Modified atmosphere packaging and refrigeration of fruits vegetables are used to extend their shelf life. The objective this research was evaluate quality variables in avocado (Persea americana Mill.) cv. "Hass" during storage modified (MAP) at 8 °C contrast them those obtained room temperature (RT) (REF). Fruits physiological maturity were stored MAP bags with a thickness 0.20 mm. A completely...

to determine the effects of pre-harvest salicylic acid (sa) treatments on postharvest life and quality of apricot fruits, four different concentrations (one, 1.5, three and 4.5 mm) were applied six days before harvesting of apricot fruits cv. ‘shamlou’. fruits harvested at commercial maturity stage and stored at 2ºc with 90 percent rh on the same day for a period of three weeks. the fruit was e...

strawberry as a very perishable fruit, is exposed to fungi pathogens especially botrytis cinerea, thus its storage life is very limited. the use of synthetic chemical compounds to control gray mold on strawberry as well as on other fruits that are directly consumed by humans, have become less and less advisable. on the other hand the use of non chemical and safe methods of controlling gray mold...

Nondestructive firmness measurement is critical to assuring postharvest quality and marketability of apples. In this research, two in-house developed sensors (bioyield and spectral scattering) and two commercial sensors (acoustic and visible and shortwave nearinfrared (Vis-SWNIR) spectroscopy), were evaluated for assessing the firmness of apples. Spectral scattering measurements were taken from...

Non-destructive firmness sensors have recently become available for packers and fruit handlers although they demand more information on their performance and reliability. A commercial sensor, aimed both for in-line or bench-top usage, based on low mass impact has been tested on kiwifruit. Correlation between the firmness index given by the device and Magness-Taylor force was low (R 2 = 0.594 an...

The main aim of the present study was the evaluation of proteins and antioxidant potential in ethylene-treated kiwifruit during the first 10 days of ripening. Kiwifruit samples were randomly divided into two groups: treated and untreated. Flesh firmness, sensory value, visual score, free sugars, soluble solids, ethylene biosynthesis, proteins, dietary fibers, total polyphenols and antioxidant p...

In the present study, effects of edible coatings using sodium alginate (SA) and sodium alginate in combination with ascorbic acid (AA) on the shelf-life extension of strawberries at 4±1°C was studied. A factorial experiment was performed based on a randomized complete block design with four replications. The treatments included control (distilled water), SA (1%, 2%, 3% w/v), SA in combination w...

Papayas, rambutans, and Kau oranges were irradiated at 0 (control) and 0.75 (irradiated) kGy and stored for 2 and 9 days to determine the Hect of X-irradiation on objective and sensory quality attributes. Irradiation at 0.25 kGy, as a minimum dose, has been approved as a quarantine treatment for the export of tropicalmts grown in Hawaii. The fleets of irradiation and storage on specific sensory...
