Effect of Lactobacillus Acidophilus 1 m metabolites on microbial and biochemical quality criteria of frozen Basa Fish (Pangasius Bocourti) fillets [electronic resource].

Includes reference.

The present work was planned to investigate the effect of different Lactobacillus acidophilus filtrate levels on microbial and biochemical quality criteria of imported basa fish (Pangasius bocourti) fillets and heavy metals concentrations i.e. lead (Pb), cadmium (Cd}, copper (Cu), zinc (Zn) and iron (Fe). Fish fillets were immersed in cold distilled water containing (v\v) 1%, 1.5% and 2% metabolites for 2 min. Each treatment was packed in polyethylene bags, put in foam dishes and all treatments were stored at -18•c for 30 days. Results showed that frozen contained low residue levels of cadmium (Cd 0.06), copper (Cu 0.42), zinc (Zn 3.0) and iron (Fe 4.98) but lead not detected. Also, basa fillets contained (on wet weight basis) high moisture (81.76 %) and low protein (11.24%), high lipid (4.99%) and ash (1.88%) contents. During frozen storage, Lb. acidophilus filtrate levels decreased total plate count (TPC), psychrophilic, proteolytic and lipolytic bacteria in all treatments compared to control samples.
