Ice Temperature Or Optimum Temperature Conditions, Fruits And Vegetables High Voltage Electrostatic Preservation

The HVEF (High Voltage Electrostatic Field) experiment apparatus was redesigned. In the conditions of HVEF, controlled temperature, ozone etc. the physiological characters of tomato, strawberry and Chinese date were studied systematically. The following results were obtained: The ripening of tomatoes. strawberries and Chinese dates was delayed in HVEF; The direction of HVEF is an important factor to the preservation of tomatoes----the quality of tomatoes stored in the HVEF with the direction from top to bottom were better than those placed in the same HVEF except the opposite direction, for example, in the conditions of 9 0. 5 C, RH85 95% and treated under 35kv/rn HVEF for 2 hours per day, the respiration peak of tomatoes in the former HVEF appeared 3 days later than the latter the HVEF can alleviate the chilling of tomatoes in low temperature; In controlled temperature preservation, the respiration rate of the fruits and vegetables are decreased greatly; using the controlled temperature, HVEF and MA package together can improve the quality of the stored fruits and vegetables most effectively.
