Important changes have taken place
recently in consumer’s preferences towards improving their health by ingesting functional food products enriched with bioactive compounds.
The aim of this study was to investigate the functionalizing effects induced by the addition of
pistachio nuts (Pistacia vera (PV)) into simit
kebab, a meat-based product.
Physicochemical properties (ph, day matter, fat content and color values) and
fatty acid composition analyses
were carried out on raw simit kebab samples. Total phenolic content (TPC) and total antioxidant
capacities (AC) analyses were carried out on
both raw and cooked samples to determine the effects of cooking at 200ºC/20min.
Also, the storage influences
(at 4oC/3 days) on the simit, the kebab was examined too.
Significant differences in physicochemical properties were observed between the
control and treated samples depending on both PV concentration and storage time
(p<0.05). Color values of L* and a* in
treated samples (7.5 and 10%) were significantly declined (p<0.05) in the course of storage
when compared to the control samples. The TPC and AC in the treated samples showed a gradual and potential increase
as the PV concentration increased. The values of TPC and DPPH inhibition ratio
in 10% PV added samples were 33.60% and 53%
higher than that expressed in the control samples, respectively. However,
the storage period caused a reduction in both TPC and AC values of the raw samples.
PV addition to simit kebab potentially increased
the total polyunsaturated fatty acid (PUFA) concentration. Hence, data suggest that Pistacia vera is a good candidate for a
new approach to functionalize and
enhance the nutritional properties of meat-based products.
