It is commonly known in the fruit industry that ethylene gas is widely used to boost a fruit's ripeness. i.e. fruits are harvested when they are still unripened, but prior to selling them on the market, they are exposed to a dose of ethylene gas, which are fruit's hormones to convert its internal starch to sugar. Hence, the sweet taste of ripened fruits. I would like to know if the same effect can be applied to flour such as wheat flour, corn flour, etc. Would a flour paste i.e. flour mixed with water, and exposed to ethylene gas convert the starch to sugar? And therefore a sweet sugary solution (mainly glucose) can be extracted after this process. And since flour is in small particles, would stirring the flour paste in presence of ethylene gas to convert it to sugar be an almost instantaneous conversion? As compared to ethylene gas on fruits, which could take 24 hours or more due to its size as a whole fruit as well as exposure to ethylene gas only on the outside skin surface of the fruit? Thx in advance for your answer.
