Astaxanthin is found naturally in shrimp waste and can be extracted in several ways. The extraction with vegetable oil, contributes to its stability by slowing down oxidation. The objective of this study was to characterize physical and physicochemically and evaluate the antioxidant capacity of pigmented oils obtained from extraction of astaxanthin from shrimp waste (Litopenaeus vannamei) with vegetable oil. Oil pigmented from shrimp waste (OW) and oil pigmented from flour shrimp waste (OF) obtained were assessed for astaxanthin content, physical and physicochemical and antioxidant capacity. Oil pigmented from flour shrimp waste (OF) have a high astaxanthin content, as well as antioxidant activity, however, presented changes physical and physicalchemical characteristics. Therefore, pigmented oils has significant potential in food preparations as a natural antioxidant.
