There is a great potential to use seafood by-products to create new beneficial products for customers. In a continued exploration of new chemical compounds from seafood by-products, jumbo squid (Dosidicus gigas) skin pigmented methanolic extracts (JSSE) were evaluated for their antimicrobial and antimutagenic activities. Pigments of JSSE were extracted with a yield of 635 mg/g and oxygen radical absorbance capacity-fluorescein (ORAC) with 178 mol TE/g JSSE using optimal conditions: 25 °C and 5 min of sonication, established by factorial analysis. The antimicrobial activity of JSSE was evaluated using the agar diffusion method. The JSSE showed more than 50% inhibition against Haemophilys influenza, Listeria monocytogenes, Staphylococcus aureus, and Candida albicans. The high antimicrobial activity of JSSE (50%), but not in the TA100 strain (
