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 (...

Toxicity of ozone gas to conidia of Penicillium digitatum, Penicillium italicum, and Botrytis cinerea and control of gray mold on table grapes

    Penicillium digitatum, Penicillium italicum, and Botrytis cinerea attack fresh fruit and cause significant postharvest decay losses. The toxicity of ozone (O3) gas at different relative humidities to control their conidia was determined. Conidia distributed on cover glasses were...

Application of casein-lipid edible film emulsions to reduce white blush on minimally processed carrots

    White blush on the surface of peeled carrots is a major cosmetic disadvantage in marketing this lightly processed, ready-to-eat product. The loss of quality is exacerbated by surface dehydration. To maintain good appearance, edible coatings consisting of emulsions incorporating...
