Acid-Soluble Aspergillus Niger Chitosan – High-Quality Fungal-Derived Chitosan

What is Acid-Soluble Aspergillus Niger Chitosan?
Acid-Soluble Aspergillus Niger Chitosan is a specialized form of chitosan derived from the fungal species Aspergillus niger.

This variant is designed to be highly soluble in acidic solutions, making it an ideal ingredient for various industrial applications where solubility and bioactivity are crucial. It serves as an excellent alternative to traditional chitosan derived from crustaceans, particularly for those seeking a vegan, non-allergenic option.

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 Acid-Soluble Aspergillus Niger Chitosan involves the extraction and purification of chitosan, followed by a series of steps to ensure high solubility and optimal performance, including dissolving, filtering, and drying.

The flowchart of aspergillus niger chitosan outlines the process for extracting chitosan from Aspergillus niger, a type of fungus. Here’s a step-by-step summary of the key points:

1. Starting Material: Aspergillus niger is cultured through a fermentation process using corn.
2. Extraction:
   • The fungal biomass undergoes a bulk flocculation.
   • This is followed by centrifugation to separate the components.
   • The pH of the resulting material is adjusted to alkaline conditions (pH 8-10).
   • Another round of centrifugation and isolation occurs.
   • The pH is adjusted back to neutral (pH 7), and the sediment is washed and precipitated.
   • The sediment is then extracted with 5% acetic acid at 100°C for five hours to get the clear solution.
   • It is washed again to achieve a clear solution with a neutral pH.
3. Chitin Production:
   • The clear solution is treated with 7% sodium hydroxide (NaOH) at a ratio of 1:10 (W/V) at 50°C for three hours.
   • Centrifugal washing follows, resulting in the production of chitin as a clear solution to get the sediment.
4. Deacetylation:
   • The sediment undergoes the deacetylation process. It’s treated with 20% NaOH at a ratio of 1:10 (W/V) and heated in a microwave at 480W for 15 minutes.
   • This step is crucial to convert chitin into chitosan by removing acetyl groups.
5. Final Steps:
   • The final sediment, which is now deacetylated chitin or chitosan, is extracted.
   • It undergoes drying, followed by sieving to achieve the desired particle size.
6. End Product: The final product is solid Aspergillus niger chitosan.

This process includes several steps involving pH adjustment, centrifugation, chemical treatments, and heating, which are critical to ensuring the purity and quality of the chitosan extracted from Aspergillus niger.
