Feb 27, 2018 · Ethylene gas can be used to de-green citrus and other crops (e.g., pineapples). For these particular fruits, ethylene gas only alters their appearance and does not aid in their ripening process. Ethylene gas works to remove the overlying chlorophyll (green color) to unmask the color underneath.
Jun 29, 2021 · The effects of ethylene gas and fruit ripening may also be affected by other gases, such as carbon dioxide and oxygen, and varies from fruit to fruit. Fruits such as apples and pears emit a greater amount of ethylene gas in fruits, which affects their ripening. The increase in ethylene follows changes in fruit texture (cell wall material is metabolized into smaller molecular weight units producing a softer texture), composition (generally increase in sugars and decrease in acids) and physiology (pigments - bananas go from green to yellow, and volatile flavor compounds increase in concentration.Jan 20, 2021 · Like methane, neither propane nor butane has an odor of its own. However, gas producers add the agent ethyl mercaptan to the gas mixture for safety purposes. This provides a recognizable scent, which will be familiar to anyone who has ever used a gas cylinder BBQ.
Acetylene is not especially toxic, but when generated from calcium carbide, it can contain toxic impurities such as traces of phosphine and arsine, which give it a distinct garlic-like smell. It is also highly flammable, as are most light hydrocarbons, hence its use in welding.
