why ethylene gas to make the fruit matures faster?

From the research results are as follows: bananas are ripened with carbide fastest (less than three days) maturation, but also the fastest pembusukannya.
Then, according to experts from the Post Harvest Unbraw:
Banana and a kind, mature processes proceed naturally chemically. Carbohydrates in the womb flesh turned into glucose, which makes the sweetness and softened.
The process produces gases Ethylene. This gas molecules propagate from one to the other makes around so mature.
This is the basis to give Calcium Carbide (Calcium Carbide), is used to assist the process of maturation.
Calcium carbide, carbide we call it, when in contact with water or moisture will produce acetylene gas. Gas is its chemical structure is similar to the natural Ethylene. Because it is filled with acetylene gas, the fruit will ripen simultaneously ferment. Yes, if less ripe fruit will not mature as nicely, because the content of carbohydrates – starch substance is still lacking. Acetylene gas as the light would fly and mixed with air.
Dangers posed as yet no real evidence, everything is just based on assumption without scientific evidence.
Ripening fruit in this way are healthier than used Liquid Chemicals Ethylene containing the bercamour phosphorus. Phosphorous mixture ternmasuk highly toxic, besides its application by spraying rub the fruit.
What is Calcium Carbide (Carbide)?
Calcium carbide or carbide is a chemical compound with chemical formula CaC2. Carbide is used in carbide welding process and also to accelerate the maturation of the fruit.
reaction of Calcium Carbide with water is
CaC2 + 2 H2O → C2H2 + Ca(OH)2
Therefore 1 gram CaC2 produces acetylene 349ml. In the process of carbide welding, acetylene is then burned to generate the heat required in welding.
Ethylene gas
carbide has long been used traditionally to stimulate fruit maturity. Its effectiveness is only one hundredth than ethylene. Who knew that in addition to hyper maturity, acetylene gas produced from calcium carbide is also useful to eliminate green. Ethylene is an unsaturated hydrocarbon compound at room temperature is a gas. Ethylene can be produced by a living plant tissues, at certain times of these compounds can cause significant changes in the process of growth and maturation of agricultural products.
Ethylene is a gas plant life can be classified as an active hormone in the maturation process. Called hormone because it can meet the requirements of the hormone, which is produced by plants, is the car in plant tissues and is an organic compound. Unconsciously, the use of ethylene in the maturation process was long, long before it was known the name of the compound and its role Although there is now sufficient evidence to support the view that convincing C2H4 (ethylene) was actually a ripening hormone, but the study found some difficulties, such as: far people have not managed to eliminate all the C2H4 (ethylene) is in jarigan to show that the maturation process will be delayed if C2H4 (ethylene) no. Attempts to reveal or learn more about the biogenesis of ethylene formation continues with research initiated by scholars, this time with memenfaatkan research ethylene itself with typical activity on the network some fruits are likely to be able to explain a question mark related to the formation biogenesis. Ethylene is produced by higher plants from the essential amino acid methionine in all plant tissues. Production of ethylene depends on the type of tissue, species, and stage of development [9]. Ethylene is formed from methionine via the 3 processes [10]:
• ATP is an important component in the synthesis of ethylene. ATP and water will make methionine lost 3 phosphate groups.
• 1-Amino-1-carboxylic aminosiklopropana synthase (ACC synthase) and facilitates the production of ACC and SAM (S-adenosil methionine).
• Oxygen required to oxidize ACC and ethylene production. This reaction is catalyzed using ethylene-forming enzyme.
Today the research that focuses on the effects of fruit ripening. ACC synthase enzymes in tomatoes to be manipulated through biotechnology to slow ripening of the fruit so that the flavor is maintained.
Ethylene is a colorless liquid, viscous and sweet, easily soluble in water, has a relatively high boiling point and low freezing point. These compounds are commonly used as a solvent and material softener (softener). In agriculture ethylene is used as an astringent fruit cooking. Ethylene is a growth hormone which is generally different from auxin, and cytokinin griberelin. Under normal circumstances, a gaseous ethylene and its chemical structure is very simple. Ethylene in nature will take effect if the physiological changes in the plant. This hormone plays a role in fruit ripening phase klimaterik.
Treatment of mangoes using ethylene at different concentrations will affect the process of fruit ripening. Fruit ripening is seen by the structure of yellow, soft fruit and flavor. Speed ripening fruit grown there are substances encourages solving hoarding flour and sugar. The process of solving the flour and sugar accumulation is a cooking process that is characterized by changes in color, texture and smell of the fruit.
The process of protein synthesis occurs in the maturation process of natural or hormonal glance, where the protein is synthesized as soon as the process of maturation. Fruit ripening and inhibited by protein synthesis in the early phase siklohexamin klimatoris after siklohexamin missing, then the synthesis of ethylene not have problems. Synthesis of ribonucleic also required in the process of maturation. Ethylene enhances the synthesis of RNA on a green mango.
Ethylene can also be formed by the activity of auxin and ethylene able to eliminate the activity of auxin as ethylene can damage cell polarity transport, on condition of formation of ethylene anearob hampered, in addition to O2 temperature also affects the formation of ethylene. Ethylene formation rate decreases at temperatures above 30 0 C and stopped at a temperature of 40 0 C, so that the mass storage of the fruit with anaerobic conditions would stimulate the formation of ethylene by the fruit. Ethylene produced by the cumulative effect of each fruit and fruit stimulate others to mature faster.
Fruit based content amilumnya, divided into fruit and fruit klimaterik nonklimaterik. Klimaterik fruit is a fruit that contains a lot of starch, such as banana, mango, apple and avocado ripeness can be stimulated by ethylene. Endogenous ethylene produced by the fruit that has been cooked by itself can stimulate the maturation of the fruit bunch brooded. The fruit is a fruit that contains nonklimaterik amilumnya few, such as oranges, grapes, watermelon and pineapple. Provision of ethylene on the type of fruit can stimulate respiration rate, but can not stimulate endogenous ethylene production and ripening fruit.
Klimaterik and fruit ripening process due to chemical changes in the activity of the enzyme pyruvate dekanoksilase causing keanaikan amount of acetaldehyde and ethanol that increased CO2 production. Ethylene produced in ripening mangoes will increase respirasinya process. Stage where mangoes are still in good condition if some of the contents of cells that comprise the vacuole.
Physiological changes that occur sealam maturation process is the process of respiration kliamterik,

One comment on “why ethylene gas to make the fruit matures faster?

  1. besides hyper maturity, acetylene gas produced from calcium carbide is also useful to eliminate green. and this is the stage of fruit ripening quickly, which brings advantages especially farmers. is there any negative impact caused by the use of ethylene gas is? . explain!
