 en Brine treatment, smoking and storage techniques: their effects on the microbial quality of smoked mackerel.
Eyabi Eyabi G. D, Hanson S. W. and Barlow P. J.


Sample of Atlantic Mackerel ( Scomber scombrus check for this species in other resources ) were treated with 8 brine for 2 hours with slight agitation while untreated fish served as control. Both treated and untreated fish were loaded in a Torry Afos Mini Kiln set at 50° C. The temperature was raised to 80° C after one hour and maintained at this temperature throughout the smoking process.

Samples of treated and untreated fish (U8 and B8) were removed after 8 hours of smoking and the last batch removed at the end of 16 hours smoking (U16 and B16). Analyses for growth, identification and coverage of fish surface with mould and for sensory attributes of discoloration, off odours, brittleness (texture) and personal preference were carried out for freshly smoked and stored samples. Samples for storage were packaged in clear polythene and stored in an environmental cabinet.

Bringing and smoking time retarded mould growth, controlled discoloration, off odour development, softening of the fish and positively affected personal preference.

Penicillium check for this species in other resources sp was identified as the incriminated species.
