This study was conducted to investigate the resistance of Escherichia coli O157:H7 to 222-nm krypton-chlorine(KrCl) excilamp and 254-nm low-pressure Hg lamp (LP lamp) treatment according to growth temperature. As growth temperature decreased, lag time of E. coli O157:H7 significantly increased while the growth rate significantly decreased. Regardless of growth temperature, the KrCl excilamp showed higher disinfection capacity compared to the LP lamp at stationary growth phase. KrCl excilamp trea...

This study was conducted to investigate the effect of salt content during radio-frequency (RF) heating on rate of temperature increase, dielectric properties (DPs), and reduction of pathogens in pistachios. Also, the effect of RF heating on pistachio quality of varying salt content was determined. Pistachios of different salt content (0, 100, and 330 mg sodium/serving) were inoculated with Salmonella enterica and treated in a 27.12-MHz RF heater. The RF heating rate increased when salt content w...

Abstract We examined the control effect of a 222-nm KrCl excilamp on foodborne pathogens on alfalfa seeds and compared it with a conventional 254-nm low-pressure (LP) Hg lamp. When the 222-nm KrCl excilamp treated seeds at 87, 174 and 261 mJ/cm 2 , the log reductions of Escherichia coli O157:H7 ( E. coli O157:H7) were 0.85, 1.77, and 2.77, respectively, and Salmonella Typhimurium ( S . Typhimurium) experienced log reductions of 1.22, 2.27, and 3.04, respectively. When the 254-nm LP Hg lamp was a...

Abstract Salsa is a liquid-solid food containing jalapeno and serrano peppers, which result in multistate outbreak in 2008. Storage temperature and sodium chloride (NaCl) concentration of salsa vary depending on the climate, season, and type of product. In this regard, effect of growth conditions, namely, low temperature (15 °C) or NaCl concentration (4.5%) on the resistance of Escherichia coli O157:H7 ATCC 35150 to ohmic heating was identified in this study. Cells of E. coli O157:H7 ATCC 35150 ...

Abstract The purpose of this study was to evaluate the effectiveness of the combination treatment of lactic acid immersion and saturated or superheated steam (SHS) on inactivation of foodborne pathogens on cantaloupes. Saturated steam (SS) treatments were performed at 100 °C, while SHS treatments were delivered at either 150 or 200 °C. Escherichia coli O157:H7, Salmonella Typhimurium and Listeria monocytogenes -inoculated cantaloupes were exposed to 2% lactic acid or sterile distilled water for ...

Abstract Hurdle technology, in which preservation techniques are combined, has been of interest to scientists aiming to ensure microbiological food safety. We investigated the synergistic effect of UV-C irradiation and ohmic heating on the inactivation of foodborne pathogens. UV-C irradiation and ohmic heating were applied to buffered peptone water and tomato juice inoculated with pathogens simultaneously or sequentially. A synergistic bactericidal effect of the simultaneous treatment was observ...

Computer vision has achieved impressive progress in recent years. Meanwhile, mobile phones have become the primary computing platforms for millions of people. In addition to mobile phones, many autonomous systems rely on visual data for making decisions, and some of these systems have limited energy (such as unmanned aerial vehicles also called drones and mobile robots). These systems rely on batteries, and energy efficiency is critical. This paper serves the following two main purposes. First, ...

In this study, we developed a washing system capable of decontaminating fresh produce by combining the Spindle, which detaches microorganisms on sample surfaces, and a 222-nm krypton-chlorine (KrCl) excilamp (Sp-Ex), and investigated their decontamination effect against Escherichia coli O157:H7, Salmonella Typhimurium, and Listeria monocytogenes on apple ( Malus domestica Borkh.) and bell pepper ( Capsicum annuum L.) surfaces. Initial levels of the three pathogens were approximately 10 8 CFU/sam...
