Researchers developed edible food packaging films from pearl millet starch nanoparticles produced by acid hydrolysis, finding that increasing nanoparticle concentration improved mechanical strength, reduced water vapor transmission, and enhanced biodegradability up to 92.89%, offering a sustainable plastic-free alternative for food packaging.

Abstract Pearl millet, known for its adaptability to challenging agro‐climatic conditions, emerges as a valuable candidate for biopolymer‐based packaging. The AHB 1200 cultivar, distinguished by its high starch content, provides a reliable source for biopolymer extraction. The conversion of pearl millet starch into nanoparticles by acid hydrolysis represents a cutting‐edge method to enhance biopolymeric materials. The inclusion of these nanoparticle concentrations (0.5%, 1%, 5%, and 10%) into the film results in improved mechanical characteristics, reduced water permeability, and increased biodegradability. Furthermore, the lowered water solubility and reduced water vapor transmission rate (WVTR) further underscore their positive contributions. This study comprehensively examines various film properties, encompassing WVTR from 7.23 ± 0.06 to 4.57 ± 0.08 g/m 2 /s, moisture content, solubility from 35.29 ± 0.51% to 30.09 ± 0.15%, burst strength from 1102.11 ± 0.99 g to 1535.71 ± 0.63 g, thermal stability, and biodegradability from 65.16% to 92.89%. The findings highlight the notable advancements achieved through the integration of starch nanoparticles. Practical applications Pearl millet (AHB 1200) starch nanoparticle‐based edible films offer a versatile solution for specialized food packaging needs because of their compatibility with various food types, dairy products, fresh produce, and so on. These films act as a protective barrier and maintain product freshness during storage and transit. It also has enhanced mechanical strength and tear resistance and provides vacuum‐sealed packaging, ensuring an extended shelf life. Beyond their functional benefits, these edible films present an opportunity for branding and marketing differentiation. The films made with pearl millet have an earthy, natural appearance that fits with today's customer inclination for sustainable and environmentally friendly goods. This allows manufacturers to leverage the films as a means of conveying their commitment to environmentally friendly practices, enhancing their brand image and consumer loyalty. Furthermore, the biodegradability of these films is preferred over plastic waste. They offer a viable alternative to traditional plastic packaging, aligning with global initiatives to reduce the environmental impact of packaging materials.
