The trans-disciplinary aspects of the embryonic field of electrostatic spraying have provided a major motivation to researchers for the development of novel techniques for spraying of protective coatings to perishable food commodities for enhanced shelf-life, protective agents for health and hygiene in addition to other applications of sprays to manufacturing, transportation, agriculture, environment, medical facilities and devices. It has become the motives behind the renewed curiosity in the usage of the electrostatics in liquid based sprays. This provides an efficient and uniform transportation of liquid based agents which avoids the wastage of natural resource with enhanced performance. Edible coatings and incorporation of nutrition and active ingredients may improve fruit quality providing foodstuffs supplemented with extra flavour and a delicious, tantalizing and mouth-watering appearance. Electrostatic spray technology for coating of antioxidants and edible films for food products and fruits preservation is a sustainable development strategy in this revolutionary technology era that has gained a lot of attention owing to its importance in enhancing the shelf life of foods keeping its nutritional and sensory properties. Electrostatic disinfection and sanitization has gained a lot of attention and people became more alert about health and hygiene during the COVID-19 pandemic. Although few research initiatives have been taken over the past years, the work largely remains in the nascent stage as far as field-scale technology development and commercialization is concerned. These technological and life sustaining technologies will overall lead to improvement in the quality of life. A significant value of the charge-to-mass ratio (Q/M) of 4.83 mC/kg was achieved at applied air pressure of 4 bar and liquid flow rate of 130 ml/min at a target distance of 10 cm from the nozzle tip.

SummaryA critical assessment was carried out to investigate the impact of electrostatic spray coatings as compared to dip coatings on tomatoes which were conducted at 30 ± 2°C and 60% RH for a period of 30 days. In this paper, the impact of developed polysaccharide‐based coatings (alginate and cellulose coatings with clove oil) and commercially available wax‐based coatings (VMW50+) was compared to that of uncoated tomatoes. The application of alginate and cellulose‐based electrostatically charged sprays were found to significantly (p < 0.05) reduce the weight loss, firmness, colour and bioactive compound degradation and overall flavour loss as compared to uncoated and dip‐based coating during the storage period of 30 days. Moreover, alginate and cellulose based electrostatically charged spray coating was more efficient in delaying the spoilage of tomatoes by 20 days as compared to uncoated one. A significant level of charge‐to‐mass ratio has been achieved which confirmed the chargeability of coating materials. These findings confirmed the capability of electrostatically charged sprays to extend the shelf life and preserve the overall quality of tomatoes during storage.
