“…Several commercial scavengers have been developed based on ethylene chemisorption by KMnO 4 granules over clays or activated carbon [ 77 ]. Jiang et al (2013) [ 78 ] suggested an ethylene-removal method by oxidation at low temperatures over a platinum catalyst on mesoporous silica. The catalyst was able to remove 50 ppm ethylene even at 0 °C.…”

“…Upon binding to ethylene, a resistance change occurred ( Figure 6 A); however, the sensor generated a significant signal of tested solvents such as acetonitrile and tetrahydrofuran, but the low concentrations of these compounds had little effect. Weber et al (2009) [ 78 ] developed a biosensor for the detection of ethylene and acetaldehyde produced by plants. In their system, ethylene was oxidized to acetaldehyde on PdCl 2 with Cu (I) based on the Wacker process, and the generated acetaldehyde was detected by a CHO-K1-derived sensor cell line AIR CHO-SEAP ( Figure 6 B).…”

The growing interest in food quality and safety requires the development of sensitive and reliable methods of analysis as well as technology for freshness preservation and food quality. This review describes the status of chemical and biological sensors for food monitoring and smart packaging. Sensing designs and their analytical features for measuring freshness markers, allergens, pathogens, adulterants and toxicants are discussed with example of applications. Their potential implementation in smart packaging could facilitate food-status monitoring, reduce food waste, extend shelf-life, and improve overall food quality. However, most sensors are still in the development stage and need significant work before implementation in real-world applications. Issues like sensitivity, selectivity, robustness, and safety of the sensing materials due to potential contact or migration in food need to be established. The current development status of these technologies, along with a discussion of the challenges and opportunities for future research, are discussed.

“…The quantity of ethylene and acetaldehyde is related to the metabolic state and to the quality of fruit (Chen, Zhang, Hao, Chen, & Cheng, 2015;Maffei, 2010). Weber et al (2009) developed and implemented a hybrid dual-channel catalyticbiological sensor system, able to quantify the two volatile substances in situ (Weber, Luzi, Karlsson, & Fussenegger, 2009). This biosensor is based on a mammalian cell line engineered for constitutive expression of an Aspergillus nidulans, which triggers quantitative reporter gene expression in the presence of acetaldehyde.…”

Development and use of reliable and precise detecting systems in the food supply chain must be taken into account to ensure the maximum level of food safety and quality for consumers. Spoilage is a challenging concern in food safety considerations as it is a threat to public health and is seriously considered in food hygiene issues accordingly. Although some procedures and detection methods are already available for the determination of spoilage in food products, these traditional methods have some limitations and drawbacks as they are time-consuming, labour intensive and relatively expensive. Therefore, there is an urgent need for the development of rapid, reliable, precise and non-expensive systems to be used in the food supply and production chain as monitoring devices to detect metabolic alterations in foodstuff. Attention to instrumental detection systems such as electronic noses, electronic tongues and biosensors coupled with chemometric approaches has greatly increased because they have been demonstrated as a promising alternative for the purpose of detecting and monitoring food spoilage. This paper mainly focuses on the recent developments and the application of such multisensor systems in the food industry. Furthermore, the most traditionally methods for food spoilage detection are introduced in this context as well. The challenges and future trends of the potential use of the systems are also discussed. Based on the published literature, encouraging reports demonstrate that such systems are indeed the most promising candidates for the detection and monitoring of spoilage microorganisms in different foodstuff.

Apart from benefiting the pharmaceutical industry, synthetic biology can be also useful in the agronomical sector where plant based genetic elements can be engineered to enhance the rate of carbon fixation, assess fruit quality and generate synthetic organelles (Bar-Even et al 2010;Bonacci et al 2011Bonacci et al , 2012Weber et al 2009;Fig. 16.1).…”

Synthetic biology, an amalgamation of different fields including biology, computer science, physics and chemistry is estimated to grow to a value of $ 4.5 billion in 2015. It finds application in diverse areas such as healthcare, energy, agriculture, food additives and industrial chemicals. The role of synthetic biology for production of biodrugs as well as designer crops has been explored in the present study along with regulation of synthetic biology in the stated domains. The initial sections cover the recent developments in the synthetic biology derived biodrugs and designer crops. Emerging socio-economic issues such as biosafety, biosecurity, intellectual property rights form the later part of the study. Authors have also discussed about evolving a consolidated governance system with the aim to stimulate the growth and to minimise the risks involved in the biodrugs as well as designer crops based on synthetic biology.
