“…In turn, the rate of respiration results from the interaction of the genetic nature of the produce, its physiological status, temperature and the influence of ethylene, oxygen and carbon dioxide concentrations (Kays, 1997;Wills et al, 1998). A storage life similar to that of fruit held under refrigeration can be achieved at ambient temperature by packing fruit within sealed polyethylene bags, especially with ethylene absorbents such as potassium permanganate (Scott, McGlasson & Roberts, 1970;Chaplin, 1989;Ketsa, Raksritong & Subhadrabandhu, 1992;Ben-Yehoshua et al, 1996;Leena et al, 1997). However, the general usefulness of sealed plastic bags with scrubbers is limited because high temperature can act to adversely influence fruit quality and shelf life through CO 2 levels becoming too high and/or O 2 levels going too low (Kader et al, 1989;Banks, Cleland, Yearsley & Kingsley, 1993;Koolpluksee, Ketsa & Subhadrabandhu, 1993).…”

Experiments were conducted to determine how 1-methylcyclopropene (1-MCP) treatments influence ethylene-stimulated ripening of harvested mango cv. Zihua fruit at 20 o C. The ripening response of fungicide (prochloraz) treated fruit was characterised following various 1-MCP treatments in sealed jars followed by storage in polyethylene bags and/or subsequent ethephon (ethylene) exposure. Exposure of fruit to increasing concentrations of 1-MCP for 12 h resulted in the reduced softening of produce when subsequently held in air for 7 days after ethephon treatment. Application levels of between 1 and 100 ml litre -1 1-MCP had increasing impact, while 200 ml litre -1 1-MCP apparently began to approach response saturation. Exposure of fruit to 50 or 100 ml litre -1 concentrations of 1-MCP for periods from 1 to 24 h subsequently resulted in reduced softening of produce when held in air for 7 days after ethephon treatment. Increasing periods of exposure from 1 to 12 h had increasing impact, while exposure times greater that 12 h appeared to reach saturation. In the absence of ethephon-stimulation, the natural ripening of mangoes held in polyethylene bags was delayed by prior exposure to 100 ml litre -1 1-MCP for 12 h. Extended holding of 1-MCP treated and non-1-MCP treated control fruit in polyethyene bags encouraged physiological and pathological deterioration. Following exposure to 100 ml litre -1 1-MCP for 12 h, mango fruit held for 10 days in polyethylene bags showed a delay in the onset of ripening relative to bagged but non-1-MCP treated control fruit. Treatment with 1-MCP allowed storage of mango fruit in plastic bags at 20 o C for 30 days. Observations suggest that 1-MCP treatments do not adversely influence the quality of the poststorage ethephon-ripened fruit. Thus, application of 1-MCP in combination with the use of polyethylene bags can extend the postharvest life of mango fruit at ambient temperature. Treatments that extend postharvest life are important in developing countries, such as China, where the cold chain infrastructure is often lacking.

“…Transport of the fruit to the laboratory at ambient temperature (15--20 ° C) required another 20 h. On arrival, treatment groups of five replicate fruit were stored in constant-temperature rooms held at 20 and 30°C for 0 (control), 4, 6, 8 and 11 days to simulate a range of postharvest transportation regimes. At the end of each storage period, the gas composition inside the bags was determined by gas chromatography (Scott et al, 1970). The fruit were then transferred to individual gas-tight respiration jars (1.25 1) ventilated with a constant flow of C2H4-free air at 20 ° C, and allowed to ripen.…”

Extending the postharvest life of unrefrigerated avocado (Persea americana Mill.) fruit by storage in polyethylene bags

Mature 'Hass' avocado (Persea americana Mill.) fruit were enclosed in sealed polyethylene bags and stored at ambient temperatures for different times. Modified atmospheres developed inside the bags and fruit stayed firm and apparently non-ripening while they remained enclosed. Storage time and temperature influenced ripening of fruits after they were removed from bags. Most storage treatments resulted in an extension to the total postharvest life of fruits compared to control fruits which were not stored in such bags. Abnormal ripening characteristics were observed when storage temperature was high and storage time exceeded 8 days. INTRODUCTIONThe time taken by harvested mature avocado fruit to become ripe, i.e. soft and edible, is regulated by the interaction between endogenous fruit factors and postharvest environmental conditions. The later in the season that mature fruit are harvested, the less time they take to ripen (Adato and Gazit, 1974b), but the rate of ripening is inversely related to endogenous calcium levels in the fruit (Tingwa and Young, 1974). After harvest, water-deficit stress (Adato and Gazit, 1974a) and treatment with exogenous ethylene (C2H4) (Gazit and Blumenfeld, 1970) accelerates the initiation of ripening, but low temperature causes a marked retardation in ripening rate (Aharoni et al., 1968). Hence, when there is little or no control of the postharvest environmental conditions, the shelf life of avocado fruit becomes difficult to predict and serious problems of marketing may result.Although temperature control is generally regarded as the most effective means of extending the postharvt life of perishable fruit, refrigerated post-0304-4238/81/0000--0000/$02.50

“…The ability of potassium permanganate in reducing the ethylene concentration in the atmosphere around horticultural produce was first demonstrated by Forsyth et al (1967) in apples. It was demonstrated that KMnO 4 retarded the ripening of many fruits (Scott et al 1970;Wills et al 1989).…”

Response of different maturity stages of sapota (Manilkara achras Mill.) cv. Kallipatti to in-package ethylene absorbent

et al. 2011

Sapota fruits are highly perishable due to their climacteric nature. The rapid softening of fruits is primarily due to high activity of many oxidative enzymes and liberation of ethylene. Harvest maturity plays a crucial role in deciding the marketability of climacteric fruits in general. Attempt has been made to evaluate the response of ethylene absorbent on variable maturity groups of harvested Sapota cv. Kallipatti with the objective to delay the ripening during transit and extend its marketability during storage at ambient condition (27-32°C & 65-75% R.H.). Harvested fruits having three different degree of ripeness (as maturity indices viz. mature, half-ripe and ripe) were packed with or without ethylene absorbent sachets (Bioconservación, France) in 10 kg CFB boxes and transported from Dahnu to Delhi covering a distant of approximately 2500 KM by truck on road along with conventional packaging as control. The fruits were evaluated immediately on arrival at Delhi and subsequently during storage for various physical, physiological, biochemical and decay parameters. Mature fruits with ethylene absorbent exhibited maximum delay in ripening, low ethylene liberation, weight loss and high fruit firmness. The response of ethylene absorbent to extend the marketability of ripe fruit was not significant.
