Abstract

The incorporation of plant extract into biopolymers is an environment-friendly method of fabricating bioactive films (BFs) with multifunctional properties for food packaging. The current work explores the development of carboxymethyl cellulose (CMC)-based BFs by combining Ficus religiosa (Peepal) extract (PLE) and Psidium guajava (Guava) extract (GLE) in varying ratios. The impact of extract concentration on the films' physiochemical and functional properties was examined. The structural analysis of the films showed good compatibility between the polymer and extracts. The findings indicate that BFs with PLE and GLE in a 50:50 ratio exhibited better mechanical properties than other films. All the BFs enhanced oxidative stability and UV-blocking properties. Among all combinations, the CMC/GLE¹⁰⁰ film (having only GLE and CMC) exhibited the highest antioxidant and UV-blocking properties although transparency is slightly reduced. On employing the CMC/GLE¹⁰⁰ film as UV protective packaging, it was able to preserve the color and shape of grapes even after 48 h of direct UV exposure. CMC/GLE¹⁰⁰ film, when applied to pack fried items, exhibited enhanced oxidative stability. Overall, CMC/GLE¹⁰⁰ film can find potential applications for packaging fruits and fried items.

Highlights

CMC/GLE¹⁰⁰ film exhibited enhanced oxidative stability for packing fried items.
CMC/GLE¹⁰⁰ film showed potential as UV-blocking film for fruits' packing.
CMC/GLE¹⁰⁰ film exhibited very good antioxidant potential.
CMC/GLE¹⁰⁰ film has very good UV-blocking properties but decreased transparency.
BFs with PLE/GLE in a 50:50 ratio exhibits very good mechanical properties.

添加榕/瓜爪哇番石榴提取物的羧甲基纤维素基生物活性食品包装膜：添加剂比例变化的影响

将植物提取物掺入生物聚合物中是一种制备多功能食品包装生物活性膜的环保方法。本研究以不同比例的无花果（Peepal）提取物（PLE）和番石榴（guajava）提取物（GLE）为原料，研究了羧甲基纤维素（CMC）基生物燃料的开发。考察了提取液浓度对膜的理化性能和功能性能的影响。膜的结构分析表明，聚合物与萃取物具有良好的相容性。结果表明，以50:50的比例添加PLE和GLE的BFs具有较好的力学性能。所有BFs都增强了氧化稳定性和抗紫外线性能。在所有组合中，CMC/GLE100膜（仅含有GLE和CMC）表现出最高的抗氧化和紫外线阻隔性能，但透明度略有降低。采用CMC/GLE100薄膜作为防紫外线包装，即使在直接紫外线照射48小时后，也能保持葡萄的颜色和形状。CMC/GLE100薄膜用于包装油炸食品时，表现出增强的氧化稳定性。总的来说，CMC/GLE100薄膜可以在包装水果和油炸食品方面找到潜在的应用。强调CMC/GLE100薄膜在包装油炸食品时表现出增强的氧化稳定性。CMC/GLE100薄膜具有作为水果包装防紫外线膜的潜力。CMC/GLE100薄膜表现出良好的抗氧化能力。CMC/GLE100薄膜具有很好的防紫外线性能，但透明度降低。PLE/GLE比例为50:50的bf具有良好的力学性能。
