Product Detail

Product Tags


1-MCP is used as ethylene-sensitive Fruit, vegetable and flowers antistaling agent. It not only can significantly reduce the respiration of fruit and vegetables, flowers ,but also keep the product hardness, brittleness, color, flavor, aroma and nutrients, so 1-MCP can delay ripening and senescence, Meanwhile it also can effectively enhance the disease resistance, reduce the decay and alleviate the physiological diseases.The appearance of 1-MCP is regarded as a revolution in the field of preservation in the world.

1-Methylcyclopropene (1-MCP) is an ethylene action inhibitor in plant cells; it binds with the receptor. As a result of this it can reduce autocatalytic ethylene production. It has been used to enhance the postharvest life of fresh fruits and vegetables including in combination with ULO storage.


First step:
-Put it in 1% alkaline solution, such as 1% NaOH solution.
-Rate: 1g of 1-MCP in 40-60ml of 1% NaOH solution.
-Remark: we use NaOH solution instead of water, as when the tempreture is lower than 0℃ in storage, water will freeze and can not work.

Second step:
-When soluted, the 1-MCP will automatically release into the air.
And the crops are surrounded with 1-MCP mixed air. It is so called “fumigation”, or technically called 1-MCP treatment.
-Remark: In order to have a thorough and successful result, a air-sealed space is required.

-1g of 1-MCP powder can be used in the room of 15 cubic meter.
-Divide the solution in different place of storage can let 1-MCP spread adequately.
-Put solution in the position which higher than crops.
