Studies on the extraction and characterization of chitin from the Peels of various waste sources


Jai Vignesh V, Stalin S, Madan Raj B, Dr. Shaleesha A Stanley

The study was envisaged to study the relative functional groups of Chitin and chitoson in the peels of waste sources such as egg shells (country chicken and white leghorn), peels of Alium sepa (onion), Alium sativum (garlic), Zingiber officinale (Ginger) and Solanum tuberosum (Potato) to investigate the scope of usage as biomaterial. The percentage of extracted chitin was found to be the highest in the shells of country eggs (1.48g / 2g, 74%) followed by the peels of ginger (1.32g / 2g, 66%), onion (1.28g / 2g, 64%), white leghorn (1.16g / 2g, 58%), Potato (1.14g / 2g, 57%) and garlic (1.10g / 2g, 55%). Similarly, the percentage of deacetylated chitin, chitoson was found to be highest in ginger (0.97g/1g, 97%), shells of country eggs (0.85g / 1g, 85%), onion (0.83g/1g, 83%), shells of white leghorn (0.65g / 1g, 65%), Potato (0.63g / 1g, 63%) and garlic (0.58g / 1g, 58%) respectively. The functional properties of chitin and chitoson were studied by Fourier transform infra red spectroscopy (FTIR). The differences in spectra were observed in form of peak formation due to the shifts in bands. FTIR spectra for the deacetylated chitin showed reduced peaks attributed to loss of acetyl groups. The most pronounced peak reduction was observed in the deacetylated chitin from the peels of ginger and shells of country chicken eggs.
