Latest Patents

Niekraszewicz's latest patents include innovative methods for producing modified microcrystalline chitosan. One patent discloses methods where chitosan in aqueous solution is degraded enzymatically, hydrolytically, or oxidatively. The chitosan solution is then alkalized with agitation using aqueous hydroxides and/or their salts to achieve a pH not lower than 7.0. The resulting precipitated modified microcrystalline chitosan is highly pure and can be concentrated and dried using known methods. Another patent details a process for preparing chitosan particles, where dissolved chitosan is precipitated from an acid solution through the step-wise addition of a neutralizing agent. This process results in a gel-like suspension of discrete chitosan particles, which are particularly useful in plant care.
