Oyster Mushrooms

The extraction of fungal chitosan is achieved by mild alkaline and acidic treatments as compared with the harsh chemical method used in the extraction of crustacean chitosan. In addition, fungi have a lower level of calcium carbonate compared to crustacean waste, and thus no demineralization treatment is required during processing. Fungi can be cultivated throughout the year, unlike crustacean shell supply which is dependent on the seafood industry. Mushrooms have lower levels of inorganic materials compared with crustacean shells. Fungal chitosan production can be performed in reactors with all automated and controlled conditions which makes product quality more consistent than chitosan obtained from shellfish waste.

• Animal free (vegan)
• Extremely low heavy metals
• Free of tropomyosin, the allergenic crustacean protein
• Customization of the degree of deacetylation (DD%) & molecular weight is easy
• Quality is homogeneous from one batch to another

What about the dispersity and batch-to-batch consistency over time?

Because the fungal chitosan Deacetylation degree is routinely over 98% we know that chitosan with higher DD% possesses more positively charged amine groups which is a critical point for many applications. Moreover, the chitosan obtained from fungal sources possesses superior physico-chemical characteristics. It can be tailored with predefined properties for various specialty applications, such as in biomedicines, by carefully manipulating the growth medium, the fermentation process, and the extraction parameters.
