RESUMO:

Astaxanthin is found naturally in shrimp residues and can be extracted in varying ways. The extraction with vegetable oil contributes to stability from this carotenoid, retarding its oxidation. The objective of this study was to evaluate the physical and physical-chemical characteristics and the antioxidant capacity of the pigmented oils obtained from the extraction of astaxanthin from the shrimp waste (litopenaeus vannamei). The obtained pigmented oils of the shrimp waste (OW) and of the shrimp waste flour (OF) were evaluated for astaxanthin content, physical and physico-chemical characteristics and antioxidant capacity. The samples of OW and OF showed an astaxanthin content of 70.9 and 264.7 μg / g, respectively, where the decrease in moisture was responsible for this increase of 3.7 times. Likewise, its antioxidant power is directly associated with the astaxanthin content, however, some physical and physico-chemical characteristics of OF presented changes. Therefore, the pigmented oils from shrimp waste present a significant potential for the use in food as a natural antioxidant due to its antioxidant power, as well as the low price to obtain it.
