1-Methylcyclopropene (1-MCP ) fruit fresh preserver

1-MCP is a very effective inhibitor of ethylene production and ethylene action. As a plant hormone that promotes maturation and senescence, ethylene can be produced by some plants itself, and can exist in a certain amount in the storage environment or even in the air. Only when ethylene is combined with the relevant receptors in the cell can a series of physiology related to maturation be activated. Biochemical reactions accelerate aging and death. l-MCP can also bind well to ethylene receptors, but this combination will not cause mature biochemical reactions. Therefore, before plant endogenous ethylene is produced or exogenous ethylene is applied, it will preemptively apply 1-MCP It binds to ethylene receptors, thereby preventing the binding of ethylene to its receptors, which prolongs the ripening and aging process of fruits and vegetables, and prolongs the fresh-keeping period.

Application situation

Twenty-seven countries and regions have approved the use

On July 17, 2002, the Environmental Agency of the US government allowed it to be used in Apple's commercial storage and transportation, and no residue was detected after the application. The United States Government Environment Agency has exempted the 1-MCP application restrictions. More than 27 countries and regions including the European Union, New Zealand, Australia, the United States, Canada, the United Kingdom, Chile, Argentina, Brazil, Guatemala, Nicaragua, Costa Rica, China, South Africa, Israel, Mexico, Switzerland, and Turkey have approved the use.

New discovery of 1-MCP use

1-MCP has been researched and found that it can be used for spraying of fruits and vegetables before harvesting, and it can also effectively extend the harvest time of fruits and vegetables, extend the shelf life, and make the operation easier; it can also be used for drought and cold resistance in the field to reduce The adverse effects of environmental stress on crops.

 

Used for the preservation of ethylene or ethylene-sensitive fruits, vegetables and flowers.

It can well delay maturity and senescence, maintain the product's hardness, crispness, color, flavor, fragrance and nutrients, effectively maintain the disease resistance of plants, reduce rot caused by microorganisms, and reduce physiological diseases. It can also reduce water evaporation and prevent wilting. The following fruits, vegetables and flowers are treated with this product, and the freshness period is greatly extended. The following is the effect of 1-methylcyclopropene on apple and kiwi fruit.

Apple preservation

-Good to reduce the occurrence of apple tiger skin disease;

-It keeps the color of apples, fresh as ever;

-Maintain the apple flavor very well, sweet and sour;

-It keeps the crispness and moisture content of apples well;

-Significantly extend storage time and shelf life.

Kiwi fruit preservation

-It keeps the hardness of kiwi fruit and prolongs the storage time;

-A good solution to the short shelf life of kiwifruit, expand the transportation radius, and improve market competitiveness;

-Maintain the inner quality of kiwi fruit and reduce the loss of nutrients;

Usage and dosage

The amount of 1-methylcyclopropene used is very small, it is calculated in micrograms, and the method is fumigation. As long as the space is sealed for 6-12 hours and then ventilated, the effect of storage and preservation can be achieved. In particular, the respiration type fruits and vegetables can be fumigated 1-14 days after picking, which can prolong the preservation period by at least twice. Take apples and pears as examples. The preservation period can be changed from the original normal storage months. Extend to 8-9 months. A large number of experiments and production applications have shown that environmentally friendly fresh 1-MCP treated fruits can replace the effect of modified atmosphere. For most apple varieties, the fresh-keeping effect of 1-MCP is generally better than that of modified atmosphere storage. The environmentally friendly freshness is not only effective, but also economical and easy to operate. It is currently the most advanced preservative for extending the storage period and shelf life.

1.Safe, non-toxic and harmless.

2.Easy to use and long-term freshness. 

3.The use cost is low and economical.

4.It can be used in a variety of storage methods, such as air conditioning warehouses, cold storage (cars), simple warehouses, soil warehouses, etc. 

5. It can strongly inhibit apple tiger skin disease and pear black spot. Including production, transportation Export, wholesale, and retail stores can use environmentally friendly fresh to extend the preservation time.

-Using fumigation, the concentration in the air is only 1ppm (parts per million).

Put 1g of 1-MCP and 30ml of water on top of the fruits. Close the exhaust vent and the door of the warehouse for 18-24 hours. It must be more than 24 hours below zero. Then it will be automatically released after opening the door. Ventilating for more than half an hour can keep fruits fresh for more than four months.
