After treatments, then stored for 28 days in air at 20°C, 80% RH (control) and in air containing < 0.005 or 0.1 µL.L^-1 ethylene at 20°C and 100% RH. Weight loss, peel colour, calyx abscission, ethylene production, respiration rate, soluble solids content (SSC), titratable acidity (TA) and acceptability index were assessed. The results showed that pre-storage UV-C treatment, followed by different storage conditions significantly affected the quality of limes during storage. UV-C treatment significantly affected peel degreening at 20°C in all storage conditions, whereas treated limes showed significantly slower in peel degrening than the control. These effects reduced over the storage time, with the exception of fruits stored in < 0.005 µL.L^-1 ethylene which still produced a significantly higher in Hue value after 21 days storage relative to the control. UV-C treatment affected ethylene production during storage under all storage conditions. This effect also diminished with storage time. UV-C treatment did not affect the respiration rate, SSC or TA for all storage conditions. The UV-C treated limes had higher acceptability index than untreated limes up to 14 days storage at 20°C. Storage conditions significantly affected ethylene production, with limes that stored in air exhibiting higher ethylene production than fruits stored in the < 0.005 or 0.1 µL.L^-1 ethylene atmosphere. Storage conditions also significantly affected weight loss, with fruits stored in air showing greater weight loss compared to the other storage conditions. The results suggest that a pre-storage UV-C treatment, followed by storage in less than 0.1 µL.L^-1 ethylene atmosphere improves the quality of limes postharvest.]]> Wed 31 Oct 2018 15:20:11 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:33652 -1. Green peel color was visually assessed daily and a range of internal quality factors measured at the end of storage life (designated as green life). Results and discussion: Storage of limes at 30 °C resulted in a longer retention of green skin color than fruit held at the currently recommended temperature of 10 °C, whilst fruits stored at 20 °C had the shortest green life. Limes stored at all temperatures degreened more slowly as the ethylene level in the atmosphere was reduced. Internal quality, as measured by total soluble solids, titratable acidity and antioxidant activity, was not adversely affected by storage at the higher temperatures. Conclusion: Storage at a high ambient temperature and with exogenous ethylene at ‹0.1 μL L^-1 could have considerable economic benefits for limes grown in tropical climates in developing countries and possibly also in sub-tropical developed countries.]]> Thu 29 Nov 2018 13:20:29 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:33420 -2 UV-C and 0.5 µL L^-1 1-methylcyclopropene (1-MCP) treatments both separately and in combination. After treatment, fruit were stored in ethylene free (i.e. air containing < 0.005 µL L^-1) or 0.1 µL L^-1 ethylene at 20 °C and 100% RH. The results showed that UV-C treatment delayed skin degreening and reduced endogenous ethylene production compared to untreated control fruit, however these effects reduced over the storage time. As expected, 1-MCP inhibited ethylene production, reduced calyx abscission and retained peel greenness during the storage. Both of the combination treatments, 1-MCP + UV-C and UV-C + 1-MCP reduced endogenous ethylene production and delayed skin yellowing. In all treatments, UV-C and 1-MCP resulted in lower fruit respiration rates than untreated control fruit, however this effect diminished during 7 and 14 days storage for fruits stored in air and 0.1 µL L^-1 ethylene atmosphere, respectively. There was no difference in weight loss, SSC, TA and SSC/TA ratio between the treatments and storage conditions. The results suggest that a pre-storage UV-C treatment, followed by storage at low level of ethylene improves the quality of limes, with the additional improvement when combined with 1-MCP treatment prior or after UV-C irradiation.]]> Mon 14 Jun 2021 18:15:37 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:47830 Fri 23 Jun 2023 12:02:28 AEST ]]>
