UV barrier properties and the oxygen permeability (OP) of alginate based films loaded from 0 to 30% CNCs (w/w polymer, dry basis) were evaluated at 0, 50, and 70% RH. The best performing film was used to coat chicken breasts and lipid oxidation was assessed during storage through lipid peroxide value (PV), thiobarbituric acid reagent substances (TBARS) quantification and color variability measurements. Results showed promising UV barrier effects and 25% decrease of OP at 70% RH when 30% CNCs were loaded in alginate films. Edible coating on chicken breasts also demonstrated a decrease of PV and TBARS at day 1 and 3 when 30% CNCs were used and no oxidative changes were indicated by chicken color.
研究了从 0 到 30%（按干重计）浓度的纳米纤维素（CNC）负载的海藻酸钠基薄膜在 0、50 和 70%相对湿度（RH）下的紫外线阻隔性能和氧气透过率（OP）。在海藻酸钠薄膜中负载 30%的 CNC 时，性能最佳的薄膜被用于涂覆鸡胸肉，并通过脂质过氧化物值（PV）、硫代巴比妥酸反应物（TBARS）定量和颜色可变性测量来评估贮藏期间的脂质氧化情况。结果表明，当 30%的 CNC 负载在海藻酸钠薄膜中时，薄膜具有良好的紫外线阻隔效果，在 70%RH 下 OP 降低了 25%。在鸡胸肉上使用 30%的 CNC 作为可食用涂层，在第 1 天和第 3 天可以降低 PV 和 TBARS，并且鸡肉颜色没有显示出氧化变化。
