摘要：
Desalted cod products are already marketed, although still presenting some problems. Fresh raw materials and good manufacturing practices during salting, drying and desalting are essential to improve their quality and shelf life. The production of off-odor, hydrogen sulfide, trimethylamine, ornithine, putrescine, cadaverine, histamine, indole, hydrolyzed gelatin and ammonia was investigated in 127 bacterial strains isolated from dried/wet salted cod, later desalted either at 4 or 24°C. Desalting could either introduce or recover off-odor, sulfide hydrogen and/or ornithine producing strains. Cod desalting at 4°C is of great importance in order to improve the shelf life and safety of cod desalted products. © 2002 by The Haworth Press, Inc. All rights reserved.
