Abstract
Degradation of food during transportation or storage poses a significant threat to its shelf life. Developing functional materials using sustainable components can serve as an environmentally friendly alternative to traditional food packaging, which contributes negatively to climate change. In this endeavor, carboxymethyl cassava starch-based films with various compositions of basil extract, available in aqueous (B) or freeze-dried (BS) forms, were obtained by extrusion. The inclusion of these extracts provided the starch film's antioxidant potential and contributed to increased tensile toughness. The highest concentration of BS yielded materials with outstanding UV protection capabilities and water resistance, showcasing remarkable improvements in hydrophobicity. The polyphenol release kinetic curves of the films with B at 15 % w/w and with BS, evaluated by the Weibull model, showed a Fick diffusion mechanism, underscoring the potential utility of these films as biodegradable and edible active packaging for lipophilic and acidic foods.
期刊介绍:
Food packaging is crucial for preserving food integrity throughout the distribution chain. It safeguards against contamination by physical, chemical, and biological agents, ensuring the safety and quality of processed foods. The evolution of novel food packaging, including modified atmosphere and active packaging, has extended shelf life, enhancing convenience for consumers. Shelf life, the duration a perishable item remains suitable for sale, use, or consumption, is intricately linked with food packaging, emphasizing its role in maintaining product quality and safety.
