*Values are mean of 3 determinations of mean ± SD (n = 3)

**Values are mean of 15 determinations of mean ± SD (n = 15)

^a–hValues within same row with different superscript differ significantly (p ≤ 0.05)

^xValues are significantly different from their corresponding PP (polypropylene) packed samples (p ≤ 0.05)
