Matrix, Larvae, Hermetia illucens L, Extraction, PolysaccharideAbstract
The main sources of the polysaccharide chitin are crustacean shells generated as waste from fishing activities. However, the extraction of chitin by this methodology is highly expensive and polluting process. In order, to minimize the use of chemical agents the present work had as main objective to seek new matrices for chitin extraction, which allow methodologies that uses eco-friendly chemical agents. The chosen matrix was the larvae of the Hermetia Illucens L. and the process for extracting the polysaccharide was designed taking into account the physical property of chitin to be soluble in a warm aqueous system. The methodology followed with the extraction of oil from the larvae of H. Illucens through maceration with dichloromethane and later the larvae were subjected to hot extraction in an autoclave with controlled pressure and temperature, with water as solvent. The aqueous extract was cooled, and ethanol cool was added, which favored the precipitation of the polysaccharide. The polysaccharide was evaluated by FTIR and NMR and by comparing the data in the literature, it is concluded that the proposed methodology was efficient to extract γ-chitin.
