electrical properties of fruits are accepted indicators for detecting fruit quality. electrical resistanceone reluctance can detect quality factors and are sensitive to variations in the concentration and stateof water. therefore, these properties can be associated with maturity, damage, overripe condition,decay or other quality factors. in most of previous research on electrical resistance and...

ethylene affects the ripening of fruits and is naturally produced in most plant tissues. its production and accumulation during storage can cause serious damage to stored fruits such as black sweet cherries (cv: takdaneh mashhad). it affects shelf-life and can cause a marked increase in respiration rates, increasing ripening and senescence. in some commodities, accelerated aging and the initiat...

Kinnow (Citrus nobilis × Citrus deliciosa L.) is a widely grown Citrus species known for its high quality fruit juice with good storage life. The present investigation is concerned with the enhancement of shelf-life of Kinnow fruit juice through refrigeration storage and addition of preservatives. Fruit juice was prepared from fruits harvested at complete physiological maturity and potassium me...

apricot is climacteric and its ripening process is regulated by ethylene, therefore, inhibiting ethylene biosynthesis or action should slow the ripening process. this study was conducted to decrease materials losses and increase storage life of fruit by proper packaging. different packaging (polyethylene film, polyethylene film with ethylene absorbent, shrink pack and control) were used. after ...

Irradiation as an alternative quarantine treatment has been under consideration by the International Consultative Group on Food Irradiation. This study was conducted on early and late season ‘Rio Red’ grapefruit to investigate the effects of harvest date, storage, and low dose irradiation on functional constituents, and quality. Fruit was treated with 0, 70, 200, 400 and 700 Gy and then stored ...

Physical and chemical changes in sapote mamey (Pouteria sapota (Jacq.) H.E. Moore and Stearn) fruit during ripening and storage at various temperatures were evaluated. Ripening was associated with flesh softening, an increase in soluble solids content (SSC), and a change in flesh color from yellow or pale pink to a dark pink or red. No changes in fruit skin color or in flesh acidity were observ...

Changes in fruit quality, decay, phenolic and anthocyanin content, and antioxidant capacity of strawberries (Fragaria ananassa Duch. cv. Allstar) stored under air and high oxygen atmospheres at 5 1C were investigated. Freshly harvested strawberries were placed in jars and ventilated continuously with air or with 40, 60, 80, or 100 kPa O2 at 5 1C for up to 14 days. Samples were taken initially, ...

Free radical formation from flavonoids by peroxidase action and changes in flavonoid levels and peroxidase activity during storage were determined to clarify the involvement of naringin radical in chlorophyll (Chl) degradation in stored green Nagato-yuzukichi (Citrus nagato-yuzukichi hort. ex Y. Tanaka) fruit. Chl a was degraded by peroxidase-hydrogen peroxide system not in the presence of hesp...
