Postharvest of Fruit and Vegetables

Chilling Injury of Tropical Horticultural Commodities

  Most tropical horticultural commodities are sensitive to chilling temperatures. Therefore, chilling injury (CI) is a serious problem in the postharvest handling of tropical horticultural commodities. From the standpoint of CI, we can classify all horticultural crops into three categories: A...

Carbon Dioxide-enriched Atmospheres During Cold Storage Limit Losses from Botrytis but Accelerate Rachis Browning of 'Redglobe' Table Grapes

    We evaluated a range of CO2 and O2 concentrations as a potential substitute to SO2 treatments for controlling decay development on ‘Redglobe’ table grape during storage. During the 1998 season, early (14% soluble solids concentration, SSC) and late harvested (17% SSC)...

Effects of Continuous 0.3 ppm Ozone Exposure on Decay Development and Physiological Responses of Peaches and Table Grapes in Cold Storage

    Continuous ozone exposure at 0.3 ppm (v/v) (US-OSHA Threshold Limit Value for short term exposure) inhibited aerial mycelial growth and sporulation on 'Elegant Lady' peaches wound inoculated with Monilia fructicola, Botrytis cinerea, Mucor piriformis, or Penicillium expansum...

Minimum Constant Sulfur Dioxide Emission Rates to Control Gray Mold of Cold-Stored Table Grapes

    Sulfur dioxide generating pads are used worldwide for the control of gray mold, caused by Botrytis cinerea, during long-term cold storage and/or export shipment of table grapes. We propose using an emission rate (measured in µmol SO2 per kilogram of fruit exposed per hour of...

Effect of Ethylene and 1-Methylcyclopropene (1-MCP) on Color and Firmness of Red and Breaker Stage Tomato Stored at Different Temperatures

    The red color of the tomato fruit during ripening is due to the presence lycopene, a compound known for its antioxidant property. This compound is influenced by temperature, ethylene and 1-Methylcyclopropene (1-MCP) treatment. It was believed that ethylene application at chilling...

Manejo Poscosecha de Cebolla Amarilla

El manejo poscosecha de cebolla es muy importante debido a que las perdidas por pudrición pueden llegar a 100% del cultivo. Con un curado y condiciones correctas, se puede almacenar la cebolla sin problemas en poscosecha por 6 a 8 semanas.

Effect of combinations of hot water dips, biological control and controlled atmospheres for control of gray mold on harvested strawberries

  The efficacy of hot water, biological control and controlled atmospheres (CA), alone and in combinations, in controlling gray mold on harvested strawberry fruit was tested. All fruit were wound inoculated with Botrytis cinerea Pers.:Fr. Inoculated fruit were subsequently dipped in hot water...

Influence of pH and NaHCO3 on Effectiveness of Imazalil to Inhibit Germination of Penicillium digitatum and to Control Postharvest Green Mold on Citrus Fruit

  In vitro, spores of Penicillium digitatum germinated without inhibition between pH 4 and 7, but were inhibited at higher pH. Estimated concentrations of imazalil (IMZ) in potato-dextrose broth–Tris that caused 50% reduction in the germination of spores (ED50) of an IMZ-sensitive...

Impact of Postharvest Hot Water or Ethanol Treatment of Table Grapes on Gray Mold Incidence, Quality, and Ethanol Content

  The influence of brief immersion of grape berries in water or ethanol at ambient or higher temperatures on the postharvest incidence of gray mold (caused by Botrytis cinerea) was evaluated. The incidence of gray mold among grape berries that were untreated, or immersed for 1 min in ethanol (...
