the objective of this study was to evaluate the storage life and quality of persimmon (diospyros kaki thunb.) fruit cv. ‘karaj’ stored at 0°c for 4 months after postharvest calcium chloride treatment. fruit weight loss, fruit firmness, total soluble solids, titratable acidity, total phenolic content, soluble tannin content, chilling injury, antioxidant activity, electrolyte leakage, and malondi...

leaf analysis is a general method of estimating the fertilizer needs in fruit trees, but there exists a limited correlation between it and fruit quality. throughout the present study, fruits were harvested 10 weeks following full bloom and at the commercial maturity (6.2 brix) stages from thirteen different commercial kiwifruit orchards that had been fertilized with different fertilizers, the e...

The efficacy of an edible chitosan coating (CHI; 4 mg/mL) and Origanum vulgare L. essential oil (OVEO; 1.25 μL/mL) for maintaining the quality of cherry tomato fruit during storage at room (25°C; 12 days) and cold (12°C; 24 days) temperatures was assessed. CHI and OVEO in combination showed in vitro fungicidal effects against R. stolonifer and Aspergillus niger. CHI-OVEO coating reduced the inc...

in order to study fruit  quality changes in apple cultivar gala, related to ripening stage and storage time, an experiment was conducted in a split plot arrangement in randomized complete block design with four replicationsin the area of damavand– jaban for three years. five levels of sampling times in storage were assigned to main plots, and three levels of harvesting times were randomized in ...

BACKGROUND The Chinese bayberry (Myrica rubra Sieb. and Zucc.) is a subtropical fruit native to China, with unique flavor, sweet and sour taste, and high nutrition and health values. The fruit is highly perishable and susceptible to mechanical injury, physiological deterioration and fungal decay once harvested. This study was to investigate the effect of hypobaric storage on the quality of Chin...

abstract the effect of different levels of potassium permangenate (kmno4) on quality of mango fruits were studied over a period of 21 days. a factorial trial in the form of complete randomized design as three levels of kmno4 (0, 5 or 10 g. kg-1 fruit) and three time period (7, 14 or 21 days) was used. means were compared using duncan’s test (p< 0.05). compositional parameters (ph, acidity, tota...

Detailed Accomplishments in 2008-09: Processors are concerned about peel integrity of CMNP-treated fruit. We conducted 2 trials in March and April with Valencia oranges to determine the postharvest effect of CMNP applied to canopies for the purpose of loosening fruit on fruit crush force, peel puncture resistance, and peel puncture depth. Fruit were collected during our harvesting trial studies...

The postharvest quality of raspberries (Rubus idaeus L.) was evaluated after treatment with several natural volatile compounds and storage at 0, 10 or 20 C. At high storage temperature (20 C), raspberries deteriorated rapidly and none of the natural volatile compounds that were used were effective in extending storage life of the fruit. At low storage temperature (0 C), little difference could ...
