Carotenoides totais em resíduos do camarão Litopenaeus vannamei

Abstract

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.

Total carotenoids and antioxidant activity of fillets and shells (in natura or cooked) of “Vila Franca” shrimp (Litopenaeus Schmitti) in different intervals of storage under freezing

“…Sowmya et al (2014) also reported that shrimp waste is the major source of carotenoid astaxanthin. Seabra et al (2014) found 42.74 µg/g of total carotenoids in fresh waste of Pacific white shrimp (Litopenaeus vannamei), which is a concentration higher than in the present study.…”

Pink and white shrimps from the Brazilian coast: pigment identification, antioxidant activity and microbial quality under different freezing-times

“…Carotenoids are mainly supplied to shrimps by algae ingestion, being essential for communication and reproduction, since shrimps accumulated them in their carapace for attraction, warning, and camouflage (Mezzomo & Ferreira, 2016). Although this, their contents detected in the crushed shells of the three species studied were lower than those detected by Sowmya & Sachindra (2012), in acetone-extracts of Penaeus indicus shells (47.86 μg g -1 ), or by Seabra et al (2014), in hexane: isopropanol extracts of the L. vannamei shells (42.74 ± 1.75 μg g -1 ).…”

“…Also, studies of Seabra et al (2014) on the TC of shells of L. vannamei stored for 0-180 days under freezing (in polyethylene packages, at -28.3 °C ± 3.8), and then, homogenized with hexane: isopropanol (60:40 v/v), showed a significant reduction (ρ < 0.05) in such contents along the time.…”

Carciniculture solid waste increases the morphophysiological characteristics of tomato seedlings

“…The transformation of these residues into co-products with added value is vital to minimizing problems in production and achieving greater efficiency in processing (Beerli et al, 2004). Shrimp processing residues have been used for animal feed production, chitin extraction, carotenoid pigments, remediation of contaminated water, plant disease control, water stress and environmental impacts (Vieira et al, 2011;De Souza et al, 2015;Seabra et al, 2014;Núñez-Gómez et al, 2016;Ghini et al, 2006;Bezerra et al, 2017;Decker et al, 2016;Sumardiono and Siqhny, 2019).…”
