By the time the fruit is ripe, the proportions are reversed.
Bananas also release comparatively large quantities of ethylene gas to help themselves ripen, the gas will even ripen other fruit put in a bag with a ripening banana. Later, the bananas are brought back up to a temperature and humidity that let the enzymes become active again. Too high a temperature destroys enzymes, and too low a temperature can break down the cell walls of the fruit so the contents mix and the fruit oxidizes, browns, and softens abnormally.
The optimum temperature and humidity conditions for ripening are 62 to 68 degrees Fahrenheit and 90 to 95 percent relative humidity. Storage temperatures should be 53 to 56 degrees Fahrenheit.
Bananas contain nutrients that are needed for the human body, it an important fruit for Filipino’s and even all over the world for it contains starch and it can help fight several types of cancer.
A banned ripening chemical agent in many countries, including India, calcium carbide is openly and commonly used for ripening fruit in Pakistan. A very strong reactive chemical, calcium carbide has carcinogenic properties and is used in gas welding for steel goods. Calcium carbide is used for ripening fruit artificially. Since industrial-grade calcium carbide may contain traces of arsenic and phosphorus, the use of this chemical for this purpose is illegal in most countries. Calcium carbide, once dissolved in water, produces acetylene, which
