In recent years, safer methods for the control of fruit postharvest pathogens have been investigated and heat treatment could represent an effective and safe approach for managing postharvest decay such as Monilinia rots. In the present study, the effect of hot water treatment (HWT) (60◦C for 30 and 60 s) on brown rot was investigated. More specifically, the influence of HWT was determined in i...

application of edible coating as a way of prolonging the shelf-life of perishable fruits and vegetables is promising. two plum cultivars (stanley and giant) were treated with 1% chitosan and then stored at 0-1oc and relative humidity of 90±5% for 40 days. changes in weight loss, respiration rate, fruit firmness, soluble solid content, titrable acidity, ph, ascorbic acid as well as decay rate we...

Economic losses caused by postharvest diseases represent one of the main problems of the citrus industry worldwide. The major diseases affecting citrus are the "green mold" and "blue mold", caused by Penicillium digitatum and P. italicum, respectively. To control them, synthetic fungicides are the most commonly used method. However, often the emergence of resistant strains occurs and their use ...

Incidence of green mold of citrus, caused by Penicillium digitatum, was reduced by 80% or more by the immersion of lemons or oranges for 1–4 min in warm (40.6–43.3°C) ‘liquid lime-sulfur’ (LLS) solution that contained 0.75% (wt vol) calcium polysulfide. The incidence of sour rot, caused by Geotrichum citri-aurantii, was reduced 35–70% by this treatment. LLS was similar in effectiveness to other...

Losses from postharvest fruit diseases range from 1 to 20 percent in the United States, depending on the commodity. The application of fungicides to fruits after harvest to reduce decay has been increasingly curtailed by the development of pathogen resistance to many key fungicides, the lack of replacement fungicides, negative public perception regarding the safety of pesticides and consequent ...

In this research, the antifungal role of hydrogen sulfide (H2S) on the postharvest pathogens Aspergillus niger and Penicillium italicum growing on fruits and under culture conditions on defined media was investigated. Our results show that H2S, released by sodium hydrosulfide (NaHS) effectively reduced the postharvest decay of fruits induced by A. niger and P. italicum. Furthermore, H2S inhibit...

Fruits and vegetables are important source of carbohydrates, proteins, organic acids, vitamins and minerals for human nutrition. When plants or plant parts are used by humans, whether for food, or for aesthetic purpose, there is always a postharvest component. Postharvest losses in fresh fruits and vegetables may occur anywhere from the point where the food has been harvested or gathered up to ...

the effect of different concentration of salicylic acid (0, 1 and 2 mmoll-1) and chitosan (0, 0.5 and 1 percent) on postharvest life and quality of selva strawberry fruit during storage at 2.5±0.5°c with 85-95% rh for 7 and 14 days was studied. decay incidence, marketability, total soluble solids, total acidity, vitamin c content and total antioxidant activity were evaluated during storage. chi...

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...

decline in postharvest losses of kiwifruit depended to maintain of quality characteristics during storage and transportation. storage losses caused serious economic losses in kiwifruit. this study was conducted to inhibition of pathogen infection and increasing fruit quality of kiwifruit. hayward kiwifruits inoculated by b.cinerea conidia through pore wounds which formed by removal of the pedic...
