“…However, these sensors have some demerits such as expensive, very complex, and low portability due to difficulty of miniaturization. 94,98,115 Several successful attempts regarding the application of e-nose for monitoring the spoilage of meat and meat products prove the efficacy of this analytical method. Incorporation of various sensing elements to sensor arrays will enable e-noses to offer novel prospects for detecting specific markers.…”

The food packaging sector has experienced much development since its inception. In the past few decades, innovations in packaging sector have led to the development of smart packaging (SP) systems that carve a niche in a highly competitive food industry. SP systems have great potential for improving the shelf‐life, and safety of food products apart from their basic roles of protecting the products against unwanted biological, chemical, and physical damage and keeping them clean. Indicators and sensors, SP components, are used for real‐time monitoring of meat quality and subsequently inform the retailers and consumers about the freshness, microbiological, temperature, and shelf life status of the products. Barcodes and radio‐frequency identification tags are employed in meat packaging for real‐time information about the authenticity, and traceability of the products in the supply chain. Recently, innovations in SP technologies resulted in fast, sensitive, and effective detection, sensing, and record keeping of freshness, microbiological, and shelf life status of meat and meat products. The SP system shows promise for extensive utilization in the meat industry in response to the consumer appreciation for safe, and quality meat products, as well as their waste reduction notions. This paper gives an updated overview of ongoing scientific research, and recent technological advances that offer the perspectives of developing smart meat packaging systems that are capable of monitoring the physical, microbial, and chemical changes of the package contents from producer to the point of sale and even beyond, and remediating potential adverse reactions.

“…Other studies in different institutions have done some projects that apply temperature modulation through metal-oxide sensors [5][6][7][8][9]. On the other hand, some works have been focused on researching frequency spectrum analysis in order to improve the gas sensor performance, discriminating odors of similar response under noisy conditions, and modulation techniques using processing methods such as: cluster analysis, principal components, and neural networks, where a signal from a device for data acquisition was acquired and afterwards the gas sensor response was analyzed [10,11]. The work done by Anindita and Kanak about "A Temperature Modulation Circuit for Metal Oxide Semiconductor Gas Sensor" was taken as reference in this research in order to try to apply equivalent procedures, but obtaining different results [12].…”

This paper consists of the design and implementation of a simple conditioning circuit to optimize the electronic nose performance, where a temperature modulation method was applied to the heating resistor to study the sensor’s response and confirm whether they are able to make the discrimination when exposed to different volatile organic compounds (VOC’s). This study was based on determining the efficiency of the gas sensors with the aim to perform an electronic nose, improving the sensitivity, selectivity and repeatability of the measuring system, selecting the type of modulation (e.g., pulse width modulation) for the analytes detection (i.e., Moscatel wine samples (2% of alcohol) and ethyl alcohol (70%)). The results demonstrated that by using temperature modulation technique to the heating resistors, it is possible to realize the discrimination of VOC’s in fast and easy way through a chemical sensors array. Therefore, a discrimination model based on principal component analysis (PCA) was implemented to each sensor, with data responses obtaining a variance of 94.5% and accuracy of 100%.
