Usually fruits produce ethylene gas, a plant hormone, naturally that ripens the fruits. Artificial ripening of fruits causes cancer, liver, kidney diseases – Experts September 19, 2018 0 Medical and health experts have warned Nigerians against using chemicals to ripen fruits, saying substances like carbide are responsible for the rising cases of liver, kidney and cancer in the country. The Industrial-grade calcium carbide, popularly known as “masala” is often used by some unscrupulous traders to release acetylene gas for artificial ripening of fruits like mango, banana, papaya, etc. However, the organoleptic properties of the fruits i.e. Natural fruit ripening is a combination of physiological, biochemical, and molecular … As per FSSAI artificial ripening of fruits by acetylene (carbide) is banned and only ethylene can be used at a concentration up to 100µl/L depending upon the crop variety and maturity level of fruits. D. Ethylene. Artificial ripening of mangoes using calcium carbide was the important fact that was being displayed in the news. Sources of Ethylene Gas: Ethylene gas obtained through the following systems may be used for artificial ripening of fruits: Protocol for application of Ethylene gas from various sources. RIPENING Ripening is the final stage of development of a fruit which involves series of physiological and biochemical events leading to changes in colour, flavour, aroma and texture that make the fruits both attractive and tasty. Published: July 25, 2019. The maximum concentration of ethylene gas generated will be 100 ppm. The fruits are ripened at the destination markets before retailing and hence artificial ripening has become essential. Calcium carbide, when hydrolysed, produces acetylene, which causes artificial ripening of fruits. In artificial ripening, this process is mimicked using chemicals. 2. Table 1 Requirements of exposure time and ripening temperature for different fruits. It is said to have the same effect as ethylene the natural ripening hormone. Climacteric fruits continue ripening after being picked, a process accelerated by ethylene gas. Temperature affects the process of artificial ripening with ethylene. These fruits are transported to distant places in unripe condition to avoid loss and are artificially ripened at the destination market before sale. This is partly because the ripening process … Calcium Carbide is a dangerous and corrosive chemical. Acetylene acts like ethylene and accelerates the ripening process. The industrial grade carbide gas popularly known as ‘masala’ is often used by some unscrupulous traders to release acetylene gas for artificial ripening of fruits Image credit- shutterstock.com. It is generally done for climacteric fruits such as mango, papaya, banana, etc. This usually happens when the harvested fruits are artificially treated without considering the maturity of … Link/Page Citation Byline: Usama Pervez. It may contain traces of heavy metals which can make fruits harmful for human consumption. The most commonly used chemical for artificial ripening is Calcium Carbide (CaC2) and is popularly known as ‘Masala”, though banned under PFA Rules, 1955 and also under Food Safety and Standards (Prohibition and Restrictions on Sales) Regulations, 2011 made thereunder. Fruits are kept in hay-lined wooden boxes called crates. These enzymes convert complex polysaccharides into simple sugars and make the skin of the fruits soft. It's true. The guidance note has been published by FSSAI to create awareness among food business operators/traders, consumers and food safety officials related to different aspects of artificial ripening of fruits. They don’t wait for them to ripen naturally. Artificial ripening is done to achieve faster and more uniform ripening characteristics. Ethylene, acetylene, calcium carbide, propylene, glycol and ethanol are some artificial ripening agents. Calcium Carbide is colourless when pure, but greyish-white to black in colour otherwise, with garlic like odour. 0.50 g is added in 2 ml of ethephon 39% SL for every 1 m3 air tight room / ripening chamber. The natural ethylene in the fruits makes them ripen, so that they are ready to eat by the time you buy them. Due to high cost and scarce availability of ethylene gas, traders often use unsafe and banned substances for ripening fruits like carbide gas which can be potentially harmful to health. In nature fruits ripen after attainment of proper … Almost 80% of the commercially available fruits are ripened using chemicals. Fruit ripening is a natural process which also can be stimulated using different artificial fruit ripening agents. Temperature of fruits should be as close as possible to the temperature mentioned in Table 1, above. The fruits become soft, change in colour, and develop characteristic aroma and flavour, with an increase in sugar level and reduction in acid content. Any source of ethylene gas should not come in direct contact with fruits. The gas used for artificial ripening of green fruit is. Higher exposure may cause a build-up of fluids in the lungs. The rapid ripening of fruits by gases of incomplete combustion—the so-called bivalent compounds—has been known for ages; long ago the Chinese used incense fumes to ripen pears. These enzymes convert complex polysaccharides into simple sugars and make the skin of the fruits soft. Among the pretreatments, which are mostly followed for fruits intended for better consumer acceptance and facilitating better marketing is artificial fruit ripening. Climacteric fruit can both retain the ethylene it produces and absorbs additional ethylene from its environment. In order to reduce the cost of chemical, some ethylene releasing fruits such as papaya and banana can also kept in the same room. The most commonly used chemical is called ethephon (2-chloroethyl phosphonic acid). Instead of introducing ethylene through the gas cylinders, spray of compressed ethylene gas inside the ripening chamber (2.7 litres gas per can for 27 m. Ethylene gas should be sprayed in the empty/open space in the chamber, not directly on the fruits. Among the pretreatments, which are mostly followed for fruits intended for better consumer acceptance and facilitating better marketing is artificial fruit ripening. In artificial ripening, this process is mimicked using chemicals. Unfortunately, farmers have been using artificial ripening agents on fruits and vegetables to induce artificial ripening in them. Ethylene is also a gaseous plant hormone. Artificial ripening of fruits: Unsaturated hydrocarbons like ethylene and acetylene speed up ripening process and cause cosmetic color changes in fruits to impart them a ripened look. Hence farmers in fruit orchards pluck the fruits raw. A group of researchers led by the head of the food science and technology department of Pondicherry University said that they have developed a simple, fast and cost-effective method to detect artificial ripening of fruits by calcium carbide. For uniform ripening, airflow throughout the chamber shall be maintained. According to citizens calcium carbide usage is still rampant for artificial ripening though some vendors in bigger cities are using Chinese ethylene sachets. When Calcium Carbide is used in very raw fruit, the amount of the chemical needed to ripen the fruit has to be increased. Artificial Ripening Of Fruits - 2 Ripening chamber *Fruits should be transferred to ripening chamber once the ripening temperature is attained after pre-cooling by appropriate method. This ripening method may be used where ripening chambers are not available or for in- transit ripening. Fruit ripening process can also be stimulated by applying artificial fruit ripening agents.
