Effect of frozen storage on quality characteristics in carp (Cyprinus carpio L. 1758) fed with diets comprising different ratios of sunflower seed meal (original) (raw)

2012

Abstract

In this study, carp were fed for 12 weeks with experimental diets incorporated with different ratios of sunflower seed meal and the alterations in biochemical parameters of carp fillets during 6 months of frozen storage at -18 °C were determined. In this context, 4 diets were prepared comprising incremental levels of sunflower seed meal (0%-K, 15%-AT15, 30%-AT30, 45%-AT45). Furthermore, the mineral composition (P, Ca, K, Na, Mg, Zn) of experimental diets and fish flesh was assessed and it was concluded that the difference observed in diets regarding with mineral content did not affect the flesh. Through 6 months of storage, TBA, TVB-N and FFA values were determined monthly and TBA, TVB-N and FFA values were increased in all groups corresponding to storage (P<0.05).
