How does the sachet-packaged ethylene ripener work?
Calcium carbide, a commonly used agent in the ripening process, is extremly hazardous because it contains traces of arsenic and phosphorous, high toxic to human. After meeting water, the calcium carbide reacts and produces acetylene gas. Acetylene gas will have effects on the neurological system by regularly-inhaling caused hypoxia. Calcium carbide can cause lots of syndromes, headache, dizziness, mood disturbances, sleepiness, mental confusion, memory loss, cerebral edema and seizures. On the fruits ripened with calcium carbide, the aroma of the fruits is worse than naturally ripening.
Compressed ethylene gas is used extensively to control ripening of fruit such as banana, mango, avocado, citrus and tomato that are picked at commercial maturity, which is a hard green, but mature stage, before ripening starts.
Most of the countries allow to use ethylene gas in ripening and degreen of fruits, even organic.
In USA and Canada, regulations indicate that ethylene is allowed for post harvest ripening of tropical fruit and degreening of citrus.
In Europe, ethylene is allowed for organic bananas and kiwis.
But the gas is highly volatile and explosive. Meanwhile, it is expensive and difficult to handle and unsafe.
Sachet-packaged ethylene ripener can also release ethylene gas with the help of moisture or water.
This would make handling the ethylene much easier and safer and allow for very small amounts to be used to ripen small batches of fruit. It could also potentially be placed in trucks that transport the fruit from the farm so that the fruit arrives at the market perfectly ripe.
