Abstract

The aim o this study was to investigate chemical, microbiological and sensory quality of sous-vide cooked Luciobarbus esocinus (Heckel, 1843) during chilled storage. Moisture, ash, fat, protein, salt, pH, total volatile basic nitrogen (TVB-N), thiobarbituric acid reactive substances (TBARs), counts of aerobic mesophile bacteria, aerobic psychrophilic bacteria and yeast-mold were determined in raw material. The sensorial, chemical and microbiological changes of products obtained under the cold storage were analysed in 3 days interval with 3 replicates.


The data obtained from chemical analysises was evaluated statistically; the differences amongst different cooking temperature applied groups interm of moisture, protein, fat and ash were found unsignificant (p>0.05). But pH, TVB-N values in groups during storage period was found significant (p<0.05).


The total earob psychrophile bacteria, total areobic mesophile bacteria and yeast-mold counts at groups treated different cooking temperature were found unsignificant (p>0.05).


It was observed that products prepared according to the sous-vide method are liked considerably.


In conclusion; it was determined that application of sous-vide technology had a positive affect upon shelf life of fish products.
