Ethylene Control in the distribution Chain of non-Climateric Fresh Produce
A scientific study carried out in Australia by the prestigious professor of post-harvest, Dr R.B.H. Wills, has concluded that most non-climacteric fresh produce is kept in the distribution chain in atmospheres with an ethylene level that causes losses of between 10% and 30% of their potential post-harvest life. During the study more than 700 measurements were made of the ethylene level in the ...

Ethylene removal in Pears
The Conference pear has a greenish skin with brown marks and a consistent greenish-white pulp. It is a widely grown and consumed variety in Europe. It can be stored for up to 9 months in controlled atmosphere conditions in refrigeration chambers, a period in which the effect of ethylene on the fruit can lead to a major loss of quality. Ethylene accelerates the ripening and senescence of the ...

Study of visual, sensorial and physicochemical characteristics of Tommy Atkins mangoes submitted to ionising radiation as a method of postharvest conservation
With the objective of evaluating the effect of ionising radiation on the main characteristics of postharvest quality of mangoes (Mangifera indica L), fruit of Tommy Atkins cultivar have been irradiated with gamma rays from a cobalt-60 source. Doses of 200, 400 and 600 Gy were applied, and non-irradiated fruit served as control. After being stored for 15 days at 11.5?C, to simulate transport ...

NIR Vs. Penetrometer to judge produce quality
Though firmness has been popularly used to assess the quality of fruit, fruit dry matter is now increasingly being used instead. It is necessary to understand both traits to find the reason behind this shift in preference. Dry Matter When water is removed from produce, what is left are the solids, or the dry matter. The dry matter (DM) of plants is made up of many soluble compounds, called the ...

Effect of exogenous putrescine treatment on the quality and storage life of peach (Prunus persicaL.) fruit
The effect of various concentrations of diamine putrescine (0, 0.5, 1, 2, 3 and 4 mM) on the quality and storage life of peach (Prunus persica L. cv. Zaafarani) fruit was evaluated during storage at 2°C. Treatments were performed immediately after harvest. Flesh firmness, soluble solids content, titratable acidity, pH, weight loss and ethylene emission were determined on treated and untreated ...

Chilling injury as an indicator of critical temperature for cold storage of guava (Psidium guajava L.) cv. Allahabad Safeda
The critical temperature for cold storage of guava cutivar Allahabad Safeda and the changes in physico-chemical attributes during its storage were studied. Fruits were stored at 5, 8 and 15° C with 85–90% relative humidity and withdrawn weekly from cold storage and kept at ambient condition (18–20° C and 65–70% RH) for analysis. Chilling Injury (CI) symptoms, characterised by browning of peel, ...

Application of essential oils for postharvest control of stem end rot of mango fruits during storage
During screening of 14 essential oils against Botryodiplodia theobromae, geranium, mint, palmarosa, and thyme oils were found to exhibit absolute fungitoxic activity. The oils were subsequently standardised through physicochemical and fungitoxic properties. The minimum inhibitory concentration (MIC) of geranium, mint, palmarosa and thyme oil was found to be 200, 100, 100 and 50 ppm respectively. ...

Characteristics of postharvest quality in regional fruits treated with ionising radiation
Quality postharvest of three cultivated species of the Northeast Region of Brazil was evaluated after receiving ionising radiation. Cashew peduncles (Anacardium occidentale L. var. Nanum) stored for 14 days under 6.5°C had presented best results in the sensorial analyses for external appearance, flavour and aroma when irradiated with 1 kGy. Sapodillas (Manilkara sapodilla (L) Van Roy en) ...

Effect of calcium dips combined with mild heating on postharvest life and quality of strawberry
The effect of calcium dips combined with mild heat treatment on quality and postharvest life of strawberries (cv. BARI strawberry–1) was studied. Immediately after harvest, strawberries were treated by dipping in distilled water, CaCl2 solutions at 1%, 2% and 3% for 15 min at 45°C and left untreated. Subsequently, the fruits were stored at 10°C with 80 ± 5% RH for 8 days. The effectiveness of the ...

Physicochemical monitoring of minimally processed pineapple with the use of edible films based on maltodextrin
Minimally processed products have become more important in the marketing of fruits and vegetables due to increasing consumer demand for convenience and nutritional benefits. The successful use of this technology depends on storage and appropriate treatment. This work aims to assess the quality of a variety of pineapple produced in Santa Isabel do Ivaí/PR/Brazil, noting the application of a ...

Influence of aqueous 1–methylcyclopropene on postharvest ripening and quality of banana
The influence of aqueous 1–methylcyclopropene (1–MCP) on the ripening of harvested banana fruit cv. 'Cavendish' was investigated. Banana fruit at mature green stage were dipped in aqueous 1–MCP at 100, 200, 400 and 600 µg L−1 for 10 min, fan–forced air–dried and then stored at 20 ± 2°C and 85–90% RH for ripening over 30 days. Banana ripening was delayed when dipped in 100–600 µg L−1, however; ...

Ethylene removal by chemisorption. Postharvest technology for kiwi
Abstract Iran ranks seventh in the world for kiwi production, with over 3200 MT produced in 2012. Kiwifruit can be stored for over 6 months under appropriate conditions, but fruit softening and fruit rots (Botrytis cinerea) can cause severe losses during cold storage, transit, distribution and retail. Kiwifruit is a climacteric fruit very sensitive even at very low concentrations of ethylene ...
