Decontamination of Bacillus subtilis Spores in a Sealed Package Using a Non-thermal Plasma System

Disinfection of chicken fillets in packages with atmospheric cold plasma: effects of treatment voltage and time

“…The ozone concentration in packages was calculated based on the instruction provide by the manufacture and published literature (Keener et al . ; Kronn et al . ).…”

“…Ozone formation in packages was measured with a Dr€ ager short term detector tube (Dr€ ager Safety AG and Co., Lubeck, Germany) immediately after an ACP treatment. This method was selected for ease of use and upon the recommendation by the researchers who used a similar device for fresh food products (Keener et al 2012). To insure that ozone content taken from the packages fell in the measurement range of Dr€ ager tubes, smaller volumes of gas samples (less than 5 ml) were collected with a 5-ml syringe from a treated package.…”

“…The headspace gas in the syringe were expelled into the tube and then quickly disconnected, allowing a total flow volume of 100 ml to pass through (volume required based on manufacturer's instructions). The ozone concentration in packages was calculated based on the instruction provide by the manufacture and published literature (Keener et al 2012;Kronn et al 2015).…”

In-Package Air Cold Plasma Treatment of Chicken Breast Meat: Treatment Time Effect

“…Trays were treated for 0, 60, 180, or 300 sec. Temperature and humidity of the laboratory were recorded during every replicate of the experiment [23,24].…”

“…e syringe volume was expelled into the detector tube and then removed, allowing a total flow volume of 100 mL to occur (volume required based on the manufacturer's instructions). e observed gas concentration was then multiplied by the ratio of the detection tube volume over the syringe volume [24]. It is important to note the ozone gas measured by the Drager Ozone Method relies on oxidation of indigo to form isatin [27].…”
