The packaged beef samples were stored at 4 °C for 14 days. Analysis for
2-thiobarbituric acid reactive substances (TBARS test) was carried out
after 3, 6, 9 and 14 days of storage.
In a second assay, EVA films spiked with 6% and 9% of the functionalized
nanoclays (EVA NANO1.2% and EVA NANO1.8%, respectively)
were tested against the control film (EVA NANOC). Beef samples were
removed after 3, 6, 9 and 13 days for TBARS determinatio
