Fruits are supposed to be a part of our daily meals. To test chemically calcium carbide when reacts with water to produce acetylene gas. An important news that flashes during the mango seasons in television is that the fruit markets contain artificially ripened fruits which is extremely hazardous to health. When Calcium Carbide comes to contact with moisture, it reacts to give acetylene which has ethylene responsible for ripening of fruits. Learn how your comment data is processed. In developed countries of the world, there are safe and acceptable methods to hasten the ripening of fruits and until Nigeria’s enforcement agencies can clamp down on those who continuously use unsafe methods to ripen our fruits and generally ensure safety of our foods, it is our duty to protect ourselves and our families the best way we can. ). In pineapple plantations, a few granules of calcium carbide was dropped onto the growing point of the pineapple plants, which promoted even and uniform flowering. Among all these, most commonly used ripening agent is calcium carbide but its use is discouraged due to its health hazards effects as it contains traces of phosphorus and arsenic. Market is filled with artificially ripened mangoes that pose a possible health hazard. Taste test The use of Calcium carbide in ripening fruits has been banned in many countries of the world and the government as well as responsible citizens need to sensitize the public as well as fruit merchants about the dangers of this chemical. When the fruit reaches maturity, it starts producing ethylene gas, along with slowly breaking down acids in the fruit, and converting starch into sugar. How can one detect if calcium carbide has been used to ripen fruits? I also read that if you cut the pulp of fruits that are artificially ripened and put them in a cup of water, they will float compared to the naturally ripened fruits that will sinks. Chemicals like calcium carbide / ethephon and oxytocin are reportedly being used in fruit and vegetable mandis / farms for artificial ripening of fruits and for increasing the size of fruits and vegetables respectively. Naturally ripened fruits or fruits ripened using ethylene weigh more and are more juicy; whereas fruits ripened using calcium carbide weigh less, and are dry and less juicy. *** Trader/ Farmers prefer the use of CaC2 to ripen the fruits as the cost of 1Kg of CaC2 (Industrial Grade, IG) is about 50 tk and it can ripen 10 tones of fruits. Washing and peeling the fruits before eating can minimise the risks of calcium carbide. Fruit therefore should promote health always. No change in colour of the solution indicates that calcium carbide was not used for ripening the fruit, Fruits (mango) ripened artificially with CaC, If a lit match stick is hold near a fruit (remember not near to boxes/ containers/cartons of fruits) artificially ripened with CaC, In case of banana and papaya, if the fruits are ripened by CaC, The present of arsenic in fruits (the origin of As in fruits is due to ***Industrial Grade (IG) of CaC, It is not advisable to buy fruits when they arrive in market before the due period or during off season, It is advised to wash fruits under running salt mixed water for 10 minutes, It is better to cut into pieces rather than consuming them directly, Instead of salt mixed water, one can use apple cider vinegar or normal vinegar. The reason for this is because Cac2 when mixed with moisture or water gives off acetylene gas and traces of phosphorus and arsenic which are hamful to man when consumed. If you find any fruits appearing to be force-ripened, you should decide not to eat them. In the developed world, food business has evolved such that ethylene gas (which is acceptable in some countries) is used artificially to speed up ripening.
