- In vitro bioaccessibility of macro and trace elements in biofortified and conventional farmed gilthead seabream (Sparus aurata) and common carp (Cyprinus carpio)Publication . Barbosa, Vera; Anacleto, Patrícia; Maulvault, Ana Luísa; Oliveira, Helena; Marmelo, Isa; Ferraris, Francesca; Raggi, Andrea; Ventura, Marta; Sobczak, Małgorzata; Eljasik, Piotr; Panicz, Remigiusz; Tsampa, Kalliopi; Karydas, Andreas G.; Carvalho, Maria Luisa; Martins, Marta; Cubadda, Francesco; Marques, AntónioBiofortification is a promising strategy to improve the nutrient profile of farmed fish but requires consideration of the nutrient bioaccessible fraction. In this study, the in vitro bioaccessibility of macro and trace elements was investigated in biofortified and conventional farmed gilthead seabream and common carp, also taking into account the effect of cooking (by steaming). Biofortification enhanced iodine and selenium levels in seabream and carp fillets. Steaming increased iodine and selenium contents in biofortified seabream, and increased selenium and decreased copper levels in biofortified carp. Higher iodine bioaccessibilty (> 80%) was observed in biofortified seabream compared to biofortified carp (45%). In both species, selenium, iron, and zinc bioaccessibility was ≥ 70%. Upon steaming iodine and iron bioaccessibility decreased in seabream, while selenium bioaccessibility decreased in carp. The consumption of steamed biofortified seabream and carp contributes to significantly higher daily intakes of iodine (up to 12% and 10%, respectively) and selenium (up to 54% and above 100%, respectively) compared to conventional counterparts. The present study demonstrates the potential of developing innovative biofortified farmed fish using natural sustainable feed ingredients to improve the intake of important nutrients for human health.
- Safety and efficacy of a feed additive consisting of endo‐1,4‐beta‐xylanase (produced by Aspergillus oryzae DSM 33700) (RONOZYME® WX (CT/L)) for all poultry species and all Suidae (DSM nutritional products ltd)Publication . EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP); Bampidis, Vasileios; Azimonti, Giovanna; Bastos, Maria de Lourdes; Christensen, Henrik; Durjava, Mojca; Dusemund, Birgit; Kouba, Maryline; López‐Alonso, Marta; López Puente, Secundino; Marcon, Francesca; Mayo, Baltasar; Pechová, Alena; Petkova, Mariana; Ramos, Fernando; Villa, Roberto Edoardo; Woutersen, Ruud; Brantom, Paul; Louro, Henriqueta; Svensson, Kettil; Novo, Natalia Alija; Brozzi, Rosella; Innocenti, Matteo Lorenzo; Casanova, Jordi Ortuño; Pizzo, Fabiola; Pettenati, ElisaThe additive RONOZYME® WX (CT/L) contains endo-1,4-beta-xylanase produced with a genetically modified strain of the filamentous fungus Aspergillus oryzae; the additive is currently authorised for poultry for fattening, weaned piglets, pigs for fattening, lactating sows and laying hens. The applicant has requested to change the production strain, substituting strain A. oryzae DSM 26372 with A. oryzae DSM 33700, and to extend the use of the additive to all poultry species and all Suidae. RONOZYME® WX (CT/L), manufactured with the production strain A. oryzae DSM 33700, did not give rise to safety concerns with regard to the genetic modification of the production strain. No viable cells of the production strain nor its DNA were detected in an intermediate product representative of both final formulations of the additive. RONOZYME® WX (CT/L) was considered safe for all poultry species and all Suidae at the recommended inclusion levels. The use of RONOZYME® WX CT and L manufactured with the production strain A. oryzae DSM 33700 raised no concerns for consumers. RONOZYME® WX L is not an eye irritant; however, no conclusions could be drawn on the potential of RONOZYME® WX CT to be an eye irritant. Both formulations are not irritant to the skin, but due to the lack of data, the FEEDAP Panel was not able to conclude on the potential of both formulations of the additive to be skin sensitisers. Due to the proteinaceous nature of the active substance, the additive is considered a respiratory sensitiser. The additive manufactured by A. oryzae DSM 33700 raises no safety concerns for the environment. The additive has the potential to be efficacious in all poultry species and all Suidae at 100 and 200 FXU/kg complete feed, respectively.
