The rising environmental problem of plastic packaging waste has led to the development of sustainable alternatives, particularly for food packaging. Polyhydroxyalkanoates (PHAs) are biodegradable, thermoplastic polyesters. They are employed in the production of various products, including packaging films. The bio-based nature and appropriate features of PHAs, similar to conventional synthetic plastics, have garnered significant attention from researchers and industries. The current study aimed to produce biodegradable food packaging using mango peel (a major agricultural waste) with enzymatic hydrolysis and PHAs synthesis. Mango peel is the hub for macro-and micronutrients, including phytochemicals. The process includes an enzymatic hydrolysis step that converts complex carbohydrates into simple sugars using mango peel as a substrate. The produced sugars are used as raw materials for bacteria to synthesize PHAs, which are a class of biodegradable polymers produced by these microorganisms that can serve as packaging materials in the food industry. To solve environmental problems and increase the utilization of agricultural by-products, this review presents a practical method for producing food packaging that is environmentally friendly.
塑料包装废弃物日益严重的环境问题促使了可持续替代品的发展，尤其是用于食品包装的替代品。聚羟基脂肪酸酯（PHA）是可生物降解的热塑性聚酯。它们被用于生产各种产品，包括包装薄膜。PHA的生物基性质和与传统合成塑料相似的适当特性，已引起研究人员和行业的极大关注。当前的研究旨在通过酶解和PHA合成，利用芒果皮（一种主要的农业废弃物）生产可生物降解的食品包装。芒果皮富含大量宏量营养素和微量营养素，包括植物化学物质。该过程包括一个酶解步骤，以芒果皮为底物将复杂碳水化合物转化为单糖。产生的糖用作细菌合成PHA的原料，PHA是这类微生物产生的一类可生物降解聚合物，可用作食品工业中的包装材料。为了解决环境问题并提高农业副产品的利用率，本综述提出了一种生产环保型食品包装的实用方法。
