A B S T R A C TStrawberries are highly sensitive to deterioration by microbial decay after harvest and Botrytis cinerea is one of the most common diseases that infect them. Previous work has reported successful extension of strawberry shelf life through the use of chlorine dioxide (ClO 2 ) gas treatments. In this study, California strawberries purchased at retail stores were treated with continuously generated ClO 2 gas over concentrations ranging from 0.01 to 5.0 mg/L for durations ranging from 7 to 1000 min to determine how ClO 2 gas impacts fungal mortality and fruit quality as a function of treatment concentration, treatment duration, and ClO 2 absorption by the fruit. Repeated measures and Gompertz models were used to infer on the efficacy of the ClO 2 gas, and a novel method was used to quantify the ClO 2 absorption by fresh produce. It was found that ClO 2 gas treatments have minimal effect at delaying the onset or growth rate of Botrytis cinerea for treatments followed by incubation at 4 or 22 C even when corrected for natural variability of Botrytis cinerea presence among batches of strawberries, indicating that treatments are not sufficient for shelf-life extension.

“…Furthermore, Arango et al . () studied the ClO 2 gas consumption of strawberries and found that minimal contact time to ClO 2 gas was required for the maximum consumption to be achieved. Therefore, the longer exposure time could result in the more effective ClO 2 utilisations, especially at low treatment temperatures.…”

“…The study by Lee et al (2015) on the effects of temperature on diffusion coefficient (D) of gaseous ClO 2 showed that the gas diffused through air at a significantly lower rate as the temperature of the environment decreased, that is the D values of ClO 2 gas through air at 23 and 5°C are 0.145 and 0.129 cm 2 s À1 , respectively. Furthermore, Arango et al (2014) studied the ClO 2 gas consumption of strawberries and found that minimal contact time to ClO 2 gas was required for the maximum consumption to be achieved. Therefore, the longer exposure time could result in the more effective ClO 2 utilisations, especially at low treatment temperatures.…”

Summary The aim of this study was to investigate the effects of gas level and treatment condition on antimicrobial efficacy of ClO2 gas against Salmonella enterica Typhimurium on grape tomato (Lycopersicon esculentum). Grape tomatoes were dip‐inoculated with inoculum of S. enterica Typhimurium TISTR 292 (ATCC 13311) (9.79 ± 0.39 log CFU mL−1) and allowed to dry before treatments. The pre‐inoculated samples were exposed to 0.15–0.85 mg of ClO2 gas, for up to 58 min. The treatments at 4 and 25 °C resulted in population reductions of S. enterica Typhimurium of up to 3.95 ± 0.22 and 7.37 ± 0.39 log CFU per fruit, respectively. The population reduction results were used to construct statistical models to predict efficacy of ClO2 gas. The second‐order equations for treatments at 4 and 25 °C had R2 of 0.87 and 0.95, respectively, and indicated that efficacy of ClO2 gas was significantly influenced by ClO2 gas level, exposure time and treatment temperature.
