All fungi isolated from climacteric fruits had reduced mycelial growth when held in 0.1 and 1 µL L-1 ethylene but those from non-climacteric fruits showed no effect of ethylene. The finding was unexpected and suggests that fungi that colonise climacteric fruits are advantaged by delaying growth when fruits start to ripen. Since non-climacteric fruits do not exhibit any marked increase in ethylene, colonising pathogens would not need such an adaptive response.]]> Tue 03 Sep 2019 18:08:23 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:34804 -1 of ethylene at either 5, 10 or 20 °C, whilst in a parallel experiment, Navel oranges were exposed to ≤0.001, 0.1 and 1 µL L^-1 ethylene at either 1 or 10 °C. Changes in external and internal postharvest quality parameters were assessed for up to 8 weeks for 'Afourer' mandarins and 10 weeks for Navel oranges. At all storage temperatures, high levels of ethylene were found to increase the level of calyx senescence, weight loss, loss of fruit firmness and respiration rates. Also, there were significant effects of ethylene and storage temperatures on total soluble solids (TSS) content, titratable acidity (TA), and ethanol accumulation in both citrus species. Continuous exposure to high ethylene also significantly reduced vitamin C and ferric reducing antioxidant power (FRAP) in 'Afourer' mandarins after 8 weeks of storage. Overall, ethylene treatments had a significant effect on both the external and internal qualities of the fruit during storage. The relationship between ethylene concentrations and storage temperatures demonstrate that lowering atmospheric ethylene levels at reduced storage temperatures maintain fruit quality during long term storage.]]> Tue 03 Sep 2019 17:58:57 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:41193 Thu 28 Jul 2022 11:12:21 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:1901 Sat 24 Mar 2018 08:33:07 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:25705 sulfate > nitrate with no difference between sodium, potassium and calcium ions. The effectiveness of sodium halides on browning was fluoride > chloride = bromide > iodide = control. Polyphenol oxidase (PPO) activity of tissue extracted from chloride- and fluoride-treated slices was not different to control but when added into the assay solution, NaF > NaCl both showed lower PPO activity at pH 3-5 compared to control buffer. The level of polyphenols in treated slices was NaF > NaCl > control. Addition of chlorogenic acid to slices enhanced browning but NaCl and NaF counteracted this effect. There was no effect of either halide salt on respiration, ethylene production, ion leakage, and antioxidant activity. Conclusion: Dipping apple slices in NaCl is a low cost treatment with few impediments to commercial use and could be a replacement for other anti-browning additives.]]> Sat 24 Mar 2018 07:28:22 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:28202 Sat 24 Mar 2018 07:23:53 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:23324 Sat 24 Mar 2018 07:13:31 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:23322 Sat 24 Mar 2018 07:13:31 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:55060 Mon 08 Apr 2024 12:31:58 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:41730 Fri 12 Aug 2022 10:39:26 AEST ]]>
