1-MCP (1-methylcyclopropene) Treatment Protocol for Fruit or Vegetables

引用 收藏 4 提问与回复 分享您的反馈 Cited by


1-MCP (1-methylcyclopropene) is a simple synthetic hydrocarbon molecule that interacts with the ethylene receptor and inhibits the response of fruit or plant to ethylene. 1-MCP has opened new opportunities in handling harvested crops and serves as a powerful tool to learn about plant response to ethylene (Watkins and Miller, 2006). 1-MCP is manufactured by Agrofresh and known by its commercial name SmartfreshSM.

Application of 1-MCP can serve as a powerful tool to examine the response of the plant to ethylene. The commercial production of 1-MCP by Agrofresh allows simple practice of this treatment, especially postharvest. The application of 1-MCP to plants, fruit or vegetable was mentioned in many articles but was not described in detail. This was the motivation to provide the following protocol. In this protocol tomatoes served as candidates for the treatment.

Materials and Reagents

  1. Hand gloves (latex or nitrile)
  2. Rubber septa (for the volumetric flask) (Sigma-Aldrich, catalog number: Z553964 )
  3. Syringe 10 ml (OMG, catalog number: OMG-W-10M )
  4. Needle 0.60 x 30 mm (Pic, catalog number: 03.070140.300.800 )
  5. Weighing papers for the 1-MCP powder (Whatman, catalog number: 28414662 )
  6. Freshly harvested tomatoes (any type and origin)
  7. 1-MCP powder (Agrofresh Inc.) containing 0.14% 1-MCP as active ingredient
  8. Tap water


  1. 30 L airtight HDPE plastic barrel wide mouth and cover with lid equipped with flexible latex hose or rubber septa (Chen Samuel chemicals, catalog number: 0100230 )
  2. Brand volumetric flask 1,000 ml (Sigma-Aldrich, catalog number: Z326828 )
  3. Benchtop weight scales with 0.01 g resolution (Vibra, catalog number: AJ-3200CE )


  1. Preparation of 1-MCP gas stock (1,000 ppm or 0.1%)
    1. Gently pour 0.82 g of 1-MCP powder into the 1,000 ml volumetric flask and close tightly with the rubber septa.
    2. Inject a volume of 50 ml of water into the closed flask (5 times, 10 ml of water) and dissolve the powder to release the 1-MCP gas (Figure 1A).
    3. Turn the volumetric flask upside down to check that the gas volume is 1,000 ml otherwise add water up to the marked line (Figure 1B).

      Figure 1. Preparation of 1-MCP gas stock and application to the tomato fruit. A. Injection of water into the volumetric flask through the rubber septa; B. Volumetric flask filled with water up to the marked line to allow accurate volume of gas; C. Injection of 1-MCP gas through flexible latex hose into the closed barrel with tomatoes inside (Pictures: Dan Gamrasni).

  2. 1-MCP treatment.
    1. Place the tomatoes (It is recommended not to exceed over one third of the barrel volume) inside the barrel and close the lid tightly. You can use wrapped plastic or other solution to prevent any gas leakage. The tomatoes and the barrel should be placed in a 20-25 °C room.
    2. To apply 1 ppm of 1-MCP: injection of 30 ml of 1,000 ppm 1-MCP in 30 L barrel will give a concentration of 1 ppm 1-MCP to the tomatoes.

      C1 x V1 = C2 x V2; 1,000 (ppm) x V1 (ml) = 1 (ppm) x 30,000 (ml)

      Where, C1 = the concentration of 1-MCP gas stock in the volumetric flask (ppm); V1 = the unknown volume of the 1-MCP gas stock sample that should inject into the Barrel (ml); C2 = the wanted concentration of 1-MCP in the barrel (ppm); V2 = the volume of the barrel (ml).
    3. The application of 1-MCP: Inject 10 ml of water into the volumetric flask (1-MCP) through the septa, draw up 10 ml of 1-MCP gas and inject immediately into the closed barrel through the flexible latex hose or the septa (Figure 1C).
    4. Repeat step 2c two more times until injecting a total of 30 ml 1-MCP gas into the barrel.
    5. Incubate for 24 h.
    6. Open the barrel and air the tomatoes for at least 2 h to allow the tomatoes to adjust to the atmospheric environment. It is possible to measure ethylene levels and/or carbon dioxide in the barrel before opening.
    7. As a control, untreated tomatoes should be placed in similar conditions without 1-MCP or any other gas treatment (Figure 2).

      Figure 2. The effect of 1-MCP treatment on the color change of tomatoes (Lycopersicon esculentum cv. Ailsa Craig) harvested at different ripening stages (mature green, breaker or early orange) 48 h after the end of the treatment (Picture: Dario Breitel)


  1. The volume of the tomatoes should not exceed one third of the barrel to prevent CO2 accumulation if quicklime is not available, otherwise use bigger barrel (200 L) or do the treatment to smaller samples of tomatoes in few barrels.
  2. To prevent carbon dioxide accumulation due to fruit respiration in the closed barrel, it is possible to add 0.5 kg of quicklime (known as burnt lime) that will spontaneously react with CO2 from the air (you can keep this powder in any paper bag).
  3. It is possible to use the 1-MCP stock solution up to 2 weeks keeping the volumetric flask upside down at low temperature (4 °C).


The protocol was adapted from Gamrasni et al. (2010), and was similarly applied in Breitel et al. (2016).
We would like to thank RIMI and Agrofresh Inc. for the supply of 1-MCP.

1-MCP(1-甲基环丙烯)是与乙烯受体相互作用并抑制果实或植物对乙烯的反应的简单合成烃分子。 1-MCP已经为处理收获的作物开辟了新的机会,并且是了解植物对乙烯的反应的有力工具(Watkins和Miller,2006)。 1-MCP由Agrofresh制造,以商业名称Smartfresh SM 而闻名。

背景 1-MCP的应用可以作为检测工厂对乙烯的响应的有力工具。 Agrofresh的1-MCP的商业化生产允许这种处理的简单实践,特别是收获后。 许多文章中提到了1-MCP对植物,水果或蔬菜的应用,但没有详细描述。 这是提供以下协议的动机。 在这个协议中,西红柿作为治疗的候选人。

    1. 轻轻地将0.82g 1-MCP粉末倒入1,000ml容量瓶中,并用橡胶隔片紧密地紧贴。
    2. 将50ml体积的水注入封闭的烧瓶中(5次,10ml水),并溶解粉末以释放1-MCP气体(图1A)。
    3. 将容量瓶倒置倒置,以检查气体体积为1,000 ml,否则将水加至标线(图1B)。

  2. 1-MCP治疗。
    1. 在桶内放置西红柿(建议不要超过桶体积的三分之一以上),并将盖子紧紧关闭。您可以使用包裹的塑料或其他溶液来防止任何气体泄漏。西红柿和桶应放在20-25°C的房间。
    2. 应用1ppm的1-MCP:在30L桶中注入30ml的1,000ppm的1-MCP,将给番茄1ppm的1-MCP浓度。

      C1×V1 = C2×V2; 1,000(ppm)×V1(ml)= 1(ppm)×30,000(ml)

      其中C1 =容量瓶中1-MCP气体的浓度(ppm); V1 =应注入桶(ml)的1-MCP气体样品的未知体积; C2 =桶中1-MCP的需要浓度(ppm); V2 =桶的体积(ml)。

  1. 如果生石灰不可用,番茄的体积不应超过桶的三分之一,以防止二氧化碳积累,否则使用较大的桶(200升),或少量处理较小的番茄样本桶。
  2. 为了防止封闭桶内水果呼吸引起的二氧化碳积聚,可以添加0.5公斤的生石灰(称为生石灰),这些生石灰会与空气中的CO 2自发反应(您可以保持这一点任何纸袋中的粉末)
  3. 可以使用1-MCP储存溶液长达2周,使容量瓶在低温(4°C)下倒置。

You should do similar to the protocol,
However apply 100 mL of 1-MCP gas instead of 30 mL as mentioned in procedure section 2b if you need 1 ppm.

Good Luck!

Dear Authors,
Although, it was in preliminary experiment, I used, in a rather conclusive way this protocol without any modifications.
