥98%)
• Molecular Weight: 20,000 – 1,500,000 Da
• Viscosity: 20-1000 mPa.s (customizable) (typical 20cps, 100cps, 200cps, 400cps, 600cps, 800cps, 1000cps)
• Moisture Content: ≤ 10%
• Ash Content: ≤ 1.5%
• Solubility: Soluble in dilute acids (e.g., acetic acid)

This table illustrates a direct correlation between the viscosity and molecular weight of chitosan, where higher molecular weights result in increased viscosity. This relationship is crucial for selecting the appropriate chitosan grade for various applications, as higher viscosity chitosan, due to its larger molecular structure, is ideal for creating thicker gels and films.

Additionally, the degree of deacetylation influences this relationship, further refining the material’s suitability for specific industrial uses.

Solubility
This chitosan is specially formulated to dissolve easily in dilute acidic solutions, typically at a 1% solubility ratio, making it ideal for applications requiring a stable, acid-soluble polymer. Its high solubility ensures efficient performance in various formulations.

Flowchart
The production process of Oyster Mushroom Chitosan follows stringent quality controls, ensuring the highest purity and efficacy. From the initial extraction to final processing, each step is meticulously monitored.

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.
