“…Nevertheless, studies have shown the detrimental effect of gaseous plasma species (excluding the etching effect) on insect mortality. Paul & Mahendran (2020) used indirect (200 V) plasma treatment (gaseous species) for T. castaneum disinfestation and found 100% mortality in adult insects after prolonged exposure of 24 h. Hence, it is possible to achieve mortality in internal feeder pupae but with the increased exposure time as there is no direct etching effect on insects.…”

Soybeans play a vital role in the world economy as an essential food commodity by fulfilling human dietary needs. Hence, the seeds are commonly transported and stored in bulk quantities in various parts of the world which ultimately results in infestation issues. Callosobruchus maculatus is one of the major storage pests that infest the soybean seeds and cause losses in both the quantity and quality of the seeds. Cold plasma (CP) is an emerging non-thermal disinfestation technique that can disinfest food grain. Hence, we have used low pressure (<2 mbar) CP at different voltages (1.0-2.0 kV) and exposure times (2-24 min) to disinfest the C. maculatus from soybeans. The maximum mortality of 100.00 ± 0.00%, 98.89 ± 1.92%, and 37.33 ± 8.08% was achieved in adult, pupae, and egg stage insects, respectively, after 24 min of prolonged CP exposure at 2.0 kV voltage. However, CP treatment (1.5 kV-18 min) induced only 11.11 ± 3.85% mortality in larval stage insects as they were well protected under soybean seed coat. During the experiment, we also identified the impact of insect sex and egg age on the CP treatment effectiveness. Further, we have also analyzed the egg-producing capacity of CP-treated adult insects before their death.Apart from disinfestation, the CP treatment also assisted the soymilk extraction and increased the extraction yield from 92.44 ± 1.02% (control) to 97.22 ± 0.19% after CP treatment (2.0 kV-12 min). Nevertheless, the FTIR and SDS PAGE results had not shown any changes in the quality of soymilk extracted after CP treatment. Practical applicationsSince the lab scale study was found to be effective against most of the C. maculatus life stages, it is possible to adapt the CP for large-scale disinfestation applications with essential modifications (i.e., pressure, conveyors) in the system's designs. Apart from that, CP also modifies the surface nature of the grains, hence the treatment also assists in increasing the extraction yield (milk, oil, and protein) and germination percentage of food grains.

Nowadays, demand for minimally processed food has increased globally very rapidly. However, the food preservation and the period of storage is a key challenge in front of the food processing industry.So to overcome this problem,recently widely used cold plasma technology which is an alternative method for heat treatment. It is a novel, non-heat transferable, nature-friendly, and money-saving technology which does not change the organoleptic characteristics of food and enhances the microbiological quality of food.It helps to preserve the natural aroma and flavour. Cold plasma technology is agrowingtechnique and it has significant potential to decrease the undesirable effects on nutritional as well as quality characteristics of food. The review evaluates the recent status of this technique in the food processing sector. As this is a grow ingmethod which is utilized in several food processing sectors they are listed below. Cold plasma technology shows promising results primarily in shelf life extension as well as in microbial inactivation.

“…Novel nonthermal approaches like ozonation [9], gamma irradiation [10] and cold plasma are emerging disinfestation techniques. Among which cold plasma is a potential disinfestation method against a wider range of insect species like Myzus persicae [11], Frankliniella occidentalis (Pergande), Frankliniella fusca (Hinds), Aedes albopictus (Skuse), Tetranychus urticae, Blattella germanica (L.) [12], Plodia interpunctella [13] and Tribolium castaneum [14,15]. Plasma composed of free radicals, reactive oxygen and nitrogen species, UV radiation, atoms in their ground, and excited states engenders destructive effects to the insects, thereby resulting in effective insect control.…”

Cold plasma is recognized and explored for a plethora of applications in the food and agricultural industry. This study investigated the influence of a continuous atmospheric pressure non-thermal jet plasma system on the mortality of Rhyzopertha dominica adults in whole wheat kernels and the changes in the milling and physicochemical attributes of the treated whole wheat. Air-filled packets of whole wheat kernels were artificially infested with R. dominica adults. The packages were carried by a continuous conveyor belt and treated with plasma at voltages ranging from 44-47 kV for 4-7 min. The mortality was determined after 24 h and milling yield, particle size, proximate composition, and color of plasma-treated and untreated wheat grains were also evaluated. The maximum mortality was 88.33% at 47 kV for 7 min. The milling yield, protein, and fiber content of wheat were enhanced with plasma treatment significantly. Thus the continuous atmospheric pressure jet plasma used in this study could be one of the practically implementable emerging techniques for the commercial disinfestation of packaged food products.
