Extraction of Melanin from Squid Ink and It's Activity as Food Bio Preservatives

Squid ink is known to contain melanin, a natural pigment with potential biopreservative properties. This study aimed to extract melanin from squid ink and evaluate its biopreservative activity. Squid ink was collected and processed to isolate melanin using a series of extraction techniques. The extracted melanin was then tested for its antimicrobial properties against common foodborne pathogens.The extracted melanin exhibited significant biopreservative activity, showing inhibitory effects against various bacteria and fungi. These findings suggest that squid ink melanin could be utilized as a natural preservative in food products. In conclusion, the extraction of melanin from squid ink proved successful, demonstrating promising biopreservative potential. Further research is warranted to explore its application in food preservation on an industrial scale.
