Total carotenoids in white shrimp (Litopenaeus vannamei) wasteAiming at the utilization of shrimp processing wastes, this study carried out an analysis of total carotenoids in white shrimp (Litopenaeus vannamei) waste and in the dried shrimp waste meal. The analysis of total carotenoids was carried out in fresh wastes and processed flour (day 0) and after 60, 120 and 180 days of frozen storage. The fresh shrimp waste had 42.74µg/g of total carotenoids and the dried meal 98.51µg/g. After 180 days of frozen storage, total carotenoids were significantly lower than day 0 (p < 0,05). Considerando-se o possível aproveitamento dos resíduos, provenientes do beneficiamento do camarão, realizouse, neste trabalho, a determinação da concentração de carotenoides totais dos resíduos do camarão Litopenaeus vannamei e da farinha obtida após secagem. As análises foram realizadas nos resíduos in natura e na farinha recém-processada (dia 0) e aos 60, 120 e 180 dias de armazenamento sob congelamento. Os resíduos frescos apresentaram, no dia 0, teores de 42,74 µg/g de carotenoides totais e, a farinha recém-processada, de 98,51 µg/g. Após 180 dias de armazenamento, sob congelamento, os teores de carotenoides totais diminuíram significativamente, quando comparados com os do dia 0 (p < 0,05).Palavras-chave: carotenoides, astaxantina, camarão, farinha.
