sectors, notably food production and packaging, by integrating nanoparticles (NPs) to improve taste, texture, and shelf life. Despite these benefits, their distinct physicochemical properties raise concerns about potential health risks differing from conventional materials. This paper critically reviews current research on nanoparticle toxicity in food, focusing on exposure routes, toxic mechanisms, and regulatory perspectives. Key gaps in understanding are identified, urging further research to fill knowledge voids and refine safety assessment methodologies. Understanding these aspects is crucial for establishing comprehensive regulatory frameworks that ensure the safe integration of nanotechnology in food products while addressing public health concerns effectively.
Nanotechnology plays a crucial role in enhancing food products through various applications such as food preservation, additives, packaging, and nanosensors for detecting food pathogens [9]. Nanoparticles like Cu/CuO, Ag, MgO, TiO2, ZnO, carbon dots, and graphene are extensively used in food packaging due to their antimicrobial properties and ability to improve mechanical barriers and heat resistance compared to traditional methods [10]. Active packaging utilizing antimicrobial nanoparticles helps extend shelf life by inhibiting microbial growth and maintaining food freshness [11, 12]. Nanosensors are employed throughout the food supply chain to detect contamination and monitor food quality during processing, packaging, storage, and transportation [13, 14].

1. INTRODUCTION Nanotechnology integrates various scientific disciplines to manipulate matter at the atomic and molecular levels, yielding materials with unique physicochemical properties distinct from bulk counterparts [1]. Nanoparticles, defined as particles with dimensions between 1-100 nm, exhibit enhanced reactivity, catalytic behavior, and biological activity due to their increased surface area and unique quantum effects [2]. These properties make them valuable across industries, including agriculture and food processing, where they improve food quality, stability, and nutrient bioavailability [3].
Despite these advancements, concerns arise regarding human exposure to nanoparticles through ingestion of nanoparticle-enhanced foods and migration from packaging materials. Studies indicate potential health risks including protein denaturation, oxidative stress, DNA damage, and gastrointestinal issues associated with oral exposure to nanoparticles [15]. This necessitates rigorous assessment of nanoparticle toxicity and safety in food applications to ensure consumer health and regulatory compliance [5]. While nanotechnology offers significant benefits in improving food quality and safety, careful consideration and comprehensive studies are essential to mitigate potential risks associated with the use of nanoparticles in food products. Regulatory frameworks and advanced techniques for toxicity assessment are crucial in ensuring the safe integration of nanotechnology into the food industry.
In the food sector, nanotechnology has revolutionized processing techniques, offering benefits such as improved sensory properties, enhanced nutrient delivery, and extended shelf life [4]. Nanomaterials play crucial roles in food safety, packaging development, and functional food production, with ongoing research exploring their potential to combat food-related diseases and design personalized nutrition regimens [5].
This study examines the current research on nanoparticles applied across various sectors of the food industry, investigates their potential toxicity, and assesses their safety implications in food applications.
The application of nanotechnology in food systems also focuses on sustainability through innovations like nanoencapsulation for controlled nutrient release and fortification [6]. Despite these advancements, concerns persist regarding the safety and regulatory aspects of
