The results demonstrate that additions of lotus leaf powder (LP)
and barley leaf powder (BP) had positive effects on oxidative and
color stability in cooked ground pork during refrigerated storage for
10 days. The ground pork made with addition of LP and BP had lower
TBARS values, POVs and CD compared to control (−) during storage.
The LP ground pork had significantly higher a⁎ values and less lipid
oxidation, as measured by TBARS values, POVs and CD concentrations,
than the BP ground pork over the 10 day storage period. The addition
of BP had an inhibitory effect on lipid oxidation when compared to the
control (−) over the 10 day period. No significant differences in the
overall acceptability were seen on addition of LP and BP. The samples
with BP diminished warmed-over flavor during storage. Thus, lotus
and barley leaf extracts, widely used vegetables in most Asian
countries appear to be useful ingredients in ground pork, providing
a source of natural antioxidants that are safe and enhance the
oxidative stability of the processed meat.The results demonstrate that additions of lotus leaf powder (LP)
