Sažetak
Quality Index Method scheme was developed for raw bogue (Boops boops) and evaluated it in a shelf life study, using samples from wild fish aggregations at fish farms (BF) and from area not influenced by the fish farms (BW). Different environment influenced the shelf life of bogues ; thus the maximum ice storage, evaluated from cooked samples, was found to be 17 days for BF and 12 days for BW. The calculated Quality Indexes (QIs) evolved linearly with storage time on ice (QIBF = 0.968x + 0.583, R2=0.947, Std. Err. Est. = 1.41 ; QIBW = 1.212x + 0.474, R2= 0.972, Std. Err. Est. = 0.95). The multivariable analysis was used to identify the most effective variables during spoilage evolution. The sum of all demerit points showed higher correlation (R>0.99) then any single parameters itself, indicating that the individual parameters could not replace the usage of 20 demerit points QIM scoring scheme in sensory assessment. The impact of farming cages was observed in fat (BF >19% ; BW <2%) and water content (BF = 55% ; BW = 77%) of bogues, but also in pH, dielectric properties, thiobarbituric acid index and volatile amine changes. High correlations of these parameters with storage time and sensory assessment were observed.
