#### 3.1.2 Applications in Different Food Sectors
These electronic olfactory systems adeptly capture volatile compounds arising during the decomposition process, thereby facilitating nuanced assessments of spoilage [102; 103; 104]. By discerning the distinctive odors emanating from different meat types as they undergo degradation, electronic noses serve as invaluable resources in identifying early signs of spoilage, preempting potential health hazards, and advancing the overarching goal of minimizing food waste. The integration of electronic noses for freshness monitoring transcends the purview of individual food items, projecting their potential impact in revolutionizing food storage practices and distribution networks. As these devices continue to evolve, incorporating advanced sensing technologies and pattern recognition algorithms, their efficacy in detecting and deciphering the intricate spectrum of volatile compounds associated with food deterioration is poised to intensify. Ultimately, the adoption of electronic noses as stalwart guardians of freshness bolsters the commitment towards sustainability, food security, and the assurance of untainted and safe consumption experiences. The convergence of e-nose technology with intelligent packaging systems embodies a nascent frontier teeming with transformative potential in curbing food wastage. In this burgeoning arena, the amalgamation of compact e-nose devices, exemplified by products like the FOODsniffer, has already made inroads into the consumer market, empowering individuals to independently assess the freshness status of their food items [Retrieved from www.myfoodsniffer.com, accessed on 12 August 2023 at 09:30]. Yet the true metamorphic potential crystallizes in the ongoing research endeavors aimed at seamlessly integrating e-nose sensors directly into the fabric of food packaging materials. [PERSON] et al. successfully inkjet printed SnO2 sensors onto polyimide foil [105]. The trajectory of embedding e-nose sensors within packaging materials heralds an unprecedented paradigm shift in minimizing food wastage. By enabling continuous monitoring of packaged food conditions, this approach addresses a fundamental challenge: the uncertainty surrounding item integrity and freshness, even prior to reaching the consumer. Through this integration, food producers, distributors, and consumers stand to glean a comprehensive understanding of the product's status across its lifecycle, empowering timely interventions and informed decision-making. This transformative potential is rooted in the bedrock of sensor technology advancements and innovative integration methodologies currently under exploration. As electronic noses evolve to discern an expanding spectrum of volatile compounds associated with freshness, their efficacy in safeguarding food quality is poised for a meteoric rise. This advancement seamlessly aligns with the overarching objective of reducing food waste, as the monitoring-centric approach guarantees consumption at the optimal point of freshness. In the symphony of technological innovation and sustainability aspirations, electronic noses are poised to orchestrate a harmonious evolution in the food industry--a revolution characterized by quality, efficiency, and reduced waste.
