Abstract

Trachurus trachurus (locally called kote in Western Nigeria) is a table fish. During processing like poaching and smoking, fish come in contact with water, smoke and high temperatures, which may interfere with the nutrient contents and are potential sources of reactive di-carbonyl compounds (RDCs) and polyaromatic hydrocarbons (PAHs). This study was therefore conducted to determine the level of RDCs and PAHs in raw and processed Trachurus trachurus fillet; skin, head and bones (SHB). Fish samples were prepared by poaching and smoking (charcoal and wood). RDCs and levels of 5 individual PAHs including fluorene, phenanthrene, anthracene, benz(a)anthracene and naphthalene were determined in raw, poached and smoked (charcoal and wood) Trachurus trachurus using standard methods. Results indicated that all processing methods significantly increased (p
