Abstract

ABSTRACT A large part of the Northeast Atlantic cod caught with trawls is landed frozen, processed, and sold thawed. Many trawlers have adapted a fishing practice termed ‘buffer towing’, causing probability for poor exsanguination and fillet redness. Here, the effect of buffer towing upon color and hemoglobin concentration in cod loin section is studied, and the development of TVB-N during chilled storage of thawed cod. No significant differences were proven for redness or hemoglobin concentration in loin from cod exposed to regular haul-back or buffer towing. Neither were significant differences found in TVB-N levels during chilled storage at 0 and 4°C.

缓冲拖曳对冻融大西洋鳕鱼品质的影响

东北大西洋用拖网捕捞的鳕鱼大部分是冷冻、加工、解冻后出售的。许多拖网渔船采用了一种称为“缓冲拖曳”的捕鱼方法，这可能会导致放血不良和鱼片发红。本文研究了缓冲拖曳对鳕鱼腰切片颜色和血红蛋白浓度的影响，以及解冻鳕鱼冷藏过程中TVB-N的发展。在常规拖曳或缓冲拖曳中，鳕鱼腰的红度或血红蛋白浓度没有显著差异。在0°C和4°C冷藏期间，TVB-N水平均无显著差异。

期刊介绍： The Journal of Aquatic Food Product Technology publishes research papers, short communications, and review articles concerning the application of science and technology and biotechnology to all aspects of research, innovation, production, and distribution of food products originating from the marine and freshwater bodies of the world. The journal features articles on various aspects of basic and applied science in topics related to: -harvesting and handling practices- processing with traditional and new technologies- refrigeration and freezing- packaging and storage- safety and traceability- byproduct utilization- consumer attitudes toward aquatic food. The Journal also covers basic studies of aquatic products as related to food chemistry, microbiology, and engineering, such as all flora and fauna from aquatic environs, including seaweeds and underutilized species used directly for human consumption or alternative uses. Special features in the journal include guest editorials by specialists in their fields and book reviews covering a wide range of topics.
