TitleAproveitamento e valorização de algumas espécies de tubarão  ( Document )
Author(s) / Editor(s)Nunes, M.L.; Batista, I.; Mor�o de Campos, R.; Viegas, A.
DescriptionUpgrading of shark species in Portugal

A pesca do tubar�o (s. l.) em Portugal assumiu nos �ltimos anos alguma relev�ncia devido, principalmente, � boa cota��o, no mercado internacional, do �leo do f�gado destas esp�cies, em particular do barroso e da lixa, que s�o os mais ricos em esqualeno. Por outro lado, a carne destas esp�cies � muitas vezes subaproveitada devido �s suas caracter�sticas s�pidas e, tamb�m, ao facto do seu consumo n�o estar generalizado. Com vista ao aproveitamento e valoriza��o destas esp�cies realizaram-se ensaios de filetagem e apreciou-se o efeito de v�rios tipos de tratamento na remo��o de constituintes azotados, principais respons�veis pelo sabor caracter�stico e, por vezes, menos agrad�vel da carne de algumas esp�cies. Realizaram-se tamb�m estudos de conserva��o dos filetes em congelado e ensaiou-se a prepara��o de produtos salgados e secos. No que respeita ao �leo do f�gado, procedeu-se � sua caracteriza��o f�sico-qu�mica e estabeleceram-se correla��es altamente significativas entre alguns �ndices f�sicos e qu�micos.

The shark fishery in Portugal was very significant in the last years mainly due to the high price of shark liver oil in the international market. Nevertheless, the consumption of these species is not widespread on account of the characteristics of their meat and also due to some superstitions about sharks. In order to use and upgrade these species some filleting trials were done and the effect of different treatments on the elimination of nitrogenous compounds, some of them responsible for the characteristic flavour of shark meat, was studied. The prepared fillets were frozen and the evolution of their quality during storage was followed. The preparation of salted and dried products was also tried. Shark liver oils were characterised by physical and chemical methods and a few highly significant correlations were established between some chemical and physical indices.
