Effect of Palletized Map Storage on the Quality and Nutritional Compounds of the Japanese Plum cv. Angeleno (Prunus salicina Lindl.)
The influence of active modified atmosphere packaging MAP (10.0 kPa of O2 and 5 kPa of CO2) on palletized system was evaluated to extend the marketability of fresh plums cv. Angeleno. Fruits were wrapped with a polyethylene film in pallet bag units at 1C and 90% relative humidity for up to 60 days. The gas values of the pallet bags, the fruit weight losses and their qualitative and nutraceutical characteristics were periodically monitored to evaluate the goodness of storage. The results showed as the pallet bag have maintained the market life of Angeleno plums to up to 60 days, preserving the most important qualitative traits of fruits. After 20, 40 and 60 days the MAP treatment maintained …
Effect of surround WP (a Kaolin-based particle film) on Ceratitis capitata infestation, quality and postharvest behavior of cactus pear fruit cv Gialla
ABSTRACT A Kaolin-particle film (Surround WP) was applied at 3% to cactus pear (Opuntia ficus-indica cv Gialla) to assess its capacity to Control medfly (Ceratitis capitata Wiedemann) infestation and to evaluate its effects on the quality and postharvest behavior of treated fruit. In the first trial, Kaolin was applied at the end of July when fruit were green and about two weeks later, at color breakage. Its efficacy was compared with a standard organophosphate insecticide (Phosmet). The experiment was conducted in two locations in 2014 and 2015. Kaolin application was very effective in preventing medfly attacks until natural fruit drop in November. Kaolin treated fruit were harvested at th…
Increasing Cold Tolerance of Cactus Pear Fruit by High-Temperature Conditioning and Film Wrapping
Pre-storage high-temperature conditioning (HTC, 38 °C, and 95% RH for 24 h) and individual film wrapping (IFW) with a perforated polyolefinic heat-shrinkable film were used as individual treatments or in combination to mitigate chilling injury of first crop cactus pear cv âGiallaâ. The fruit was stored for 21 days at either 2 or 8 °C (CS) plus 1 week of simulated marketing conditions (SMC) at 20 °C. The reduction in peel disorders and decay in HTC-treated fruit stored at 2 °C was comparable to that detected in control fruit stored at 8 °C. IFW was more efficient than HTC in reducing peel disorders, almost completely inhibited weight loss, and preserved freshness in fruit st…
Reducing postharvest decay in cactus pears by dip treatment with imazalil or azoxystrobin
Postharvest decay in cactus pear is a minor problem in fruit marketed directly after harvest, while it may represent a major cause of losses when fruit are cold stored or subjected to cold quarantine treatments. Unfortunately, to date, no postharvest fungicide has been registered to control postharvest decay of cactus pears. Thus, the objective of this study was to evaluate the efficacy of two globally known fungicides, imazalil (IMZ) and azoxystrobin (AZO), registered for postharvest treatment of various fresh produce species, to control decay on cactus pears. Second-crop cactus pears ‘Gialla’ fruits were dipped in 500 mg L(‑1) IMZ or AZO and stored at 1 or 8°C and 90-95% RH for 2 or 3 wee…
