“…Monthly measurements showed a systematic decrease in TA at a rate dependent on the storage conditions and 1-MCP treatment. This corresponds with the findings by Hedges et al [23], who additionally pointed to the harvest date as a factor affecting TA as a harvest delay resulted in a visible decrease in its initial value. What deserves mentioning as regards our study is the weather conditions prevailing during the growing season because the initial TA values measured at the optimal harvest date varied between years.…”

“…Another method used in recent years to improve storability is to use substances that limit ethylene production in climacteric fruit [22]. One of such substances is 1-methylcyclopropene (1-MCP), which has been used for nearly two decades [23]. In both NA and CA cold storage, 1-MCP can be applied to maintain the quality attributes of fruit, especially firmness.…”

Late pear cultivars, such as ‘Conference’, can be stored for a long period, with their storability depending on storage conditions. A three-year study (2011-2013) compared the impact of half-year storage using four technologies – normal atmosphere, normal atmosphere + 1-methylcyclopropene (1-MCP), controlled atmosphere, controlled atmosphere + 1-MCP – on the quality parameters of ‘Conference’ pears, such as mass loss, firmness, total soluble solids, acidity, antioxidant capacity, and the incidence of diseases and disorders. Additionally, the study analysed different storage conditions in terms of profitability, based on the market prices for pears in the seasons during which the pears were stored. The storage conditions had a very strong influence on the fruit quality parameters, and was found to affect most visibly the mass loss and the incidence of postharvest diseases and disorders. The storage of ‘Conference’ pears for 180 days in normal atmosphere is not economically viable, even if the fruit is subjected to 1-MCP treatment.

“…Pear aroma, which is one of the most important attributes to consumer acceptance, has been shown to be influenced by storage conditions and postharvest treatments [ 19 , 20 , 21 , 22 ]. The volatile organic compounds (VOCs) that contribute to the fruit aroma are generated through metabolic pathways during ripening, harvest, postharvest, and storage and vary according to the cultivar [ 23 ].…”

Although new storage technologies have been emerging in recent years, preservation of pear (Pyrus communis L.) remains a challenge for suppliers. Maintenance of desired organoleptic properties throughout cold storage using non-chemical strategies has been investigated and the use of edible coatings has shown potential to delay fruit quality deterioration during cold storage. Thus, the objective of this study is to evaluate the impact of pectin coatings including plant extracts, in “Rocha” pear (Pyrus communis L. cv. Rocha) preservation. A four-month pilot scale assay was performed in both dynamic controlled atmosphere (DCA) (−0.5 °C, 0.5% O2, and 0.4% CO2) and normal atmospheric (NA) conditions (2 °C). For each storage condition, the following three coatings were tested: pectin (3% w/v) (PCT), pectin (3% w/v) + strawberry tree leaves extract (9.5 mg/mL) (CT1), and pectin (3% w/v) + apple pomace extract (16 mg/mL) (CT2). Volatile compounds, potentially related to aroma or ripening status of “Rocha” pear, were monitored alongside with conjugated trienols (CTs) and maturity parameters. The combination of DCA conditions and the application of pectin coatings were able to reduce the release of Rocha pear volatiles associated with ripening status, (particularly esters and sesquiterpenes), as well as reduce CTs, which could contribute to the preservation of Rocha pear for longer periods.

“…The ability of 1‐MCP to delay the softening of climacteric fruit is affected by harvest maturity (Mir, Curell, Khan, Whitaker, & Beaudry, ; Wang & Sugar, ; Watkins, ). Early harvested “Golden Delicious” apples are more sensitive to 1‐MCP (Gago et al, ) and this is also the case for “Conference” and “Alexander” Lucas pears (Hendges et al, ). In contrast, Guillén et al () suggested that the efficacy of 1‐MCP on higher maturity is more effective than lower maturity in tomato fruit.…”

Maturity, storage temperature, and postharvest treatment are all important factors that determine how postharvest storage affects qualities that make peaches attractive to consumers. In this study, the combined effects of maturity stage (as determined by I AD value; M1: 1.0 ~ 1.4, M2: 0.6 ~ 1.0 and M3: 0.2 ~ 0.6), treatment with or without 1-methylcyclopropene (1-MCP), and storage at different temperatures (5°C, 10°C, and 20°C) were measured in "Hujingmilu" peaches. Our results showed that treatment with 1-MCP helps to maintain fruit postharvest quality, but efficacy is influenced by postharvest factors. Principal component analysis (PCA) showed that1-MCP application increases the storage potential of fruit and has the potential to make fruit harvested at middle maturity (M2) more acceptable to consumers. In addition, low maturity fruit (M1) treated with 1-MCP are more suitable for long-term transportation in cold storage. Practical applicationsThis study investigated the effects of different temperatures and different maturities on 1-MCP-treated peach fruit and provided postharvest strategies for peaches in different commercial demands. This work will help to extend the storage life and expand the sales area of peach fruit and increase the industrial income.
