Abstract

The world needs sophisticated packaging that can detect product deterioration to decrease waste and maintain safety. Ethanol and methanol are undetectable fumes that show signal deterioration in packed salads and juices. This is the first investigation to connect a possible solution is polysaccharide packaging with nanoparticles that act as alcohol detectors. Most people discuss materials, nanoparticles and sensors separately, but we integrate them. We studied over 4 years of studies to show how nanoparticles and natural material structure create a sensor. Chemistry, nanoparticle manufacturing, dispersion within the material and how alcohol causes a color change, luminescence or electrical variation, is the emphasis. We created a guide that matches metallic particles, nanoclays and other natural nanofillers with the best sensing technologies. Researchers made these smart packaging films by using methods like precision casting, extrusion or by making nanoparticles right within the material. To test how well they worked, they would put them in ethanol or methanol vapors, which are similar to the gasses that come from rotting food. They employed a wide range of methods to study and explain how the film was put up, how nanoparticles were spread out and most importantly, how well it worked to find alcohol signals and keep food fresh for longer. Optimizing nanoparticle-natural material bonding is a true transformational factor that is the key to establish a reliable and food-safe sensor. Safety rules, toxicity evaluations and measures to prevent dangerous compounds from entering food were all gathered for this. This approach makes biodegradable packaging possible, helping the environment. Future intelligence includes packaging that monitors many spoilage indications, sensors that connect to your phone and scalable, ecologically friendly manufacturing techniques. This review guides food packaging development and maintaining food freshness and quality supervision. © 2025 Elsevier Ltd
