Effect of Alpinia zerumbet essential oil on the shelf life of tambaqui fillets during short-term refrigerator storage

Abstract

We investigated the effect of Alpinia zerumbet essential oil on the quality and shelf life of tambaqui (Colossoma macropomum) fillets stored under refrigeration (10.0 ± 0.5 °C) for 14 days. The treatments were A. zerumbet essential oil at 0.75% v v-1 (AEO 0.75%), A. zerumbet essential oil at 1.5% v v-1 (AEO 1.5%) and a control (no essential oil). The sample quality and shelf life were determined by the total psychrotrophic count (TPC) and chemical parameters (pH, total volatile basic nitrogen, centesimal composition and thiobarbituric acid reactive substances - TBARS) at zero, seven and 14 days of storage time. The TPC decreased significantly (p < 0.05) with an A. zerumbetessential oil level of 1.5% until seven days of storage. The concentration of A. zerumbet essential oil at 0.75% resulted in lower pH, TBARS, and TVBN values in comparison with the other treatment and the control. Thus, A. zerumbet essential oil was efficient in extending the shelf life of refrigerated tambaqui fillets up to approximately seven days.

Proximate composition, fatty acids and nutritional indices of promising freshwater fish species from Serrasalmidae family

“…The lack of information related to the nutritional composition of Brazilian freshwater fish species from Serrasalmidae family associated with the fact that tambacu is a hybrid makes difficult the comparison of our results with those in the literature. Considering fish farmed in Brazil, similar values of lipids were reported for Colossoma macropomum and Piaractus mesopotamicus X Colossoma macropomum (Castro et al, 2007;Silva et al, 2018;Sousa et al, 2019), while Piaractus mesopotamicus has been usually reported with higher lipid content than C. macropomum and P. mesopotamicus X C. macropomum (Andrade et al, 1995;Nitz et al, 2019). Moreover, some authors observed similar ash content between P. mesopotamicus and C. macropomum (Nitz et al, 2019;Sousa et al, 2019).…”

In the present study, although no difference (p > 0.05) was observed in ash content among PM, CM and PC, a similarity (p > 0.05) in moisture, lipid, and protein contents was only observed between PC and CM.…”

Influence of some natural preservatives in controlling the shelf -life of sea bass (Dicentrarchus labrax) during cooled storage

“…In plenty of condition, there is another necessity for increasing seafood quality through extracts from botanical resources which proved the best efficacious usages to increase food storage (Appendini and Hotchkiss, 2002, Hanusova et al, 2009, Erkan et al, 2011, Falguera et al, 2011and Sousa et al, 2019.
