Freshness changes and shelf life prediction of cultured Tilapia (Oreochromis niloticus) during chilled storage
In this study, freshness changes and shelf life prediction of cultured tilapia (Oreochromis niloticus) stored at 0, 5 and lOoC were investigated. Total viable counts (TVC), the count of Pseudomonas spp. and total volatile basic nitrogen(TVB-N) in newly-caught tilapia were determined as 4.79±0.60 log cfii/g , 4.00±0.75 log cfu/g and 8.08±0.46 mg/100 g, respectively. At the end of shelf life, TVC, the counts of Pseudomonas spp. and TVB-N increased to 8.08±0.26 log cfij/g, 7.66±0.10 log cfu/g, and 20.1±1.66 mg/lOOg, respectively, which were utilized to develop exponential spoilage shelf life model. RRS model of shelf life was developed by the shelf life at 0, 5 and 10°C, its accuracy factor and bias factor were from 1.06 and 1.01, indicating the model was useful to effectively predict the shelf life of chilled Tilapia at the range of 0 and 10°C.
