Table 1

Total phenol content (TPC) and total flavonoid content of (TFC) of PPEs and chitosan-PPE films.

Sample	TPC	TFC
PME	7.98 ± 0.55^c	2.37 ± 0.13^ab
PEE	11.1 ± 0.82^d	3.86 ± 0.4^c
CH-PME	4.30 ± 0.2^b	1.90 ± 0.02^a
CH-PEE	5.14 ± 0.08^b	2.59 ± 0.24^b
CH	2.51 ± 0.25^a	0.09 ± 0.002^a

All values are expressed as mg/g means ± standard deviation (n = 3). Alphabetic letters indicate the significant difference within a column using a one-way analysis of variance (ANOVA).
