Fumigation with limonene showed no antifungal activity. Citral did not show full inhibition of green mould decay in Navel oranges, however the treatment did not cause fruit’s rind injury. It would be worthy to conduct further research as fumigation with citral has potential to provide an alternative decay control or green mould in citrus fruit.]]> Wed 28 Sep 2022 09:33:57 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:28818 -1 in air at 20°C for 1 to 4 h or dipped in an aqueous solution of the NO-donor compound, 2,2’- (hydroxynitrosohydrazino)-bis-ethanamine (diethylene triamine-nitric oxide; DETANO) at concentrations between 10 and 1000 mg L^-1 for 15 s to 60 min, followed by storage at 0°C in air. The most effective treatments were fumigation with 500 µl L^-1 NO for 1 h, and dipping in 500 mg L^-1 DETANO for 5 min. The ability of NO to inhibit the development of browning of different types of lettuces was further investigated on the cut surfaces of four fresh-cut lettuce types (‘Green Oak’, ‘Green Coral’, ‘Baby Cos’, and ‘Butter’) during storage at 5°C. The NO was applied to lettuce strips (i) by fumigation with NO gas for 2 h, (ii) by dipping in DETANO solution dissolved in 0.01 M phosphate buffer pH 6.5, or (iii) by dipping in an aqueous solution of the NO-donor compound, sodium nitroprusside (SNP). Treatment with NO gas, DETANO, or SNP inhibited the development of browning and extended the postharvest life of all four lettuce types. The optimum treatments were dipping in 500 mg L^-1 DETANO or SNP, which resulted in an approximately 60% increase in postharvest life over untreated lettuce slices.]]> Wed 26 Jul 2017 14:41:59 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:43924 -1) against both A. alternata and A. citri. The results showed that lemon aqueous extracts suppressed the mycelial growth and spore germination of both species in a concentration-dependent manner. The mycelial growth inhibition (MGI) for A. alternata varied between 31 to 68%, while for the A. citri the MGI varied between 14 to 49%. Scanning electron microscopy showed that lemon waste extracts affected the morphology of both species.These results indicate that the aqueous extracts of lemon by-products contain bioactive compounds which could be potentially useful as an alternative to synthetic fungicides for controlling Alternaria.]]> Wed 05 Oct 2022 10:31:22 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:34291 Tue 26 Feb 2019 14:15:01 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:36239 Tue 17 Mar 2020 12:32:29 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:36817 Brassica rapa subsp. chinensis) that examined the effect of fumigation with hydrogen sulphide and nitric oxide and subsequent storage at 10°C in air with and without the addition of 0.1 µL L^-1 ethylene. The results showed that treatment with nitric oxide increased the shelf life and decreased respiration rates for the pak choy heads during the storage. However, fumigation with H₂S alone or in combination with NO resulted in greater inhibition of respiration rate and extension in market life, and this effect was more pronounced in the presence of 0.1 µL L^-1 ethylene.]]> Thu 10 Jun 2021 14:07:03 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:26084 Sat 24 Mar 2018 07:39:49 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:29446 2) pre- Treatment in combination with cold storage has been shown to be an effective disinfestation treatment to kill quarantine pests such as fruit flies in horticultural produce. However, the effects of high CO₂ and cold treatments on fruit quality, including the development of chilling injury and offflavours, needs to be thoroughly examined. In this study, Navel oranges were treated with either air or 95% CO₂ in air for 48 h at 2°C then stored in air for up to 18 days at 2°C. Following treatment and storage, there was no evidence of any chilling injury and no significant changes in fruit soluble solids content (SSC) or titratable acidity (TA). Another storage trial examined the time taken for Navel oranges to recover from the 95% CO₂ treatment. In this experiment, fruit were stored at 2°C and ventilated with either air or 95% CO₂ in air for 70 h. After treatment, the fruit were stored in air and sampled after 1, 2, 3, 4, 5, 8, 9 and 10 days. The results showed that after the high CO₂ treatment, the levels of acetaldehyde significantly increased in CO₂- Treated fruit and ethanol whereas levels of ethanol decreased. However, within three days storage in air, levels of acetaldehyde returned to pre- Treatment concentrations. These results show the potential of using high CO₂ combination treatments as postharvest disinfestation treatments, which do not adversely affect fruit quality after treatment and storage. However more research is recommended to fully understand these fruit responses and their role in overall fruit quality.]]> Sat 24 Mar 2018 07:39:21 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:29692 Sat 24 Mar 2018 07:38:48 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:29135 Sat 24 Mar 2018 07:32:35 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:48464 Fri 17 Mar 2023 12:14:34 AEDT ]]>
