The chemopreventive role of fruits is associated with their phytonutrient contents bearing antioxidative
properties. Therefore, pomegranate peel powder was incorporated by 1, 2 and 5% of the high fat pastry and
compared their efficiency in stability of some fat constants in relative to the control pastry sample (pomegranate
peel powder free) within the storage period at incubator temperature (50°±1°C) as an accelerator condition for
deterioration. Total phenolics content, antioxidation activity, expressed by DPPH radical scavenging activity,
were highly detected in the pomegranate peel powder. It was also found that as the pomegranate peel powder
amount increased in the tested fatty pastry, the total phenols (as GAE mg/100gm) and consequently radical
Scavenging Activity (RSA %) was increased. The free fatty acids (FFA% as oleic Acid) were lowered as a
result of increasing the pomegranate peel powder amount in the tested fatty pastry. It was also lower at the end
of the storage period as a result of increasing the pomegranate peel powder amount in the tested fatty pastry.
The same pattern was also detected in case of peroxide value (POV as meq/Kg) and acid value (AV as mg/g) of
fatty pastry during the storage period. In general, it could be concluded that the pomegranate peel powder could
be considered a good tool in antioxidizing and delay the peroxidation process of the fatty products.
Cosequently, it could be used in therapeutic applications either in the good or worst conditions |
