However, maintaining the quality and nutritional value of these products during storage is being difficult in comparison to whole fruits and vegetables. In actual, the procedures used in the fresh-cut industry may intensify the deterioration caused by physical damage by minimal processing. Commonly, the quality degradation, discolouration, loss of moisture, loss of firmness, microbial load increase, and loss of nutrients and flavor occur in the fresh-cut product after minimal processing. To maintain the quality and increase the shelf-life of the fresh-cut product, it is necessary to use various techniques, including physical, chemical, and nondestructive processes. 1. Due to alteration in lifestyles, the consumption of the fresh-cut product (FCP) has been increased in the last decade [1, 2]. 2. UNIVERSITY OF MICHIGAN 08/04/19 Cold plasma can kill 99.9% of airborne viruses, U-M study shows.

ANN ARBOR—Dangerous airborne viruses are rendered harmless on-the-fly when exposed to energetic, charged fragments of air molecules, University of Michigan researchers have shown.

They hope to one day harness this capability to replace a century-old device: the surgical mask. The U-M engineers have measured the virus-killing speed and effectiveness of nonthermal plasmas—the ionized, or charged, particles that form around electrical discharges such as sparks. A nonthermal plasma reactor was able to inactivate or remove from the airstream 99.9% of a test virus, with the vast majority due to inactivation. Achieving these results in a fraction of a second within a stream of air holds promise for many applications where sterile air supplies are needed. “The most difficult disease transmission route to guard against is airborne because we have relatively little to protect us when we breathe,” said Herek Clack, U-M research associate professor of civil and environmental engineering.

TRENDS IN BIOTECHNOLOGY - JUNE 2018 - The Potential of Cold Plasma for Safe and Sustainable Food Production

Chemical residues of agricultural pesticides of varying structure can be degraded to safe or less-toxic structures using cold plasma. Cold-plasma-mediated control of contaminants, along with the promotion of seed germination and plant growth, offers alternatives to current pesticides and fertilizers for agriculture. Controlling plasma reactive species formulations in dry and liquid delivery formats advances the potential for understanding and successful translation to multiple points along the agriculture and food sectors. Employing predictive microbiology, process optimization tools and a systems approach with controlled reactive species formulations may achieve risk- or problem-tailored solutions for whole food systems.

The regulation applicable in Poland defines the maximum number of aerobic mesophilic microorganisms at the level of 103–104 CFU/ml only in pasteurized fruit and vegetable juices38. The regulation of the European Commission (EC) specifies only the limit of bacteria from the group of E. coli in un-pasteurized fruit and vegetable juices39. There is limited information regarding the permissible number of total aerobic microflora in freshly squeezed, un-pasteurized tomato juice. The data available in the literature on the total number of microorganisms in fresh fruit and vegetable juices differ greatly (from 2 to 7 log10 CFU/ml) depending on the method of juice production, the type of fruit and vegetable cultivation, variety, and storage conditions40,41,42,43.

Italy is the second leading hazelnut producer after Turkey, covering 13% of the global production. Hazelnuts (Corylus avellana L.) - Tonda Gentile Trilobata cultivar - are widely cultivated in Piedmont, where they adapt well to the continental climate and reach excellent quality. The confectionery industry processes 90% of the domestic production, while the remaining 10% is consumed fresh, both in-shell and shelled.

The former are generally used for fresh consumption, while the latter are used as a raw material by the food and cosmetic industries. Hazelnuts can be contaminated by fungal species, part of the Aspergillus genus, that can produce aflatoxins. In particular, A. parasiticus can produce four aflatoxins (B1, B2, G1, G2), while A. flavus can only produce B1 and B2.

ICEF11 - Emerging technologies for targeted food processing. NATO Advanced Research Workshop - MARS 2011 - Plasma for bio-decontamination, medicine and food security. FOOD PRODUCTION 03/01/12 Cold plasma shows potential for Listeria reduction in packaged RTE foods – research. Scientists from Denmark said that Listeria contamination was on the increase in many European countries – particularly in meat and seafood products. They noted that surface contamination of RTE meats may occur during processing as Listeria “can persist in the processing environment and be transferred to products from equipment such as slicers”.​

The Listeria contamination of RTE meats from a Maple Leaf plant in Canada in 2008 which killed 23 people is the most high-profile example of this in recent years. In their study, Susanne Knochel et al examined the ability of CAPP to combat this through surface decontamination of the product. The research, published in the journal Food Microbiology last month, defined plasma as “an ionised quasi-neutral gas that can be generated by applying an electric field to an initially electrically neural gas”.​ Toxins 2017, 9(5), 151; Mycotoxin Decontamination of Food: Cold Atmospheric Pressure Plasma versus “Classic” Decontamination.

Niemira, Ph.D. When developing and maintaining an effective sanitation program for a food handling environment, you face a lot of challenges. These include the design of processing equipment for proper access to all surfaces for cleaning, selection of sanitizers and cleaning tools matched to the needs of each processing line, training for shift workers and cleaning crews, and the monitoring and verification of sanitation efficacy. For the food industry, however, almost nothing presents as many problems for antimicrobial sanitation as the difficulties presented by biofilms. How Are Biofilms Organized? Biofilms are tightly grouped masses of microorganisms, clustered together in complex communities with concomitant extracellular polymeric substances excreted by the bacterial communities to provide water-impermeable cellular protection.

Cold plasma rapid decontamination of food contact surfaces contaminated with Salmonella biofilms. Cross-contamination of foods from persistent pathogen reservoirs is a known risk factor in processing environments. Industry requires a rapid, waterless, zero-contact, chemical-free method for removing pathogens from food contact surfaces.

Cold plasma was tested for its ability to inactivate Salmonella biofilms. A 3-strain Salmonella culture was grown to form adherent biofilms for 24, 48, or 72 h on a test surface (glass slides). These were placed on a conveyor belt and passed at various line speeds to provide exposure times of 5, 10, or 15 s. The test plate was either 5 or 7.5 cm under a plasma jet emitter operating at 1 atm using filtered air as the feed gas. Practical Application Pathogens such as Salmonella can form chemical-resistant biofilms, making them difficult to remove from food contact surfaces.

As consumers demand higher-quality, more-nutritious foods, they also look for less processing combined with a longer shelf life. The food-processing industry has made great strides toward this and has also put in place numerous intervention technologies designed to ensure a more-sanitary manufacturing environment.

The industry currently uses some novel processing methods for the decontamination of food and food contact surfaces.

Researchers at the Institute of Food Research have tested a new technique to ensure fresh produce is free of bacterial contamination.

Plasmas are a mix of highly energetic particles created when gases are excited by an energy source. They can be used to destroy bacteria but as new research shows, some can hide from its effects in the microscopic surface structures of different foods. Eating fresh fruit and vegetables is promoted as part of a healthy lifestyle, and consumers are responding to this by eating more and in a greater variety. Ensuring fruit and vegetables are free from contamination by food poisoning bacteria is crucial, as they are often eaten raw, without cooking or processing that kills off bacteria. A move away from current chlorine-based decontamination is driving the search for new, safe ways of ensuring fresh fruit and vegetables are free from bacterial contamination without reducing quality or flavour.
