Abstract

ABSTRACT In Brazil, tilapia represented 57% of the total fish production. This study aimed assess the influence of different pre-slaughter methods (live chilling in ice/water (LC); anesthesia with the essential oils Ocimum americanum (OA) or Lippia alba (LA) and mechanical spiking (SP), on the meat quality parameters of Nile tilapia. The rigor mortis index showed faster onset in the LC group compared to the OA and LA groups after 3 hours. The pH value, TVB-N, and K-value remained unchanged, indicating no detrimental effects on meat quality. Mechanical spiking and essential oil anesthesia had comparable effects to live chilling.

不同屠宰方法对尼罗罗非鱼（Oreochromis niloticus）综合品质的影响

摘要在巴西，罗非鱼占鱼类总产量的57%。本研究旨在评估不同屠宰前方法（冰/水中活冷藏（LC）；用香茅（OA）或白皮（LA）精油麻醉和机械加标（SP）对尼罗罗非鱼肉质参数的影响。与OA和LA组相比，LC组在3小时后出现尸僵指数更快。pH值、TVB-N和K值保持不变，表明对肉质没有不利影响。机械加标和精油麻醉的效果与活体冷冻相当。

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.
