Abstract:
Tilapia is an excellent source of macro and micronutrients. It has a very short shelf life (12
to 24 hours) at normal temperature. Preservation method is very important to extend its
shelf life. Combining salting and drying is one of important preservation methods of
Tilapia. This study was focus on effect of brining time on the quality of wet salted drled
Tilapia fish. The research evaluated the effect of different brining times on the
physicochemical properties, sensory characteristics and ensure microbial qualities of wet
salted dried Tilapia fish. Five diffrent time period were used to wet salting the Tilapia fish
(Tr:i minute ,Tz:30 minutes, T::1 hour, T+:1 hour 30 minutes, Ts:2 hours). Physicochemical
analysis revealed that increasing the salting time ash and protein content increased but
moisture, fat content and pH decreased. Color L* value (Lightness) was increased but a*
value (Green to red) and b* value (Blue to yellow) were decerased according to increasing
wet salting time, Sensory evaluation was conducted by 30 semi trained panalist, using
seven point hedonic scale to assess texfure, flavor, taste, color and overall acceptabilify.
The results showed that 2 hours wet salting Tilapia fish (T:) received the highest preference
scores among tested duration. Microbial analysis after 48 hours of incubation the fungi and
bacterial colonies of microbes were reduced according to increasing salting time of Tilapia.
Tiiapia fish at 2 hours of wet salting (Ts) had beiter results than the other treatments. The
study offers valuable insides into the wet salted preservation of Tilapia, demonstrating that
optimal brining time significantly enhances the effectiveness of the preservation process.
